Patent Abstracts

The yield of solid and liquid hydrocarbons from CO and H₂, or water gas, normally secured by means of a Fe catalyst can be increased by the use of a catalyst prepared by the coprecipitation of Fe and Ca hydroxides from solutions of the chloride or nitrate by means of alkali hydroxides Ca and/or Mg should make up 10-50% of the total weight of the compound calculated as oxides. The mixture is easier to filter than Fe(OII)₃ alone. The catalyst is preferably activated by adding 2-5% of at least 1 metal from the group Ni, Co, and Cu, thus shortening the induction period. The catalyst may be supported on diatomite powder, powdered MgO, pumice, and clay. In 1 example the catalyst is reduced in water gas at 245º.
