Zusammenfassung:The formation of $C_2-C_{10}$ hydrocarbons from methanol over shape-selective ZSM-5 zeolite catalysts is studied. It seems that $C_2-C_5$ olefins formed from methanol via dimethylether are transformed further to higher hydrocarbons containing higher concentration of aromatics by the acid sites of ZSM-5. Unique cross linked channel structure and its hydrophobicity seems to be mainly responsible for its high activity of ZSM-5 catalyst for the conversion of methanol. 형상 선택성 ZSM-5 제올라이트 촉매상에서 메탄올로부터 $C_2-C_{10}4 의 탄화수소 형성을 조사하였다. 메탄올로 부터 dimethylether를 거쳐 생성되는 $C_2-C_5$의 올레핀들이 ZSM-5의 강한 산점에서 고리화 반응등에 의하여 방향족 화합물이 많이 포함된 탄화수소화합물로 전환된다고 생각된다. 메탄올의 전환반응에 대한 ZSM-5 촉매의 높은 활성과 활성저하에 대한 안정성은 특유의 교차되는 세공관구조와 소수성에 기인하는 것으로 보인다.
