Abstract：
 The invention relates to a method for preparing composite modified catalyst, used to prepare biological ethane. Wherein, it comprises that preparing composite modified catalyst, and using said catalyst to prepare biological ethane; said catalyst uses HZSM-5 molecule screen as powder, uses emerge method to lead in Zn<2+ and Mn<2+ metal ion, to be baked, compressed, rolled, and screened, to obtain the composite modified Zn/Mn/ZSM-5 catalyst with high catalysis activity. And its application uses biological ethane as material, adds said catalyst, under normal pressure, controls airflow speed, reaction temperature and reaction time; dewaters to obtain biological ethane, while its transformation rate and selectivity are both higher then 95%. The invention has low cost and simple control.
