Abstract

The invention provides a catalyst for producing BTX aromatic hydrocarbons by utilizing organic waste, a preparation method and application thereof, and a method for producing BTX aromatic hydrocarbons. First, a method for preparing a catalyst for producing BTX aromatic hydrocarbons from organic wastes is provided, comprising the following steps: 1) pyrolyzing the organic wastes to obtain semi-coke and volatile matter; 2) grinding the semi-coke and obtaining by gravity separation Carbon powder, the catalyst is obtained. After the carbon powder is loaded with active components, it is calcined and activated to obtain a catalyst loaded with active components. Secondly, the gas phase product volatiles or gasification tar produced by the pyrolysis of organic waste gas are catalytically reacted with the prepared catalyst or the catalyst loaded with active components to obtain low-boiling tar BTX aromatics, combustible gas and high-boiling oil. The present invention can directly turn organic wastes such as household waste into high-quality chemical products BTX aromatics, does not require valuable resources such as petroleum, methanol, ethanol, dimethyl ether or n-hexane, and reduces resource consumption.

Description

technical field

[0001] The invention belongs to the field of utilization of organic wastes, and in particular relates to a catalyst for producing BTX aromatic hydrocarbons by utilizing organic wastes, a preparation method and application thereof, and a method for producing BTX aromatic hydrocarbons. Background technique

[0002] Combustible organic wastes include plastics, paper, cloth, biomass, etc., and most domestic disposal methods are incineration or landfill. Incineration is easy to produce secondary pollution, while landfill wastes resources and causes more serious secondary pollution. Pyrolysis refers to the technology of heating waste to a certain temperature in the absence of oxygen to obtain gas-phase combustible gas, liquid-phase oily liquid and solid-phase semi-coke. Compared with direct incineration of waste, it has the advantages of high calorific value of gas-phase products, no hazardous wastes such as fly ash, and no dioxins. In addition, with the gradual ...
