Abstract

Abstract

The modified HZSM-5 zeolite which contains MgO was prepared by impregnating Mg(NO₃)₂·6H^₂O ethanol solution with HZSM-5 and then mixed mechanically with methanol catalyst (MeLi) for LPG synthesis. The effects of MgO were investigated in a fixed bed reactor for LPG synthesis. The result showed that with increase of the MgO addition, the strong acid of HZSM-5 zeolite was decreased. The best mass content of MgO in the HZSM-5 was between 0.25%～1.00%. The hybrid catalyst, which consisted of modified HZSM-5 and MeLi, demonstrated a high activity, high selectivity to the target product C₃ and C₄ hydrocarbons and long catalyst lifetime.
