• Hybrid catalysts composed of the physical mixture of methanol synthesis catalysts and Y-type zeolites gave C<SUB>3</SUB> and C<SUB>4</SUB> paraffins from synthesis gas at 2.1 MPa, with a selectivity higher than 70%. The product contained small methane and little aromatic hydrocarbons. The hydrid catalyst kept its activity and selectivity at almost constant level for 50 h. The yield of hydrocarbon was much higher than the level estimated from the thermodynamic equilibrium of methanol formation from synthesis gas. The yield of hydrocarbon increased monotonically with the increase in temperature while the carbon number distribution of the product shifted to lower side between 523 and 623 K. The production of hydrocarbon was accompanied by the nearly equal amount of CO<SUB>2</SUB>.
