摘要：
The hydrogenation of carbon dioxide was examined over various composite catalysts composed of Fe-Zn-M catalyst and zeolite. Fe-Zn-Zr/HY composite catalyst was confirmed to be efficient for the highly selective production of isobutane, which is regarded as a synthetic intermediate of MTBE (methyl tert-butyl ether). The composite catalyst of Fe-Zn-Zr catalyst with H-ZMS-5 formed C5+ hydrocarbons in good yield. The ratios of branched hydrocarbons in C5+ ones, which are suitable for high-octane gasoline, were over 90%.
