TECHNOLOGY FOCUS - CERAMICS AND GLASS - Preferred Component: The cracking reactor is mobile bed cracking furnace or fluidized bed cracking furnace made of metallic material or ceramic material. The hydrogen catalyst is cobalt, molybdenum, nickel or tungsten, or any one of platinum or rhenium.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The fuel gas is carbon monoxide obtained by gasifying the medium thermal-value gas and the cracking products generated by cracking of the biomass. The biomass is agricultural straw and wood. The agricultural straw includes maize straw, cotton straw, peanut shell, and soybean straw. The wood includes trees and wooden meal and/or sawdust. Preferred Process: The cotton straw is used as raw material, and having grain size of less than 5 mm and water content of less than 15% after cracking. The raw material is put into the mobile bed cracking furnace at 650 degrees C at a feed speed of 1 t/hour to have cracking reaction to generate charcoal and oil gas with carbon dust. Charcoal (350 kg) is produced per hour. The charcoal (50 kg) enters gasifier (7) from the lower gas outlet to react with air at 850 degrees C to generate carbon monoxide. The slag after the gasification is discharged from the lower slag outlet and used together with the pyroligneous liquid as raw materials of organic fertilizer. Carbon (300 kg) is obtained. Oil gas (650 kg) takes the dust to pass through deposition chamber (2), cyclone separator (3), and net filter (4) in sequence at 270 degrees C to remove the dust and enters fractionating tower (5) to fractionate. The top of the tower is at 30 degrees C. The bottom of the tower is at 280 degrees C. The pyroligneous liquid outlet is at 95 degrees C. Medium thermal-value gas (367.5 kg/hour), pyroligneous liquid (200 kg/hour), and wood tar (kg/hour) are obtained by the fractionation. The wood tar enters the hydrogenation reactor (6) to have hydrogenation by hydrogen catalyst at 350 degrees C under 8MPa. Volume ratio of hydrogen and wood tar is 1000-10000:1. Hydrogenation product (48 kg/hour) is generated by the hydrogenation. It is fractionated to obtain mixture of (kg/hour) liquid gas (10), gasoline (12), and diesel fuel (26). Sawdust is used as raw material, and has grain size of less than 1 mm and water content of less than 15% after cracking. The raw material is put into the mobile bed cracking furnace at 600 degrees C at a feed speed of 1 t/hour to have cracking reaction to generate charcoal and oil gas with carbon dust. Charcoal (320 kg) is produced per hour. Charcoal (80 kg) enters the gasifier from the lower gas outlet to react with air at 1000 degrees C to generate carbon monoxide. The slag after the gasification is discharged from the lower slag outlet and used together with the pyroligneous liquid as raw materials of organic fertilizer. Carbon (240 kg) is obtained. Oil gas (600 kg) takes the dust to pass through the deposition chamber, cyclone separator, and net filter at a constant temperature of 300 degrees C to remove the dust and enters the fractionating tower to fractionate. The top of the tower is at 25 degrees C. The bottom of the tower is 300 degrees C. The pyroligneous liquid outlet is at 85 degrees C. Medium thermal-value gas (290 kg/hour), pyroligneous liquid (180 kg/hour), and wood tar (100 kg/hour) are obtained by the fractionation. The wood tar enters the hydrogenation reactor to have hydrogenation by hydrogen catalyst at 430 degrees C under 5 MPa. Volume ratio of hydrogen and wood tar is 1000-10000:1. Hydrogenation product (900 kg/hour) is generated by hydrogenation. It is fractionated to obtain mixture of (kg/hour) liquid gas (20), gasoline (30), and diesel fuel (40). Peanut shell is used as raw material with grain size of less than 7mm and water content of less than 15% after cracking. It is put into the mobile bed cracking furnace at 700 degrees C at a feed speed of 1 t/hour to have cracking reaction to generate charcoal and oil gas with carbon dust. Charcoal (650 kg) is produced per hour. Charcoal (150 kg) enters the gasifier from the lower gas outlet to react with air at 1200 degrees C to generate carbon monoxide. The slag after the gasification is discharged from the lower slag outlet and used together with the pyroligneous liquid as raw materials of organic fertilizer. Carbon (240 kg) is obtained. Oil gas (600 kg) takes the dust to pass through the deposition chamber, cyclone separator, and net filter at 350 degrees C and enters the fractionating tower with top at 15 degrees C, bottom at 400 degrees C, and pyroligneous liquid outlet at 92 degrees C. Medium thermal-value gas (82.5 kg/hour), pyroligneous liquid (200 kg/hour), and wood tar (50 kg/hour) are obtained by the fractionation. The wood tar enters the hydrogenation reactor to have hydrogenation by hydrogen catalyst at 470 degrees C under 18 MPa. Volume ratio of hydrogen and wood tar is 1000-10000:1. Hydrogenation product (48 kg/hour) is generated by the hydrogenation. The hydrogenation product is fractionated to obtain mixture of (kg/hour) liquid gas (10), gasoline (12), and diesel fuel (26).
