PURPOSE: To improve the selectivity of an oxygen-containing 2C compound such as ethanol, acetaldehyde, acetic acid, etc., CO and H 2 , by carrying out the reaction in the presence of a Co catalyst modified with Ru and an alkaline earth metal. n CONSTITUTION: An oxygen-containing 2C compound is produced by reacting CO with H 2 in the presence of a Co catalyst modified with Ru and an alkaline earth metal. The compositional ratio of the catalyst is 1/10W10pts.wt. of the alkaline earth metal per 1pt.wt. of Co in terms of metal. The catalyst can be produced by impregnating solutions of a cobalt compound (e.g. cobalt nitrate), a Ru compound (e.g. ruthenium chloride) and alkaline earth metal compound successively or at the same time to a carrier or by the ion-exchange process, dry-mixing process, etc. The catalyst is preferably reduced in H 2 or CO atmosphere before reaction. n EFFECT: The selectivity of the objective compound can be improved remarkably by the addition of the above elements. n COPYRIGHT: (C)1986,JPO&Japio |
