制备了碳化钨与SAPO-11分子筛的混合催化剂和复合催化剂,并制备了Pt/SAPO-11参比催化剂,比较了它们对正十六烷的临氢异构化的催化性能。结果表明:WC(20%)/SAPO-11混合催化剂对正十六烷的转化率略高于Pt(0.5%)/SAPO-11,而WC(10%)-SAPO-11和WC(20%)-SAPO-11复合催化剂的转化率都低于Pt(0.5%)/SAPO-11;WC(10%)-SAPO-11和WC(20%)SAPO-11复合催化剂的异构烷烃产率和选择性都高于WC(20%)/SAPO-11混合催化剂,但仍然比Pt催化剂低很多。 The mixed catalyst and composite catalyst of tungsten carbide and SAPO-11 molecular sieve were prepared, and Pt / SAPO-11 reference catalysts were prepared, and their catalytic performance for hydroisomerization of n-hexadecane was compared. The results showed that the conversion of n-hexadecane to WC (20%) / SAPO-11 was slightly higher than that of Pt (0.5%) / SAPO-11, ) -APO-11 composite catalyst was lower than that of Pt (0.5%) / SAPO-11; the isoparaffin yield of WC (10%) - SAPO-11 and WC The selectivity is higher than the WC (20%) / SAPO-11 mixed catalyst, but still much lower than the Pt catalyst.
