Abstract:
Catalytic conversion of bio-oil into light olefins was performed by a series of molecular sieve catalysts, including HZSM-5, MCM-41, SAPO-34 and Y-zeolite. Based on the light olefins yield and its carbon selectivity, the production of light olefins decreased in the following order:HZSM-5>SAPO-34>MCM-41>Y-zeolite. The highest olefins yield from bio-oil using HZSM-5 catalyst reached 0.22 kg/kgbio-oil with carbon selectivity of 50.7% and a nearly complete bio-oil conversion. The reaction conditions and catalyst characterization were investigated in detail to reveal the relationship between the catalyst structure and the production of olefins. The comparison between the pyrolysis and catalytic pyrolysis of bio-oil was also performed.

摘要:
研究了用一系列不同类型的分子筛催化剂催化转化制取低碳烯烃的过程,测试的催化剂包括HZSM-5、MCM-41、SAPO- 34和Y型分子筛.按照低碳烯烃的绝对收率和选择性,催化剂的活性排序为:HZSM-5>SAPO-34>MCM-41>Y型分子筛.研究表明,使用HZSM-5分子筛催化剂,获得的生物油最大低碳烯烃收率约为0.22 kg/(kg生物油),低碳烯烃的选择性约为50%,且生物油几乎实现完全转化.同时还研究了反应条件对生物油制低碳烯烃的影响.为了弄清催化剂结构与和低碳烯烃形成之间的关系,对相关催化剂进行了详细表征,对生物油热裂解和催化裂解过程进行了详细比较.
