摘要：
The process of demercaptanation of light hydrocarbon feedstock (butane - butene oil fraction) carried out with a new heterogeneous phthalocyanine catalyst (KS-2B) of the alkaline solution regeneration is described. The results of the catalyst operation (degrees of refining from the mercaptane S) are given. An increase in the service life of the alkaline solution upon using the KS-2B catalyst is noted. It is explained by the fact that during the regeneration of alkaline solution sulfinates present in small amounts are converted into water-soluble neutral products, and it prevents fast consumption of the alkali in the system, though the yield of disulfides are low.
