Title: David A. Culver: Innovator in Ethanol Purification and Olefin Production
Introduction
David A. Culver is a notable inventor based in Salem, NJ (US). He has made significant contributions to the field of chemical engineering, particularly in the processes of ethanol purification and the production of α-olefins. With a total of 3 patents to his name, Culver's work has had a meaningful impact on industrial practices.
Latest Patents
Culver's latest patents include a process for providing ethanol and a process for producing α-olefins. The ethanol purification process involves boiling a degassed beer feed in a pre-boiler to create a vapor by-pass fraction. This innovative method allows for the rectifier column's capacity to be utilized more efficiently by incorporating ethanol-water vapor and condensate streams that do not originate from the beer column. The α-olefin production process utilizes a modified plug flow reactor system, where ethylene is oligomerized using an iron complex catalyst. This reactor is designed to add the catalyst at multiple points along its length, optimizing the reaction based on the catalyst's half-life.
