摘要： A two-stage process for the manufacture of methane from hydrocarbons is described. In the first stage, the hydrocarbons are converted into methane-rich gases, using the nickel catalyst described below. The cracked gases thus obtained are cooled and converted into methane-rich gases in a further catalytic process stage, using a methanization catalyst or the nickel catalyst mentioned below. To produce the nickel catalyst, the compound Ni.sub.6 Al.sub.2 (OH).sub.16.CO.sub.3.4H.sub.2 O is prepared in aqueous solution. The catalyst is obtained from this compound by drying, calcination and subsequent reduction in a stream of hydrogen whilst maintaining very specific temperature gradients between the drying stage and the calcination stage.

摘要： The compound Ni.sub.6 Al.sub.2 (OH).sub.16. CO.sub.3. 4H.sub.2 O is isolated from aqueous solution. The catalyst is obtained from this compound by drying, calcination and subsequent reduction in a stream of hydrogen, whilst maintaining very specific temperature gradients between the drying stage and the calcination stage. A process for the manufacture of gases containing methane from hydrocarbons by steam cracking, in which the abovementioned catalyst is employed, is also described.

C., and are used for the catalytic preparation of propanediols of the formula ##STR1## where the R's may be identical or different and each is an aliphatic, araliphatic or aromatic radical, or the two R's together with the adjacent carbon atom are members of an alicyclic ring, by hydrogenating hydroxypropionaldehydes of the formula ##STR2## where R has the above meanings, and to processes for the preparation of propanediols, using such catalysts.
