About Thomas D. Wheelock

Specific problems of environmental pollution have been addressed through the development of improved methods for removing sulfur and ash-forming mineral matter from coal and by the development of a method for regenerating calcium-based sorbents that are used to remove sulfur compounds from the products of coal gasification or coal combustion. This effort is being extended to the development of a combined catalyst and sorbent for use in steam reforming hydrocarbons to produce hydrogen.The research effort is based on an extensive background of experience gained by studying a number of potentially useful methods for cleaning and/or utilizing coal. These methods have included both chemical leaching and particle separation processes as well as coal gasification by means of a unique electrothermal fluidized bed reactor. The present effort is also based on experience gained in developing an unusual cyclic process for decomposing calcium sulfate in a two-zone fluidized bed reactor whereby the material is exposed alternately and repeatedly to reduction and oxidation at high temperature.
