经过对Fischer—Tropsch合成(简称F—T合成)产品分布和schulz—Flory方程的研究与分析,提出了对决定F—T合成产品分布的重要参数——链生长几率、链生长速率及链终止速率的直接计算方法。这些参数精确数值的获得,为深入理解F—T合成的本质、研究其反应机理以及提高产品选择性提供了可靠的科学依据。用10％Co/Al_2o_3做催化剂,在不同的空速、不同的原料气组成、不同的反应温度及不同载体上所作的F—T合成实验表明,理论计算值与实际实验值之间是非常吻合的。
After the research and analysis of product distribution and schulz-Flory equation of Fischer-Tropsch synthesis (referred to as F-T synthesis), we proposed some important parameters that determine the distribution of F-T synthetic products-chain growth probability, chain growth rate and chain termination Direct calculation of the rate. The accurate numerical values of these parameters provide a reliable scientific basis for further understanding of the nature of F-T synthesis, the study of its reaction mechanism and the improvement of product selectivity. The experiments of F-T synthesis with 10% Co / Al 2 O 3 as catalyst at different space velocities, different feed gas compositions, different reaction temperatures and different supports show that the calculated values are in good agreement with the actual experimental values of.
