Figure A5. Syntec Biofuel, Inc., Technology Syntec Technology ©2006, Syntec Biofuel Inc. Thermogenics, Inc., Albuquerque, New Mexico Organizational Background–Thermogenics is a privately held corporation specializing in development of the company's patented gasification system. The company has been financed by private sources as well as U.S. DOE. Technology Characteristics–The Thermogenics technology, illustrated in Figure A6, relies on an air blown gasification technology. The gasifier converts cellulosic feedstock into synthesis gas that is cleaned with an electrostatic precipitator, and then cooled. The clean syngas can then be used for the production of mixed alcohols. Development Status - Feedstocks that have been tested or considered include: sorted municipal and commercial waste, shredded paper, wood waste, dewatered sewage sludge, scrap tires, agricultural waste, automobile shredder "fluff", paint sludge, oil field wastes and hydrocarbon contaminated soils Future Plans–The Company has partnered with Power Energy Fuels Inc. to provide the alcohol processing equipment. 74
Figure A6. Thermogenics, Inc., Technology ThermoChem Recovery International, Inc., Baltimore, Maryland Organizational Background–ThermoChem Recovery International, Inc. (TRI) was founded in 1996 as a licensee of proprietary technology developed by MTCI. The technology includes designs applicable to an integrated biomass biorefinery. TRI has partnered with a number of organizations to further develop their technology. Some of their partners include: Brigham Young University; North Carolina State University, University of Utah, US Department of Energy, Office of Energy Efficiency and Renewable Energy; Center for Technology Transfer, Inc.; American Forest and Paper Association and TAPPI. Technology Characteristics– TRI’s patented technology, shown in Figure A7, is known as the PulseEnhanced steam reforming gasification system, where the feedstock reacts in a gasifier with steam and oxygen at a high temperature and pressure in a reducing (oxygen-starved) atmosphere. This process produces a medium-Btu syngas comprised primarily of hydrogen, carbon monoxide, and smaller quantities of carbon dioxide and methanol. This syngas can be used as a substitute for natural gas or as a feedstock for various biofuels and other products, including ethanol, methanol, biodiesel and acetic acid. A unique feature of the technology is an indirect heating method using modular pulsating heaters in a steam-driven bubbling fluid bed vessel. The system simultaneously employs a water-gas shift reaction to produce additional hydrogen and carbon dioxide. The hot syngas leaves the gasification chamber and is passed through cyclones to remove particulate matter, 75
