His work has implications for the production of various chemical compounds used in numerous industries.
Latest Patents
John R Green holds a patent for an aromatic alkylation process. This innovative process involves contacting the alkylation product with a purification medium in a liquid phase pre-reaction step to remove impurities and form a purified stream. The purified stream can then be further processed by liquid phase transalkylation to convert the polyalkylated aromatic compound into a monoalkylated aromatic compound. The process utilizes a large pore molecular sieve catalyst, such as MCM-22, as the purification medium due to its high reactivity for alkylation, strong retention of catalyst poisons, and low reactivity for oligomerization under pre-reactor conditions. This method effectively removes olefins, diolefins, styrene, oxygenated organic compounds, sulfur-containing compounds, nitrogen-containing compounds, and oligomeric compounds.
