摘要：The product distributions of Fischer-Tropsch synthesis over Co/AC catalyst are investigated under different reaction conditions in an integral fixed bed reactor. It is found that the product distributions deviate from the ASF distribution. The deviation from ASF distribution is analyzed by taking the readsorption of alkenes and the following secondary reaction into consideration. It is noted that the contents of alcohol, alkene and alkane decline with the increasing carbon number, showing a slighter declining tendency of alkanes than those of alkenes and alcohols. It is also found that high temperature, space velocity, H(2)/CO in feed gas and low pressure are preferential for light hydrocarbons and alcohols while against the chain propagation. The effect of space velocity on the product distributions especially on the light products is not obvious. It is noticed that low temperature, space velocity, H(2)/CO and high pressure lead to high contents of alcohols; high temperature, H(2)/CO and low space velocity lead to high contents of alkanes. The effect of pressure on the amounts of alkanes is not significant; high space velocity and low temperature, pressure, H(2)/CO are preferential for alkenes.
