Ulev,
Can you give Prof. Bayer's full name or patent number so I can research this work? Thanks.
Prof. Dr. Ernst Bayer
German Pat. DE 304 2964, September 14 1982, European Pat. 0052334, November 10 1981 und US Pat. 5,114,541, May 19 1992
All patents expired a while ago
Hope this helps
I wonder if anyone has heard more about Alphakat or otherwise been able to validate that their technology really works? As of May 2007, my local county government in Hunterdon County NJ is on their way to building a $10M pilot plant using Alphakat's technology, and from the preliminary research I have done it looks like there may be reason to worry. However, I want to be fair minded and I am looking for independent third party assessments that validate the technology. Independent Auditors reports from existing plants that validate effectivenes of operation, prove the costs of operation, confirm production numbers are good too. Or university studies or peer-reviewed articles in leading journals would help. Has anyone come across this kind of information?
If you have information or insights please help. This is of vital importance to a lot of people, but I cannot confidently discuss this with local, regional and state regulatory authorities until I am sure that my facts are in order.
Thanks in advance for your thoughts or information,
Bill in Hunterdon County New Jersey
Bill, can you answer a few questions about this pilot:
What is the intended feedstock?
What is the proposed capacity?
Who is selling?
Has anyone talked to these guys in Canada yet? http://www.barriemetals.com/index.php Their plant doesn't seem to run as intended, to say the least.
Hey ulev.
I think your correct in ur comments that KDV is all talk and no walk. Not a single plant can show 6 months of optimized function. Without 6 months of scaled optimized performance, early adoptors arnt early adoptors, they are canaries in the coal mine.

froggy: Hey ulev. I think your correct in ur comments that KDV is all talk and no walk.

I would rather be quoted with "a lot of talk and too little walk".
I would also say, that if for any reason we don't know yet, somebody wants to invest in new technology, this is certainly not pure stupidity. A buyer should understand, however, that he is taking a high risk and that all possible measures for risk control should be implemented in managing such a project.
The first step is for sure a full blown due dillicence of the technology and the credibility of the people behind it. After that, the project plan should involve a step by step approach, where payments for the next phase depend on successful delivery of the step before. If, in this case somebody is willing to just sign a 10 Million deal for an Alphakat plant without any safety net in place, I would simply call such an approach suicidal.
Hi there!
I have a question concerning the chemical background of the reactions taking place in the KDV reactor.
I read in the patent by Koch that he is using some kind of heavy oil residue (e.g. bunker oil) to disperse the dry, solid feedstock before it enters the reactor.
Does anybody know how this heavy oil residue contributes chemically to the reaction?
Ulev, I see that you have a very good background in this field. Perhaps you can give me a hint on this.. Thanks
Hallo all,
a friend of mine has seen the Madrid plant operate on paper waste and other stuff.
They do begin with w.e.o. or the like.I will hopefully see it in a couple of weeks time.
Koch is no longer on board, they say. There were problems.
i´ll keep you informed
Rolf
Trex,
the heavy oil is not meant to react in any way. It's supposed to act purely as a carrier liquid.
Of course, this leaves room for a lot of doubts, as per definition the process would have to crack the long hydro carbon chains of the carrier oil as well. Unfortunatly there is no objective information available, how much of this oil disappears during the process. I know for a fact, that Green Power has used diesel and used engine oil as a carrier during demonstrations. No wonder, what came out was diesel...
When we run the process in our small lab reactor (works completely different than the Alphakat thing) we mostly use some liquid oil (like canola oil) to create an emulsion, as we have learned, that the process starts a lot quicker that way. This has to do with the much better energy distribution in the emulsion compared to dry feedstock. This effect only impacts the start of the reaction process.
Rolf - Ulev,
thanks for the reply.
Ulev, what range of temperatures are you using for your process? If it's over ~250°C then the canola oil would be depolymerized too.
Another question: how is KDV translated in english? Catalytic Low Pressure Liquefaction perhaps. But is it then a liquefaction process, in the context that liquefaction processes require high pressure and aqueous medium during operation?

Trex: Ulev, what range of temperatures are you using for your process? If it's over ~250°C then the canola oil would be depolymerized too.
Reaction starts somewhere above 270 degrees. Optimal is up to 400 degrees, strongly dependant on feedstock. Canola oil will be converted too.
Trex: Another question: how is KDV translated in english? Catalytic Low Pressure Liquefaction perhaps. But is it then a liquefaction process, in the context that liquefaction processes require high pressure and aqueous medium during operation?
You have the (direct) translation right, but it has nothing to do with your quoted liquefaction process. Standard English term is Catalytic Depolymerization or CDP.

diesel or bio-fuel? is there anyone who use these oil in his car
normally this oil has to be a mixt of gosoline/diesel and kerozene, it s impossible to have just diesel.
the process is well known when your input materials is is not heterogen, youcan optimize your temperature and catalyst..when you mixe the inputs you will loose your yield and deactivate rapidly your catalyst.years talking without results, i would like to see more results run to run and day to day during a long period, before believing in this process.
quick: diesel or bio-fuel? is there anyone who use these oil in his car.

It is pure diesel (=gasoil). Whether it is bio-fuel or not depends on the feedstock. You can use it in any diesel engine.
quick: normally this oil has to be a mixt of gosoline/diesel and kerozene, it s impossible to have just diesel.
This is nonsense. You obviously don't even understand the basics of CDP nor the basic crude oil distillation process at the refinery.
quick: the process is well known when your input materials is is not heterogen, youcan optimize your temperature and catalyst..when you mixe the inputs you will loose your yield and deactivate rapidly your catalyst.
Nonsense again. Result from feedstock mix can be anything from real bad to ideal. The rate of catalyst deactivation depends on a lot of process parameters. Feedstock quality is only one of them.
quick: years talking without results, i would like to see more results run to run and day to day during a long period, before believing in this process.
How come you know all that? You obviously haven't been at our R&D facility.
LOL... I just started writing to quick and my buddy ulev jumps in...
It took 47 years for the TV to become commercial and it took another 20 years after than for the goldenage of TV. Have patience grasshopper...
You just misunderstood me (Jumper). I was reading the departed professor Bayer patent claims. Dr. Bayer never claimed to be able to produce diesel oil from biomass. As I told I was visiting the Spanish KDV plant. It was built inside a small (I guess approximately 150 square meters) warehouse in a Madrid light industry zone. I believe that the whole thing was illegal. I can´t understand that it can be allowed to have such a machine without specific safety measures. The machine could not be intended to work more than one hour at a time anyway. We are very interested in the subject and also to develop a project with reliable partners. However, if someone asks me a lot of money for a machine, a heavy amount of money for a license to use the machine that he sold me, than the only thing that someone not completely out of his mind will ask back is a bank guarantee or a state export guarantee. The problem is that Mr. Koch is not selling the machine as an experimental prototype that could be further developed. He is selling the machine as a full functional system.
Yes, we are interested in developing a project with reliable partners. Please send me an e-mail.

hello mister ulev you suppose to have an R&D, so what is exactley you result wit differents organic feedstock
is it really diesel ...
I m not going to discuss with you any basics because you seem like somebody who just jump on something without any science
we can obtain some diesel-like with oil/fat/some plastics........others feedstock just forget them!!!
good luck......what's means depolymerisation, when you don t have any polymers?

You ask questions, you insult me, you tell nonsense...
If I may ask, what is the exact purpose of your post adressing me personally?
Does anyone here has an idea about the patent which the Global Finest Technologies (http://www.globalfinest.com/tech ) are talking about?
They claim that their technology is patented, but there is not any other information about that on their web page.
