It is an efficient catalyst for removing mercaptan in light oil. Gasoline refined from sour crude oil contains higher mercaptan sulfur content.

mercaptan wrapped in fuel is malodorous and corrosive, which reduces the lead content of gas. except, mercaptan is also an oxidation initiator, which can promote the oxidation and condensation of risky components in fuel to gel, resulting in terrible garage balance of gasoline. cobalt phthalocyanine sulfonate is an powerful catalyst for disposing of mercaptan sulfur from heavy oil, and it has the identical effect. whilst in use, dissolve the catalyst in 10% alkali solution, heat it slightly for a time frame, and stir to dissolve it before use.
