摘要
用盐酸对ZSM-22进行脱铝改性,考察脱铝对催化剂反应的影响,脱铝能使催化剂酸强度有所增强。在连续微反应装置中,氢分压为1MP,质量空速为1.3h-1条件下研究改性后的ZSM-22的反应性能。以正十六烷为探针反应物考察了改性后的ZSM-22的长链烷烃反应性能,结果表明改性后ZSM-22对十六烷有很好的异构化选择性和很好的裂化选择性。
ZSM-22 with hydrochloric de-alumination modified investigate the influence of de-alumination of catalyston reaction.De-alumination catalyst acid strength can be enhanced.Experiments were conductedat the conditions of hydrogen pressure 1.0 MPa, MHSV 1.3h-1,and different reaction temperature for ZSM-22 catalyst of the modified.To n-hexadecane as probe reactant investigated long chain alkanes performance of the modified ZSM-22.The results showed that hexadecane has a very good hydro-isomerization selectivity and hydrocracking selectivity in modification of ZSM-22.
