PURPOSE:To obtain a liquid hydrocarbon in high yield, suppressing the thermal decomposition of the product, by contacting a stock gas containing lower hydrocarbon with a specific metallosilicate catalyst under a specific condition. CONSTITUTION:The objective liquid hydrocarbon can be produced by contacting (A) a stock gas containing 2-5C paraffinic hydrocarbon and/or olefinic hydrocarbon with (B) a metallosilicate catalyst having a composition represented by the general formula (mol%) Si/Me=15-3,500, OH<->/Sio2=0.3-1.0, H2O /SiO2=30-100, R/R+M=0.05-0.15, NaCl/H2O=0.01-0.06 (R is quaternary alkyl ammonium cation; M is Na or K; Me is B, Al, Ti, etc.) and having an acidity (m-equivalent/g-catalyst) of 0.1-4.5 (total acid), 0.05-2.0 (strong acid) and 0.05-3.0 (weak acid), at a reaction temperature of 220-550 deg.C. |
