Liquid hydrocarbon is prepared with high efficiency from hydrocarbon gas containing C2-C5 paraffinic hydrocarbons and/or C2-C5 olefinic hydrocarbons by bringing the gas into contact with a metallo-silicate catalyst having the following chemical composition in mol %: Si/Me:15-3500 OH-/SiO2:0.3-1.0 H2O/SiO2:30-100 R/(R+alkali metal):0.05-0.15 NaCl/H2O:0.01-0.06 where R is quaternary alkylammonium cation, alkali metal is Na or K, Me is metal ion of B, Al, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, Ga, Ge, Zr, Mo, W, La or Sc, and having the following acidity per g of catalyst: total acid 0.1-4.5 milli-equivalent strong acid 0.05-2.0 milli-equivalent weak acid 0.05-3.0 milli-equivalent. |
