SAPO-34 분자체 촉매에서 메탄올의 전환반응
Methanol Conversion over SAPO-34 Molecular Sieve Catalyst
초록
합성한 SAPO-34 분자체 촉매에서 메탄올 전환반응을 조사하였다. SAPO-34 분자체 촉매에서 방향족 탄화수소는 생성되지 않고 올레핀의 수율은 높았으나, 탄화수소 침적에 의한 활성저하가 심하였다. SAPO-34 분자체 촉매의 산성도, 메탄올 전환반응에서의 생성물 선택성 및 활성저하 현상을 HZSM-5 제올라이트 촉매와 관련지어 고찰하였다.
Methanol conversiion over synthesized SAPO-34 molecular sieve catalysts was studied. Although the selectivity to olefin was very high and the formation of aromatics hydrocarbon was prohibited over SAPO-34 molecular sieve catalyst, the deactivation due to hydrocabon deposition was serious. The acidity, product distribution in metha-nol conversion and deactivation of SAPO-34 molecular sieve catlyst were discussed comparing with those of HZSM-5 zeolite catalyst.
