Latest Patents

Usman Ahmed holds a patent for a method of in-situ retorting of carbonaceous material. This method involves a two-phase process designed to recover carbonaceous material contained within typical subterranean tar sand formations. The first phase includes the formation of conventional arrays of in-seam ducts and the positioning of heating devices to heat a section of the formation. This process is controlled to provide heat without burning the carbonaceous material, resulting in a quasi-stable zone of pyrolysis. This zone thermally cracks the carbonaceous material, producing various organic liquid oil fractions and derived condensible vapors. The second phase involves burning a residual coke layer formed during pyrolysis by introducing a combustion-supporting gas, which elevates the temperature and allows for continued withdrawal of the products.
