Title: The Innovative Contributions of Murray R Gray
Introduction
Murray R Gray is a notable inventor based in Edmonton, Canada. He has made significant contributions to the fields of chemical engineering and biotechnology, holding 2 patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is a process for the extraction of bitumen from oilsands. This innovative method allows for the cracking and full recovery of bitumen through light hydrocarbon extraction, following exposure to modified natural zeolite catalysts under cracking conditions. The recovered bitumen exhibits reduced viscosity and lower boiling point distributions. This effective cracking process using economical and readily disposable natural zeolites represents a significant advancement towards a waterless and environmentally friendly extraction method.
Another notable invention by Gray is a cell culture bioreactor designed for culturing living cells, particularly shear-sensitive cells. The bioreactor consists of a stationary vessel with opposite spaced walls inclined at an angle, forming upper and lower walls. Liquid culture medium and cell culture, such as hybridoma cells, are introduced into the vessel. Gas is introduced at the lower end of the vessel to create gas bubbles that travel upward along the upper wall, effectively circulating the cells and liquid medium. This design achieves bulk mixing and aeration while maintaining a significant degree of segregation between the upwardly traveling bubbles and the cells, thus avoiding unnecessary cell damage.
