Co/AC催化剂对F-T合成醇产物的影响

以活性炭为载体,采用真空浸渍法制备Co/AC催化剂,在浆态床反应器中考察反应温度、反应压力和空速等条件对F-T合成醇产物的影响。结果表明,升高反应温度对长链烃和醇的生成有利,醇类的选择性随着反应压力的增大而提高,但反应压力增至3.0 MPa后,继续增加反应压力对醇类选择性变化不大;随着空速的增大,液相产物中醇含量虽然增加,但醇的分布无变化。

Effects of Co/AC catalyst on alcohol products of Fischer-Tropsch synthesis

Activated carbon supported cobalt based catalyst for Fischer Tropsch synthesis was prepared by vacuum impregnation method.The influence of reaction temperatures,reaction pressure and raw gas space velocity on alcohol product of F T synthesis was invetigated in a slurry reactor.The results showed that the increase of reaction temperature was beneficial to the production of long chain hydrocarbon and alcohols;the selectivity to alcohols enhanced with the increase of reaction pressure,but the selectivity to alcohols changed little when the reaction pressure was increased to 3.0 MPa;although the content of alcohols in the liquid products enhanced with the increase of GHSV,the distribution of alcohols was not changed.
