Phthalocyanine Metal Macrocycles as a Nano-Catalyst for Purification of Hydrocarbon Raw Materials from Sulfur Compounds

Abstract

Pollution of hydrocarbon streams can be caused by hydrogen sulfide and mercaptans. Storage tanks and pipelines can also cause adverse effects on emissions. Therefore, demercaptanization and sulfur removal are ongoing research and debate topics. For the Merox® process, high pressures and temperatures are required. The development of new catalysts is of great interest. Metallophthalocyanine derivatives assist in removing crude mercaptants from hydrocarbon raw materials and increase productivity.
