     ZnS as such, or with the addition of 5% of CdS, MoS₂, and CuS, decomposes MeOH 100% at 300°-375°.  ZnS, with the addition of 1% of the above admixtures and Sb₂S₅ decomposes MeOH 100% at 300°-325°.  ZnO decomposes MeOH completely at a temperature exceeding 400°.  The composition of the gas obtained is near the stoichiometric ratio CO:H₂=0.5 only for ZnS, further additions considerably increase the H₂ ratio, particularly the 1% admixtures (1.5-2.5 times).  An addition of 1% of activators increases the activity of the catalyst noticeably, but it lowers the amount of CO in the gas.  The catalysts may be suitable for MeOH synthesis carried out under pressure.
