NEW METHOD AND CATALYSTS ON INORGANIC CARRIERS FOR CONVERTING C1-C4 HYDROCARBONS TO C2-OLEFINIC HYDROCARBONS

摘要

Catalysts on inorganic carriers for preparing lower hydrocarbon(s) containing C2 having mainly double bond such as ethylene by conversion of lower hydrocarbon(s) containing C1 to C4 such as methane or purified natural gas expressed as following general formula (I): Ma'Pc/S and process for producing thereof, wherein, M is a compound selected from the group of RuCl2(PPh3)3, RuCl2(CO)2(PPh3)2, Ru3(CO)12, RhCl(CO)(PPh3)2, IrCl(CO)(PPh3)2, Pd(PPh3)4, Pt(PPh3)4, RuCl3<.> xH2O, S is an inorganic carrier selected from alpha -Al2O3, gamma -Al2O3, SiO2, SiO2-Al2O3, Y-zeolite, MgO and TiO2, P is a phosphorous compound as promoter selected from PPh3, P(OCH3)3, P(OC2H5)3, P(O)(OC2H5)3, a' is weight percentage of metal in catalyst suitably selected from the range of 0.25 to 5 wt % and c is weight percentage of promoter agent in catalyst, which is 1.0 to 20.0 wt %.
