catalysts and yields of the products are explored. It is shown that, in the СО/H2О system, the highest conversion of benzothiophene and dibenzothiophene is attained at a temperature of 380°С, a СО pressure of 5 MPa, and a СО/H2О molar ratio of 2. The introduction of alkyl substituents into a dibenzothiophene molecule causes a reduction in the rate of reaction that predominantly occurs via the hydrogenation
摘要不支持的Ni-Mo系硫化物催化剂的活性进行了研究在苯并噻吩和二苯并噻吩的温度范围340-380°С的加氢转化和以增加的ħ 2压力和СО/ H 2 О系统。通过TEM研究了油溶性前体(六羰基钼,环烷酸镍)的原位高温分解形成的分散催化剂的结构。的СО/ H影响2进行了探索О摩尔比,在系统中的水的质量含量,并且在催化剂和产物的收率的活性CO压力。它被示出的是,在СО/ H 2 О系统,苯并噻吩和二苯并噻吩的最高转化率达到380℃С,5MPa的压力СО的温度,和一个СО/ H2摩尔比为2。将烷基取代基引入二苯并噻吩分子中会导致反应速率降低,而反应速率的降低主要是通过芳香环的氢化而发生的。在H在氢化催化剂活性2压力和СО/ H 2 О系统是相当的。
