A process is disclosed for the preparation of an aromatic hydrocarbon mixture from a mixture of carbon monoxide and hydrogen using a mixture of two catalysts; one is a conventional catalyst for the conversion of a CO/H.sub.2 mixture into acyclic oxygen-containing hydrocarbons and the other is a certain crystalline silicate containing at least one element selected from manganese, clacium, magnesium and titanium, and the alumina to silica ratio is greater than 0.005.

Process for the preparation of hydrocarbons from synthesis gas

A process is disclosed for the preparation of a hydrocarbon mixture by contacting in a first stage a feed mixture of hydrogen and carbon monoxide with an H.sub.2 /CO molar ratio of less than 1.0 with a trifunctional catalyst combination containing (a) at least one metal component having catalytic activity for conversions of a H.sub.2 /CO mixture into acyclic hydrocarbons, and/or acyclic oxygen-containing hydrocarbons, (b) at least one metal component for the conversion of an H.sub.2 O/CO mixture into an H.sub.2 /CO mixture, and (c) a certain crystalline silicate containing at least one trivalent metal selected from aluminum, iron, gallium, rhodium, chromium and scandium, wherein the molar ratio of the trivalent metal oxide to silica is less than 0.1; adjusting the H.sub.2 /CO molar to at least 1.5 by adding H.sub.2 O, if necessary; followed by contacting in a second stage at least the C.sub.2 - fraction of the reaction product from the first stage with a bifunctional catalyst combination containing at least one metal component with catalytic activity for converting an H.sub.2 /CO mixture into acyclic hydrocarbons and also at least one metal component with catalytic activity for converting an H.sub.2 O/CO mixture into an H.sub.2 /CO.sub.2 mixture.

Process for preparation of hydrocarbons

A process is disclosed for the preparation of aromatic hydrocarbon mixtures from a feed mixture of carbon monoxide and hydrogen by contacting said feed at elevated temperature and pressure with a mixture of two catalysts; one capable of converting said feed into acyclic oxygen containing hydrocarbons and the other certain crystalline gallium silicates.

Process for the preparation of hydrocarbons

A process is disclosed for the preparation of an aromatic hydrocarbon mixture from a mixture of carbon monoxide and hydrogen using a mixture of two catalysts; one for the conversions of a CO/H.sub.2 mixture into acyclic oxygen-containing hydrocarbons, and the other is a certain crystalline silicate having very high silica to alumina ratio, capable of catalyzing the conversion of acyclic oxygen-containing hydrocarbons into aromatic hydrocarbons.

A process is disclosed for the conversion of certain difficultly converted aliphatic oxygen-containing hydrocarbons to aromatic hydrocarbons by contacting them in low concentrations with certain other aliphatic oxygen-containing hydrocarbons over certain crystalline silicates containing iron in their structure.

Process for the preparation of an aromatic hydrocarbon mixture using

Synthesis gas is converted into gasoline by contacting the gas with a crystalline aluminosilicate zeolite catalyst, the process being characterized by conversion of by-product isobutane into gasoline by alkylation.
