The mechanical mixtures of Co-Ni/MnO-ZrO2 and zeolite were used as catalysts for the selective synthesis of gasoline by CO hydrogenation. Formation of branched-paraffins was promoted but that of higher hydrocarbons than carbon number of 10 was suppressed by combination with zeolite. The product distribution strongly depended on the type of zeolite catalyst. Pentasil zeolite was active for the formation of branched-paraffins, probably because of the cracking reaction occurring on the strong acid sites. The formation of branched-paraffins was further promoted by ion-exhange with Pt. The mixture of Co-Ni/MnO-ZrO2 and PtH-pentasil zeolite was very active for the formation of gasoline with high octane number.
