Hydrocarbon conversion catalysts, esp. for reforming - contg. platinum gp. metal, silicon and gp=ivA metal

摘要

Catalysts comprise 100 pts.wt. of a support, 0.05-0.6 (pref. 0.1-0.5)pts.wt. of a Pt-gp. metal, 0.02-0.2 (pref. 0.04-0.08)pts.wt. of Si, 0.005-5 (pref. 0.05-3, esp. 0.4-1.5)pts.wt. of Ti, Zr or Hf, and 0.1-15 pts.wt. of a chalogen. The catalysts can be used for reforming,aromising, hydrocracking, dealkylation or isomerisation of hydrocarbon feeds. They are esp. useful for reforming or aromising in a reaction system comprising several mobile-bed reactors in series, having high stability and selectivity (e.g. giving C5+ yields of 70-80%). The support is pref. alumina and the Pt-gp. metal is pref. Pt or Ir.
