Dear Mr. Bland: Thank you for your very useful, concise and instructive primer on hydrocarbon gases. In particular you laid to rest the old saw about making biogas or gasifier gas into methanol - the compressor costs become horribly expensive at small scales and make such process only suitable for large-scale systems. Of course you still have to clean up the gas to remove tars, etc.... I hope this will lay to rest this whole business. One question though: what about making H2? I would be interested in your answer. Sincerely, John R.
