TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The isolated contaminants are at least one of chlorine, mercury, sulfur, selenium or arsenic.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The kiln further comprises: means for rotating the inner core of the kiln, where the inner core is positioned concentrically within the stationary kiln outer shell; thermal sensors located between the kiln inner core and the kiln outer shell; a first connective duct, where the one end of the duct is affixed to the water cleanup station, and the opposite end is affixed near the proximal end of the kiln; and a screw drive at the distal end of the outer kiln shell, where the screw drive comprises means for ejecting solid material from distal end of the kiln. The system further comprises a second duct, where one end of the second duct is affixed to the wet scrubber, and the opposite end of the second duct is affixed near distal end of the kiln. The kiln comprises: an airlock at the proximal end of the kiln, where the airlock serves as the input port for the coal and biomass from the hopper; and a steel helical rail fixedly attached to inner surface of the inner core of the kiln. The outer shell of the kiln further comprises a set of coils, fixedly attached to the outer surface of the kiln shell with means for controlling the temperature of the kiln. The coal sizing tool comprises a proximal open end container and a distal open end, further comprising a chute fixedly attached to it, and further comprising a centrally located piston, where one end of the piston is fixedly attached to a perforated block within the container, and the opposite end of the piston is located exterior to the container. The opposite end of the sizing tool piston is connected to a motor, where the motor comprises means for moving piston and block in a vertical oscillatory motion. The coal sizing tool further comprises a conveyor belt positioned near the bottom of the coal sizing tool container, where the belt comprises means for moving the coal from the proximal to the distal end of the sizing tool. The vertical motion of the piston crushes the coal to a preferred volume of 0.25-10 cm3. The biomass sizing tool comprises a container with a proximal open end and a distal open end with a chute fixedly attached to the distal end, and further comprising a centrally located piston, where the one end of the piston is connected to a block within the container, and the block is fixedly attached to a set of cutting blades. The opposite end of the piston is positioned exterior to the container, where the opposite end is fixedly attached to a motor, and the motor comprises means for moving the piston and blades in a vertical oscillatory motion. The biomass sizing tool further comprises a conveyor belt positioned near the bottom of the sizing tool for moving the biomass from proximal to distal end of the sizing tool. The gasifier and steam generator are connected by duct, where the steam from the steam generator is directed into the gasifier.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The coal and biomass enter the kiln from the hopper fixedly attached to the proximal kiln end, where the coal and biomass exit the kiln at the kiln distal end. The temperature near the proximal end of the kiln is maintained at 125-200 degrees C, and the distal end temperature at 450-500 degrees C. The vertical oscillatory motion of the piston and cutting blades results in cuts to the biomass exiting the sizing tool with a preferred volume of 0.25-40 cm3. The gasifier receives heated coal (defined as char) from the distal end of the kiln and gaseous hydrocarbons from the wet scrubber, where the gasifier and kiln are fixedly attached by two open flanges, with opposite end of each flange fixedly attached to the distal end of kiln and proximal end of gasifier. The method of pre-processing coal and biomass, comprises transferring of heated biomass and heated coal (char) from the distal end of the kiln to the gasifier and further transferring the hydrocarbons from the wet scrubber to the gasifier, where the gasifier comprises means for further processing the heated coal, heated biomass and hydrocarbons into high caloric fuels.
