Abstract: Provided are a catalyst for hydrocarbon steam cracking for light olefin production and a method for preparing the same. The catalyst is a simple KMgPO4 catalyst, a supported KMgPO4 catalyst, or a KMgPO4-sintered catalyst. The supported KMgPO4 catalyst is prepared by impregnating a carrier with an aqueous solution of a KMgPO4 precursor and the KMgPO4-sintered catalyst is prepared by mixing a KMgPO4 powder or a KMgPO4 precursor powder with metal oxide followed by sintering.
