Abstract

High activity of metal complex catalytic systems comprising nitrogenous bases and copper sulfates, acetates, and basic carbonate in oxidation of hydrogen sulfide and light mercaptans with atmospheric oxygen was established. Their activities are close to that observed for the chlorine-containing analogs, while no corrosion effect is exerted. An increase in the initial concentration of H₂S has negligible effect on its conversion rate. Mercaptans do not affect the H₂S oxidation rate, whereas an increase in the hydrogen sulfide concentration decelerates mercaptan oxidation. This is a diffusion-controlled reaction; hence, intensification of mixing of the catalyst with the hydrocarbons affords a 30–40% increase in the demercaptanization efficiency. The efficiencies displayed in demercaptanization processes by the catalytic systems and by the conventional scavengers neutralizing light sulfur impurities were compared.

用于氧化石油产品中硫化氢和硫醇的非腐蚀性金属络合物催化剂

摘要

建立了由含氮碱和硫酸铜、乙酸铜和碱式碳酸盐组成的金属络合物催化体系在用大气氧氧化硫化氢和轻硫醇中的高活性。它们的活性接近于含氯类似物的活性，而没有产生腐蚀作用。_{H 2} S初始浓度的增加对其转化率的影响可以忽略不计。硫醇不影响 H ₂S氧化速率，而硫化氢浓度的增加会减慢硫醇的氧化。这是一个扩散控制的反应；因此，加强催化剂与烃类的混合可使脱硫醇效率提高 30-40%。比较了催化系统和中和轻硫杂质的常规清除剂在脱硫醇过程中显示的效率。
