TECHNOLOGY FOCUS - CHEMICAL ENGINEERING - Preferred Process: The synthesis gas from the gasification unit is cooled in a heat exchanger (32) prior to entering the interface zone. The synthesis gas from the getter bed is rapidly quenched to a temperature in the condenser to slow down recombination reactions. The synthesis gas from the condenser is continuously monitored to determine its fuel cell poisoning characteristics by passing a small slip stream of the cooled synthesis gas to a fuel cell tester stack having sacrificial fuel cell electrodes. The synthesis gas is continuously monitored during the operation of the process to prevent damage to the fuel cell from harmful materials selected from the group consisting of poison, corrosive materials, and/or particulate materials. The continuously monitored synthesis gas during the operation of the process is carried out by passing a small slip stream to an on-line process gas chromatograph for detection of light gases and sulfur-containing, chlorine-containing, and nitrogen containing organic materials. The synthesis gas from the interface zone passes to a Fischer Tropsch synthesis reactor system for producing a high carbon content compound. The Fischer Tropsch synthesis reactor converts the synthesis gas into paraffin wax. Light gases from the Fischer Tropsch synthesis reactor are recycled back to the gasification unit. The interface zone is passed to a pressure swing absorption unit to convert the synthesis gas. The hydrogen from the pressure swing absorption unit and carbon dioxide are recycled back to the gasification unit to adjust the hydrogen/carbon monoxide ratio for optimum utilization in the Fischer Tropsch synthesis reactor system.    TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Apparatus: The heat exchanger is used to preheat the greenhouse gas stream to the gasification unit. The high temperature filter removes particulate matter from the synthesis gas. The getter bed reactor removes sulfur-containing light hydrocarbons by a reaction with a bed material. The gasification unit is a single duplex rotary kiln having a primary region having a hollow flight screw to process the solid waste and a second region having conductively heated annular surfaces to heat the gases to 700-1600degreesC. The high temperature filter is a high efficiency particulate air filter (HEPA) and a guard bed to further protect the fuel cell. The high temperature filter contains a HEPA filter and a guard unit to protect the Fischer Tropsch catalyst.
