Novel zeolite of SAPO-34 was prepared by hydrothermal synthesis. The appropriate composition zone of the reactants for tile formation of pure SAPO-34 was given in Si-P-Al phase diagram. Under specific conditions, the main product was a dense phase material with the atomic ratio of P and Al in the reactants being greater than 1; pure SAPO-34 molecular sieves of different composition can be synthesized in the case of P/A1≤1. Zeolite SAPO-34 cannot be produced from P-Al system, but by adding MgO or ZnO into the system, MAPO-34 and ZAPO-34 can be synthesized. The selectivity with respect to C_2~=—C_4~= and C_2~= in the reaction of methanol conversion to hydrocarbons over HSAPO-34 is 89% and 57—59% respectively, and the C_2~=/C_3~= ratio is 2.24—2.31, all being more advantageous than those of HSAPO-5 and HZSM-5.
