The invention relates to a catalyst for alkene production from synthetic gas and application method thereof, mainly solves problem of poor selectivity of C2-C4 alkene in F-T synthesis. The catalyst provided by the invention comprises the following ingredients by weight: 1-20 parts of silicalite-1 shell and 80-99 parts of kernel, wherein the kernel comprises: a) 80-100 parts of carriers selected from SiO2 or Al2O3, and b) carried on the a), 3-20 parts of at least one metal or oxide of Fe or Co, and c) 1-10 parts of at least one kind of metal of Mn,Zn, Mg or its oxide, and d) 0.1-5 parts of one kind of oxide or hydroxide of K, Na, Rb or Cs, and e) 0.1-2 parts of at least one oxide of Se and Te. The catalyst for alkene production from synthetic gas solves problem of the prior art and can be used in alkene production from synthetic gas.
