Latest Patents
One of his latest patents is focused on the production of high purity olefins. This process involves converting an oxygenate feed to high purity olefins, such as polymer-grade propylene, at a temperature of about 450°C (842°F). The method utilizes a molecular sieve catalyst with a high preselected Si/Al₂ ratio, such as ZSM-5 or ZSM-48, or a preselected Si/Fe₂ ratio, such as FeZSM-5 or SAPO-34. Another significant patent addresses the acid extraction of molecular sieve catalysts to improve ethylene yield. This method enhances ethylene yield in the conversion of oxygenates to olefins by extracting molecular sieve catalysts with a mineral acid, which alters the crystallinity of the catalyst and improves yield.
