Description

Reaction device for catalytic cracking of tar by carbon-based catalyst

Technical Field

The utility model relates to a technical field is got rid of to tar, specifically is a reaction unit of carbon back catalyst catalytic cracking tar.

Background

With the rapid development of economy and the remarkable increase of human consumption level, the production amount of solid wastes increases year by year. The annual output of organic solid wastes represented by agricultural and forestry biomass wastes, sewage sludge, industrial organic solid wastes and the like exceeds 60 hundred million tons per year, and the method has the characteristics of large quantity, wide range and serious compound pollution. The organic waste has high organic matter content, is a potential resource, and can be recycled, so that the problem of resource shortage can be solved, the carbon emission can be reduced, and the global warming can be relieved.

From the perspective of sustainable development of the strategy of disposing domestic garbage, clean and efficient disposal of organic solid wastes should follow three major goals of reduction, harmlessness and recycling. With the exhaustion of fossil energy in the global scope, the environmental and ecological protection consciousness of the masses is gradually improved, the scientific technology in the ecological environment field is continuously improved, and the high-efficiency and clean household garbage thermal treatment technology is bound to become one of the optimal modes for treating urban solid wastes in the future. The domestic garbage thermal disposal mode is mainly divided into three technologies of incineration, pyrolysis and gasification. The gasification technology refers to a thermal conversion process in which organic solid waste is subjected to thermochemical reaction with certain gasification media under a high-temperature reducing atmosphere to generate combustible light gases such as CO, H2 and CH4, and has many advantages compared with a traditional garbage thermal disposal mode of incineration: (1) the emission level of the conventional pollutants is low; (2) the gasification technology obviously reduces the amount of discharged flue gas by adopting a relatively low excess air coefficient; (3) the gasification technology can convert the domestic garbage into diversified products such as combustible gas, liquid fuel, coke and the like, and realizes the diversified utilization of the solid waste.

Compared with coal gasification, organic solid waste gasification has high tar content, the prepared synthesis gas can not be directly used for fluidized bed methanation, gasification can maximize the conversion of organic solid waste into high-quality synthesis gas, the gasification can be used for methanation, but the unavoidable production of tar in the organic solid waste gasification process can not only meet the demand of synthesis gas high-valued on raw materials, but also can cause other problems, such as: (1) fouling filters and piping and deactivating downstream catalysts; (2) the tar energy accounts for 5-10% of the fuel gas energy, and if the tar energy is not utilized, energy waste is caused; (3) the tar can also bring the problems of phenol-containing waste water and foul smell, and seriously pollute the environment. Therefore, it is necessary to remove tar.

The existing tar removal catalyst, such as a nickel-based catalyst with relatively high activity, an alkali metal catalyst, a natural ore catalyst and the like, can be quickly deactivated in the environment of water and oxygen in the process and is difficult to recycle, while the semi-coke catalyst can also face the problem of deactivation, but the energy after the deactivation can be recycled through gasification reaction, and the catalyst has wide sources and low cost and is suitable for the process conditions. Because the catalyst is consumed in the reaction too fast, the existing catalytic reaction device can not realize that the deactivated catalyst is discharged from the reactor and simultaneously fresh catalyst is added, so the catalytic reactor needs to be designed to realize the process.
