O-15 プロセスシミュレーションによるリグニンから1,3-ブタジエン合成プロセスの比較検討

抄録

Three processes for the production of 1,3-butadiene (1,3-BD) from lignin via syngas were proposed and their 1,3-BD yields and input energy such as electric power and heat loads were estimated through process simulation. These processes consisted of lignin gasification, conversion of syngas to light olefins (LOs) via (1) dimethyl ether (DME), (2) methanol, or (3) direct synthesis, and isomerization/dehydrogenation of n-C₄H₈. The process capacity was 200 t/d on a wet lignin basis. When each reaction proceeded ideally, the process featuring the conversion of syngas to LOs via DME exhibited the maximum 1,3-BD yield (13.4 wt%).
