美国化学工程师协会于1980年8月在波特兰市召开第89届全国会议。会上谈到,用木材废料制成的乙烯在本世纪末将能与石油乙烯相竞争。“化工设备公司”的工程设计总经理巍斯·劳伦斯介绍了一种将木材纤维素酸水解、所得糖类发酵成酒精、再用催化脱水使酒精变成乙烯的工艺过程,并估算了这种工艺的经济效果。 The American Society of Chemical Engineers held the 89th National Conference in Portland, August 1980. At the meeting, it was mentioned that ethylene made from wood waste will compete with petroleum ethylene by the end of this century. “Ms. Lawrence, general manager of engineering design,” introduced a process for the hydrolysis of wood cellulose, the fermentation of the resulting sugars into alcohol, and the use of catalytic dehydration to convert alcohol into ethylene. The economic effect of this process.
