Abstract:

In order to explore the conversion of cellulose biomass to ethanol, the author reviewe the current research progress on the pyrolysis conditions of cellulose and converting its pyrolysate (mainly levoglucosan) to ethanol at home and abroad in recent years. It’s found that previous studies are short of caring combinations with different pyrolysis conditions, which may be responsible for the yield of the product such as levoglucosan in the process of the pyrolysis, and also the conventional way via fermenting the hydrolysate of pyrolysate to ethanol is not economical. It would be a trend that the direct conversion of cellulose via pyrolysis to ethanol could be realized by constructing ethanologenic microbial strains with genetic engineering technologies in the future.constructing ethanologenic microbial strains with genetic engineering technologies in the future.
