Description
Technical Field
The invention belongs to the field of energy utilization, and particularly relates to a solid organic matter pyrolysis gasification coupling reforming purification reactor.
Background
When solid organic matters such as coal, biomass, municipal solid waste and the like are pyrolyzed under different reaction conditions, gas, liquid and solid three-phase products are generated. The gasification process is one of the most promising technologies for the production of synthesis gas and subsequent synthetic transformations, called indirect liquefaction. Wherein gasification technology is the basis and key for indirect liquefaction.
The gasification technology can be classified into a gasification technology using a gasifying agent and a gasification technology not using a gasifying agent according to whether a gasifying agent is used. Gasification using a gasifying agent may be classified into air gasification, oxygen gasification, steam gasification, carbon dioxide gasification, mixed gasification, and the like. It has been found that the gasification reaction process using the gasifying agent is a complex multi-component and multi-type chemical reaction system including oxidation reaction, reduction reaction, and cracking of solid materials. Since the gasification reaction is generally an endothermic reaction, sufficient heat must be provided to maintain the reaction in progress, the gasifying agent is typically selected to include air or oxygen. Air is used as a gasifying agent, and because the air contains a large amount of nitrogen, the heat value of the synthesis gas in the product is low, and the subsequent separation cost is high; the use of oxygen as the gasifying agent requires the addition of a set of air separation equipment. The gasification reaction is carried out under the condition of complete oxygen-free condition, and has the advantages of high heat value of products and simple reaction process, but how to provide an external heat source becomes a key problem, so the design of a gasification reactor and a reaction process becomes important.
The gasification reactor is mainly divided into a fixed bed gasification furnace and a fluidized bed gasification furnace. The fixed bed gasification furnace can be divided into a downdraft type, an updraft type, a horizontal suction type, a open center type and the like according to different gas outlets and furnace type structures, and has the advantages of simple structure, firmness, durability, convenient and reliable operation and low operation and investment cost; the method has the defects that the internal reaction process is difficult to control, the heat transfer and mass transfer are poor, tar and bridging are easy to generate, the production strength is low, and the method is not suitable for the requirement of large-scale development. The fluidized bed gasification furnace can be divided into a bubbling fluidized bed, a circulating fluidized bed, an entrained flow bed and the like according to the fluidization state, and has the advantages of uniform heat and mass transfer, high gasification reaction speed, high carbon conversion rate and easy industrial amplification; the defects are that the equipment structure is complex, the fixed investment is large, the raw materials need to be crushed and refined, the ash content in the combustible gas is high, and tar exists.
The main obstacle currently limiting the development and industrialization of gasification technology is the elimination of by-product tar. The presence of tar is prone to plugging, corrosion and equipment damage to the gasification system, leading to deactivation of downstream catalysts, serious environmental pollution, and the like.
