Catalytic conversion of methanol to olefins over rare earth (La, Y) modified SAPO-34
SAPO-34 modified with lanthanum and yttrium exhibited higher selectivity to light olefins, lower methane formation, and longer lifetime (prolonged by 20%) than the parent SAPO-34 in the process of methanol conversion to olefins. The modified catalytic performance could be ascribed to the incorporation of La3+ and Y3+ into the framework of SAPO-34.
