Latest Patents
Among his noteworthy patents, two stand out for their ingenuity and potential impact on energy efficiency:
1. **Method for Combined Cycle Electrical Power Generation** - This patent discloses a method for generating electrical power using an electrical generator driven by a gas turbine. The gas turbine is powered by two gaseous products derived from a coal gasification process. The first gaseous product is generated with hot char through the reduction of a coal/water slurry in a gasifier, while the second results from the oxidation of the hot char in a combustor. This innovative approach aims to enhance the efficiency of electrical power generation.
2. **Gasification Process for Carbonaceous Materials** - This patent details a coal gasification process where two portions of heat transfer material are introduced into a reaction vessel at varied locations and temperatures. In this system, steam ascends through the vessel to interact with the carbonaceous material, producing hot char and a gaseous product. The necessary heat for the gasification reaction is supplied by both portions of heat transfer material, while cooling of the hot char and gaseous product is achieved by contact with the first portion of heat transfer material.
