Latest Patents

Tyagi's latest patents include a process for the fixed bed sweetening of petroleum distillates using halogenated metal phthalocyanine as a catalyst. This innovative process involves impregnating the catalyst on an activated charcoal bed by circulating an alcoholic alkaline solution through the charcoal until a colorless effluent is obtained. The petroleum distillate is then passed through this catalyst-loaded charcoal bed along with air or oxygen, under specific temperature and pressure conditions, to achieve a low mercaptan level in the petroleum distillates. The alkaline solution used can be methanolic or ethanolic sodium hydroxide, while the halogenated metal phthalocyanine catalyst is selected from dichloro cobalt phthalocyanine and dibromo cobalt phthalocyanine. The petroleum fractions targeted by this process include diesel, kerosene, and FCC gasoline.

Another significant patent by Tyagi is for the preparation of a novel catalyst useful for sweetening sour petroleum distillates. This invention aims to enhance the efficiency and effectiveness of the sweetening process, contributing to the overall improvement of petroleum product quality.
