Nickel–tungsten sulfide catalysts for the hydrogenation of aromatic hydrocarbons have been prepared by the in situ decomposition of an oil-soluble tungsten hexacarbonyl precursor in a hydrocarbon feedstock using oil-soluble nickel salt nickel(II) 2-ethylhexanoate as a source of nickel. The in situ synthesized Ni–W–S catalyst has been characterized by X-ray photoelectron spectroscopy. The activity of
通过使用油溶性镍盐2-乙基己酸镍(II)镍(II)原位分解烃类原料中的油溶性六羰基钨前驱物,制备了用于芳烃氢化的镍-钨硫化物催化剂。原位合成的Ni–W–S催化剂已通过X射线光电子能谱进行了表征。在间歇式反应器中,在350℃的温度和5.0MPa的氢气压力下,在双环芳烃的氢化和二苯并噻吩的转化中,已经研究了所得催化剂的活性。结果表明,最佳的W:Ni摩尔比为1:2。以高硫和芳烃含量的原料进行加氢精制为例,
