随着我国石油化学工业的发展,作为石油化学加工的主要原料之一的轻质油品产量将日益增长。在石油化学加工中,通常对原料含硫量有严格的要求,以防止发生催化剂中毒,如近年发展的双金属铂重整催化剂要求原料含硫量为1ppm以下;用于生产合成氨或甲醇原料气的蒸汽转化镍催化剂,则要求原料含硫量在0.2-0.5ppm。为了鉴定原料油的净化程度,必须建立相应的分析鉴定方法。还在1941年,Schreter就提出设想:根据骨架镍或称拉内(Raney 镍)可以和所有的有机化合物的硫定量结合的性质,可用它作为定量测定硫方法的基础。等应用这个反应于分
With the development of China’s petrochemical industry, light oil production as one of the main raw materials for petrochemical processing will increase day by day. In petrochemical processing, the sulfur content of raw materials is usually stringent requirements to prevent the occurrence of catalyst poisoning, such as the development of bimetallic platinum reforming catalyst requires the raw material sulfur content of 1ppm or less; for the production of ammonia or methanol feed gas Of the steam conversion of nickel catalyst, the raw material required sulfur content of 0.2-0.5ppm. In order to identify the degree of purification of raw oil, it is necessary to establish a corresponding analysis and identification methods. In 1941, Schreter also proposed that the basis for the quantitative determination of sulfur based on the quantitative binding of sulfur to all organic compounds, based on framework nickel or Raney nickel, may be used.
