Abstract
PURPOSE: To obtain gas suitable for use as city gas, by a method wherein impurities such as chlorine compd. and sulfur compd. present in gas obtd. by the thermal decomposition of a solid waste are removed, and the resulting gas is treated in a low-temperature steam reforming stage.
CONSTITUTION: A solid waste is supplied through a line 17 to a thermal decomposition furnace 11, and thermally decomposed at a temp. of 700W900°C. The resulting gas is supplied to the first- stage scrubber 22 where the gas is scrubbed with a washing having a pH of 8W9. Then the gas is scrubbed with a washing liquid having a pH of 10W11 in the second scrubber 23. The resulting gas is introduced into a gas-absorption tower 32 where the gas is contacted with an absorbing solution contg. a redox catalyst to desulfurize the gas. Then the gas is supplied to adsorption columns 34, 35 in which active carbon layers 36, 37 for high-boiling component adsorption are provided at the lower part and active carbon layers 38, 39 for low-boiling component adsorption are provided at the upper part. After removal of chlorine compd. and sulfur compd. in the adsorption columns, the gas is passed through a compressor 43 and a heating oven 44, and mixed with steam supplied from a line 45. The mixture. is supplied through a heating oven 46 to an adiabatic fixed bed reactor 47 where the mixture. is contacted with a low-temperature steam reforming catalyst 48. Then the produced gas is cooled in a condenser 50 to condense unreacted steam which is then separated and removed in a gas-liquid separator 51.
