Title: Clive Griffiths: Innovator in Selective Hydrogenation
Introduction
Clive Griffiths is a notable inventor based in Wilmslow, GB. He has made significant contributions to the field of chemical engineering, particularly in the area of selective hydrogenation processes. His innovative work has led to the development of a patented process that enhances the efficiency of converting alpha-methyl-styrene to cumene.
Latest Patents
Clive Griffiths holds a patent for the "Selective hydrogenation of alpha-methyl-styrene to cumene." This process involves a two-catalyst system where a crude cumene feed stream containing up to 10% alpha-methyl-styrene (AMS) by weight is introduced into the first reaction zone. In this zone, the feed is mixed with hydrogen in a catalyst bed containing nickel, achieving a conversion rate of 70 to 95 percent of AMS to cumene. The cumene and remaining AMS are then separated from hydrogen in a liquid take-off tray. The effluent from the first reaction zone is sent to a second reaction zone, where it is mixed with hydrogen gas in a noble-metal catalyst bed to convert any remaining AMS to cumene. The final product, cumene, can be collected and either resupplied to the hydrogenation reactor or used as feed for a phenol synthesis loop.
