A process for the preparation of a lubricating base oil, comprising treating a hydrocarbonaceous product with hydrogen, at elevated temperature and pressure and in the presence of a catalyst, which hydrocarbonaceous product has been prepared by contacting hydrocarbons and/or derivatives thereof with an active hydrogen-containing system by a process which comprises generating a hydrogen-containing plasma and allowing contact of the hydrocarbons and/or derivatives thereof in liquid form with the plasma-generated system and recovering the hydrocarbonaceous product.

Dehydrogenation catalyst, wherein the molar ratio between iron oxide providing agent and potassium oxide providing agent calculated as iron: potassium atomic ratio is in the range of from 1.5 to 60, a K.sub.2 Fe.sub.12 O.sub.19 phase is present in an octahedral Fe.sub.3 O.sub.4 matrix, showing crystalline epitaxy between the hexagonal structure of K.sub.2 Fe.sub.12 O.sub.19 and the (111) planes of the Fe.sub.3 O.sub.4 spinel structure, and showing intense X-ray diffraction peaks in the area of from d=12.4 .ANG. to d=1.60 .ANG.. Process for the preparation of such catalyst and process for dehydrogenation of optionally substituted alkanes into olefins.

A process is disclosed for preparing a hydrogen-rich gas, which is carried out by reacting a carbon monoxide-containing gas with steam in the presence of a catalyst. The catalyst contains a spinel whose composition is expressed by the formula Li.sub.x Cu.sub.(1-x) Fe.sub.5 O.sub.8 in which 0&lt;x&lt;1. Preferably a compound of an alkali metal is added to the catalyst.
