Technical Field

Background
Waste plastics, rubber, leather, wood fiber and the like in the solid waste have great energy utilization value, and the high-efficiency recycling of combustible solid waste can be realized while pollution is strictly controlled by adopting a pyrolysis gasification technology. The pyrolysis gasification refers to a reaction process of utilizing the thermal instability of organic matters in the solid waste, and enabling the organic matters to be heated to be chemically decomposed in a pyrolysis reactor in an oxygen-deficient atmosphere, so that the organic matters are converted into storage energy mainly comprising combustible gas. The catalytic modification means that the pyrolysis gasification product is introduced into a catalytic reactor, and a proper amount of catalyst is added into the catalytic reactor, so that the pyrolysis gasification product further reacts, and combustible gas with higher quality is obtained.
The pyrolysis and gasification temperature of different substances in the solid waste is different, for example, the pyrolysis and gasification temperature of various plastics is as follows: performing primary pyrolysis on polyvinyl chloride at 450-600K, performing pyrolysis on polystyrene at 600-633K, performing pyrolysis on polypropylene at 630-670K, performing secondary pyrolysis on polyvinyl chloride at 630-670K, and performing pyrolysis on polyethylene at 670-770K; the pyrolysis temperatures of the various rubbers were as follows: the pyrolysis temperature range of the natural rubber is 600-730K, the pyrolysis temperature range of the styrene butadiene rubber is 560-763K, and the pyrolysis temperature range of the butadiene rubber is 647-770K. However, various components are mixed in the solid waste, so that after a heating curve of the pyrolysis gasification furnace is set in an experiment, some macromolecular products which are not completely pyrolyzed can be generated, the macromolecular products influence the quality and the heat value of the combustible gas, and by integrating a catalytic modification function, macromolecular substances with higher activation energy in the products can be promoted to generate more complete reaction, so that the quality of the combustible gas is further improved.
