The invention relates to a method for the preparation of a catalyst for water gas and hydroformylation reactions, which catalyst includes as active components a ruthenic carbonyl and a heterocyclic base on a solid carrier. The catalyst is formed by one or more successive reactions in which the ruthenic carbonyl is fixed from a gas phase onto the carrier and the heterocyclic base is fixed onto the carrier either from a gas phase in the same was as in the case of the ruthenic carbonyl, or from a solution or melt of the heterocyclic base.

The present invention concerns a catalyst system and a process for selectively producing alcohols from olefines and synthesis gas. The catalyst system comprises one or several metal cluster compounds belonging to the cobalt group on an inorganic carrier and an amine of the form NR.sub.1 R.sub.2 R.sub.3, where R.sub.1,R.sub.2 and R.sub.3 are either hydrogen or an aliphatic or aromatic group containing 1 to 8 carbon atoms.

Procedure for producing alcohols and aldehydes from alkenes and

A two step process for producing isobutylene from propylene and synthesis gas. In the first step, propylene is contacted with synthesis gas at elevated temperature in the presence of a catalyst system containing a mixture of monometal compounds M.sub.4 (CO).sub.12 and M'.sub.4 (CO).sub.12 and/or bimetal compound M.sub.2 M'.sub.2 (CO).sub.12 where M and M' are different metals of the cobalt group. The alcohol mixture thus-obtained is dehydrated in the second step, to produce a product fraction containing a large amount of isobutylene.

A catalyst for directly converting olefins to alcohols by hydroformylation in a single step, the catalys comprising a mixture of two monometal cluster compounds M.sub.4 (CO).sub.12 and M'.sub.4 (CO).sub.12 where M and M' are compounds of the cobalt group.
