Re: [biofuel] Syngas to methanol
Walt Does you have any reference files I could look at please? I know that Sasol in South Africa have been using a GTL technology via an Iron-Oxide catalyst to produce very low sulphur diesel / petrol since the 1950's. The catalyst is now changing over to cobolt to reduce / prevent the formation of waxes. Mark Yahoo! Messenger - Communicate instantly...Ping your friends today!

The research was done using a Department of Energy grant, so my understanding is that there's a public interest in the patent. When I spoke with the inventor, he didn't have a problem with us working on utilizing his work. Anyone familiar with the niceties involved in public use of research funded by the DoE?

The coordinating ligands can be selected from the group consisting of N-donor ligands, P-donor ligands, O-donor ligands, C-donor ligands, halogens and mixtures thereof. Etc.

Just as importantly, it allowed the use of a micro reactor, i.e. the engineering tests that were used to design the plant described in the link below was a six foot length of one inch diameter stainless steel pipe. http://www.lanl.gov/projects/cctc/factsheets/estmn/csliquiddemo.html The second involves a co-catalyst system developed by Dr. Mahajan which allows the reaction to proceed at much reduced temperatures and pressures (100 PSI and 150 C) The co-catalyst is also much less sensitive to the presence of CO2 in the feed stream. This route is especially interesting because it raises the single pass conversion rate up to better than 90%. At that point, you can burn off the uncondensed gas and not have to worry about the accumulation of inert gases (i.e. N2) in the reactor.
