The present invention relates to an improved process in term of selectivity and catalyst activity and operating life for the conversion of hydrocarbons to ethanol and optionally acetic acid in the presence of a particulate catalyst, said conversion proceeding via a syngas generation intermediate step

Process for the conversion of hydrocarbons to c2-oxygenates

The present invention relates to an improved process for the conversion of carbon oxide(s) and hydrogen containing feedstocks to oxygen containing hydrocarbon compounds in the presence of a particulate catalyst. In particular, the present invention relates to an improved process for the conversion of carbon oxide(s) (CO and CO2) and hydrogen containing feedstocks, e.g. synthesis gas or syngas, to alcohols in the presence of a particulate modified molybdenum sulphide based catalyst, or a modified methanol based catalyst and/or a modified Fischer-Tropsch catalyst.

Process for the conversion of synthesis gas to oxygenates

A process for forming an alcohol fraction boiling in the range of motor gasoline that is enriched in higher alcohols, comprises contacting a mixture of hydrogen, carbon monoxide and a lower alkanol with a catalyst comprising: (1) a first component comprising molybdenum, tungsten or a mixture thereof in free or combined form; (2) a second component comprising an alkali or alkaline earth element or a mixture thereof in free or combined form; (3) an optional third component comprising cobalt, nickel or iron or a mixture thereof in free or combined form; and (4) an optional fourth component comprising a support, under conditions sufficient to convert at least some of the one or more lower alcohols to higher alcohols.

Preparation of ethanol and higher alcohols from lower carbon number alcohols

Systems and methods conducive to the formation of one or more alkene hydrocarbons using a methane source and an oxidant in an oxidative coupling of methane (OCM) reaction are provided. One or more vessels each containing one or more catalyst beds containing one or more catalysts each having similar or differing chemical composition or physical form may be used. The one or more catalyst beds may be operated under a variety of conditions. At least a portion of the catalyst beds may be operated under substantially adiabatic conditions. At least a portion of the catalyst beds may be operated under substantially isothermal conditions.

Oxidative coupling of methane systems and methods

The present invention provides various processes for producing light olefins from methanol and ethanol, optionally in a mixed alcohol stream. In one embodiment, the invention includes directing a first syngas stream to a methanol synthesis zone to form methanol and directing a second syngas stream and methanol to a homologation zone to form ethanol. The methanol and ethanol are directed to an oxygenate to olefin reaction system for conversion thereof to ethylene and propylene.

Methanol and ethanol production for an oxygenate to olefin reaction system

A method for converting methane to higher molecular weight hydrocarbons wherein hot oxidative coupling reactor effluent is briefly contacted with a C2 to C20 alkane quench material to remove part of the heat contained in the raw reactor effluent, and is then further quenched by thermal quenching means to achieve a temperature which discourages retrograde reactions.

Oxidative coupling process for converting methane and/or natural gas to more transportable products

Conversion of syn gas to methanol and higher alkanols wherein alkanols are added to a syn gas reactor. Lower alkanols are homologated to higher alkanols. Liquid methanol is added as an interstage quench.
