Abstract:
The present disclosure relates generally to processes for performing an integrated Fischer-Tropsch synthesis of hydrocarbons using methanol. In particular, the disclosure relates to a process comprising: providing a first feed stream comprising H 2 and CO 2 ; contacting the first feed stream with a hydrogenation catalyst for form a first product stream comprising methanol; providing a second feed stream comprising at least a portion of the methanol of the first product stream; contacting the second feed stream with a methanol decomposition catalyst to form a second product stream comprising CO and H 2 ; providing a third feed stream comprising H 2 and at least a portion of the CO of the second product stream; contacting the third feed stream with a Fischer-Tropsch catalyst to provide a third product stream comprising C 5+ hydrocarbons.
Abstract:

Abstract:
A process is described for producing a hydrocarbon product. In examples, the process comprises contacting a feedstock with a catalyst composition in the presence of hydrogen, the feedstock including a lipid, and the catalyst composition being active for conversion of the lipid to the hydrocarbon product in a single step. The catalyst composition comprises an M1-[Sup] catalyst, where M1 is an active metal and [Sup] comprises an acidic support. In examples described, the process is used in the production of diesel-range fuel and/or jet fuel from lipid having a high yield of C 11 -C 24 branched alkanes with high cetane value and low freezing point. In examples, the hydrocarbon product includes greater than 70 % measured by weight of C 11 -C 24 alkanes based on the weight of the lipid, and the content of branched alkanes of the C 11 -C 24 alkanes is greater than 60 % measured by weight of branched C 11 -C 24 alkanes based on the weight of the C 11 -C 24 alkanes.
Abstract:
A process for producing glycolic acid from carbon monoxide and formaldehyde, optionally in a solvent, using a catalyst comprising an acidic polyoxometalate compound insoluble in formaldehyde, glycolic acid and the optional solvent, wherein the insoluble acidic polyoxometalate compound has a concentration of acid sites of greater than 60 μmol g -1 on the external surface and/or has a Hammett Acidity value of less than -12.8.
Abstract:
The present invention relates to a process for the production of ethanol, and optionally methanol, from synthesis gas. In particular the present invention relates to a process for the production of ethanol from a carbonaceous feedstock; wherein the carbonaceous feedstock is first converted to synthesis gas which is then converted to methanol, which is then converted to ethanoic acid, which is then esterified and which is then hydrogenated to produce ethanol in the same alcohol synthesis unit in which the said synthesis gas is converted to methanol.
Abstract:
The present invention relates to a process for the production of ethanol (and optionally methanol) from a carbonaceous feedstock; wherein the ethanoic acid (produced by a multi-step process from the carbonaceous feedstock) is hydrogenated to produce ethanol in the same reactor unit and with the same catalyst(s) that is used to produce methanol from synthesis gas.
Abstract:
The present invention relates to a process for the conversion of n-butanol to di-isobutene, in particular the present invention relates to the conversion of synthesis gas to di-isobutene.
