Middle distillate hydrocarbons are produced from feed mixtures of carbon monoxide and hydrogen by contacting said feed at elevated temperature and pressure in a first stage with certain impregnated catalysts and contacting at least the middle distillate fraction of the product of the first stage in the presence of hyrogen with a catalyst containing at least one metal having hydrogenation activity supported on a porous carrier.

Process for the preparation of middle distillates

An improved process for the preparation of certain crystalline iron silicates particularly suitable for converting acyclic oxygen-containing hydrocarbons into aromatic hydrocarbons wherein use of high silicon content compounds together with certain amines results in silicates having unexpected catalytic stability.

Process for the preparation of crystalline silicates

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 for upgrading of Fischer-Tropsch hydrocarbon synthesis product which comprises separating said product with at least one of a light boiling fraction and/or heavy boiling fractions and contacting said fraction(s) with certain crystalline silicates to obtain an aromatic gasoline and/or a fuel oil having a lowered pour point.
