Abstract
Mo catalysts supported on MgO, SiO2, Al2O3 and TiO2 were found to produce light alcohols from synthesis gas. Over the SiOO2-supported catalyst, the activity and selectivity for alcohol formation were greatly improved by addition of alkali metal salts. The alcohol formation activity, however, gradually decreased with processing time over Mo-K2CO3/SiO2 catalyst. On the other hand, addition of alkali metal halides to Mo/SiO2 caused increases in the activity and selectivity for alcohols with processing time. Mo-KCl/SiO2 catalyst had the highest activity for alcohol synthesis among all the catalysts studied. The alcohol formation activities of Cr- and W-KCl/SiO2 catalysts have been studied. Over the Cr-based catalyst methanol was the main component of alcohols, while the W-based catalyst gave a high C2+/C1 alcohol ratio.
