A hydrocarbon mixture is prepared by contacting a mixture of H2 and CO with a mixture of two catalysts, of which one is capable of catalysing the conversion of the H2/CO mixture into oxygen-containing compounds and the other one of which is a crystalline aluminium silicate with a SiO2/Al2O3 molar ratio between 100 and 250, which silicate after calcination during 1 hour in air at 500 DEG C shows an X-ray diffraction pattern with the four strongest lines at d( ANGSTROM ) 11.1 +/- 0.2; 10.0 +/- 0.2; 3.84 +/- 0.07 and 3.72 +/- 0.06. The silicate is prepared from an aqueous mixture containing one or more alkali metal (M) compounds, one or more Al compounds, one or more Si compounds which after drying and calcination yield a product of more than 90 %w SiO2 and one or more quaternary alkylammonium halides (R4NX), the various compounds being present in the following molar ratios, expressed, except the quaternary alkylammonium halides, in moles of their oxides: <IMAGE> |
