    摘要: The invention relates to a method for converting ethylene into propylene consisting in reacting said ethylene with a supported metal compound comprising an aluminium oxide based support to which a tungsten hydride is grafted. Said reaction is carried out at a temperature ranging from 20 to 600° C., preferably between 50 and 350° C., at an absolute pressure ranging from 0.01 to 8 MPa, preferably between 0.01 and 1 MPa. A catalyst is regeneratable by introducing hydrogen at a temperature of 50-300° C.

    摘要: The invention relates to a process for producing ethane comprising contacting methane with a metal catalyst selected from metal hydrides, metal organic compounds and mixtures thereof. It also relates to a process for the conversion of methane to carbon-containing products comprising contacting methane with a metal catalyst comprising at least one metal, Me, chosen from the lanthanides, the actinides and the metals from Groups 2 to 12 of the Periodic Table of the Elements, so as to produce ethane in a proportion of at least 65%, especially at least 98% or 99% by weight with respect to carbon-containing products formed in the process. The process can be a single-step process, preferably carried out under conditions involving a non-oxidative catalytic coupling of methane, in particular under operating conditions maintained substantially constant, preferably continuously, during the ethane production, e.g. at a temperature ranging from −30° C. to +80° C., preferably from 20° C. to 500° C., under a total absolute pressure ranging from 10−3 to 100 MPa, preferably from 0.1 to 50 MPa. The metal catalyst may be chosen from metal catalysts supported on and preferably grafted to a solid support. One of the main advantages of the present invention is to produce ethane with a very high selectivity.
