Title: The Innovative Contributions of Bernard E. Weichman
Introduction
Bernard E. Weichman is a notable inventor based in Houston, Texas, recognized for his significant contributions to the field of oil shale recovery. With a total of five patents to his name, Weichman's work focuses on innovative methods for extracting valuable resources from oil shale, which is crucial for energy production.
Latest Patents
Weichman's latest patents include a "Method for in situ shale oil recovery" and an "Integrated in situ shale oil and mineral recovery process." The first patent outlines a method for processing oil shale ore by establishing underground stopes, rubblizing the remaining ore, and extracting it for further processing. This method ensures that the stope is maintained substantially filled with ore to provide lateral support and reduce the risk of collapse. The oil shale is then retorted through hot gas injection, allowing for the recovery of residual carbon as producer fuel gas.
The second patent describes a similar process but focuses on mineral-bearing oil shale ore. It involves the establishment of multiple underground stopes, extraction of nahcolite and oil shale fractions, and the recovery of valuable minerals like soda ash and alumina through leaching after retorting. This innovative approach enhances the efficiency of resource recovery from oil shale.
