Abstract: 

THE KEY FACTOR THAT HAS IMPORTANT EFFECT ON CATALYST -ACTIVITY OF SYNGAS TO DME (STD) REACTION IS SELECTION OF A SUITABLE SOLID ACID CATALYST FOR METHANOL DEHYDRATION. IN THIS REGARD, ZEOLITES AND Γ-AL2O3 ARE MORE APPLICABLE CATALYSTS WHICH ARE EVALUATED IN THIS REVIEW PAPER. RESULTS FROM LITERATURE, SHOW THAT GENERALLY THE ACTIVITY OF ZEOLITES IS LOWER THAN ALUMINA AND TO MORE IMPROVMENT THE ACTIVITY OF ZEOLITES, THEY ARE MODIFIED BY SOME METHODS SUCH AS SUBSEQUENT DEALUMINATION AND INTRODUCING A METAL COMPOUNDS INTO THE ZEOLITE STRUCTURE. ACCORDING TO LITRETURE THE BEST RESULT OBTAINED FROM ADDITION OF FE, ZR AND MG TO HZSM-5, HY AND FERRIERITE ZEOLITE STRUCTURE. RESULTS SHOWED WHEN ACIDITY OF ZEOLITE IS HIGH, OPTIMAL CONTENT OF ZEOLITE WILL BE DECREASED IN CATALYST. FURTHERMORE, ADDING OF Γ-AL2O3 TO HZSM-5 INCREASED STABILITY OF STD CATALYSTS.
