The present invention relates to a method for preparing a catalyst composition for the oligomerization of ethylene and a respective catalyst composition pre-formation unit.

Method for preparing a catalyst composition for oligomerization of ethylene and respective catalyst composition pre-formation unit

A process for preparing a catalyst provided in the form of a metal oxide catalyst having at least one element selected from Mo, Te, Nb, V, Cr, Dy, Ga, Sb, Ni, Co, Pt and Ce. The catalyst is subjected to an aftertreatment to increase the proportion of the M1 phase, by contacting the catalyst with steam at a pressure below 100 bar or by contacting the catalyst with oxygen to obtain an aftertreated catalyst. The aftertreated catalyst may be used for oxidative dehydrogenation processes.

Process for preparing a catalyst, catalyst and process for the oxidative dehydrogenation of hydrocarbons

A plant for producing ethylene having a reactor to effect oxidative coupling of methane, a work-up unit connected to the reactor to separate a first material stream produced by the reactor into a Cmaterial stream and an ethylene product stream and a separation unit connected to the work-up unit to separate the Cmaterial stream into a hydrogen-rich product stream and a hydrogen-lean residual gas stream. The plant also includes a steam cracker to produce () for producing an olefin-containing and hydrogen-containing crude gas stream. The steam cracker is connected to the work-up unit that separates the crude gas stream along with the first material stream into the Cmaterial stream and the ethylene product stream. A portion of the residual gas stream is recycled to the reactor. A process for producing ethylene using the plant is also described.

Plant and method for producing ethylene

The invention relates to processes for production of dimethyl ether from methane or natural gas comprising: a dry-reforming step, wherein methane and carbon dioxide are converted into carbon monoxide and hydrogen, and a DME synthesis step, wherein the carbon monoxide and hydrogen formed in the dry-reforming step are converted into dimethyl ether, wherein the dry-reforming step and the synthesis step are carried out at identical pressures or at pressures, which do not differ more than 3 bar, preferably not more than 1 bar.
