The present invention relates to a porous solid acid catalyst for the production of light olefins, based on the oxide type, HZSM-5 42.0-60.0 wt% Si / Al molar ratio 15-300, layered compounds 12.0-38.0 wt%, Al 2 O 3 Obtained by solid chemical reaction by crosslinking and heat treatment of a raw material mixture comprising 1.0 to 20.0 wt%, P 2 O 5 1.0 to 4.0 wt%, SiO 2 10.0 to 15.0 wt%, and B 2 O 3 0.5 to 2.5 wt% And a porous material having a crystal structure different from that of the raw material. The catalyst is excellent in catalytic cracking activity required to produce light olefins from a full range naphtha containing C 2-12 hydrocarbons.n n n n Light olefin, catalytic cracking, full range naphtha, crosslinking, solid chemical reaction, ethylene, propylene |
