Problems solved by technology

[0016] However, in the preparation of bio-oil by high-temperature distillation of garbage, the bio-oil is generally separated from water first, and then the bio-oil is hydrogenated and upgraded. However, the bio-oil before hydrogenation and upgrading contains more phenols, aldehydes, Polar substances such as acids are difficult to separate, and complex separation processes are required to effectively separate them, resulting in complicated process procedures and high production costs
In the above literature and other prior art, there is a lack of a catalyst that can withstand high hydrothermal environment

Embodiment 1

[0063] The hydrogenation catalyst is prepared as follows: weigh a certain amount of Co(NO 3 ) 2 ·6H 2 O, add citric acid and deionized water to dissolve, make a solution with a concentration of 3.0mol / L, weigh a certain amount of zeolite beta and put it into a reaction vessel, pour the prepared solution into the reaction vessel, and place it with Heat in the constant temperature heating oil bath device of the stirrer, stir at 60-120°C for 1h-10h, then put it in a drying oven and dry at 100°C for 2h, then place the obtained catalyst precursor in a muffle furnace at 350°C Calcined for 3h, then switched to CS 2 In a mixed gas atmosphere of saturated steam and hydrogen, vulcanize at 60°C for 1.0 hour to prepare CoS / β zeolite; (2) Weigh a certain amount of precursor salt such as Ni(NO 3 ) 2 , Cu(NO 3 ) 2 , Pd(NO 3 ) 2 and citric acid, add deionized water to dissolve, stir evenly, and make a solution with a concentration of 0.5mol / L, weigh a certain amount of the CoS / β zeoli...

Embodiment 2

[0065] Domestic waste from the Wuluju Waste Compression and Transfer Station in Haidian District, Beijing was selected. The composition of the waste was tested and shown in Table 1 below:

[0066] Table 1: Composition of MSW

[0067]

[0068]

[0069] The above-mentioned garbage is subjected to high-temperature distillation carbonization through the following steps: loading the garbage into the garbage transportation device; passing the garbage transportation device through the high-temperature distillation carbonization device; taking out the gas stream from the upper part of the high-temperature distillation carbonization device; passing the gas stream in gaseous form Catalyst bed; condensing and separating the effluent from the catalyst bed to obtain liquid combustibles and water; obtaining charcoal from the waste transport unit passing through the high-temperature distillation carbonization unit. The high-temperature distillation carbonization device is heated by hig...

Abstract

The invention provides a garbage disposal catalyst with high-temperature water vapor stability. The catalyst is a beta zeolite-loaded cobalt-based catalyst. The catalyst has extremely good water vapor stability, so that the catalyst is especially conducive to hydroupgrading of high-steam content biological oil produced during high-temperature distillation carbonization of garbage.

Description

technical field [0001] The invention belongs to the technical field of catalysts, and in particular relates to a catalyst for garbage treatment with high temperature water vapor stability. Background technique [0002] Bio-oil crude oil is usually of poor quality and needs subsequent modification and upgrading to meet fuel requirements. Bio-oil upgrading mainly includes hydrodeoxygenation, catalytic cracking, catalytic reforming and catalytic esterification. Catalytic upgrading can change the composition of bio-oil and fundamentally change the quality of bio-oil. Key technologies such as yield and efficiency in production have yet to be broken through, and the development of high-efficiency catalysts will be the focus and difficulty of improving the quality of bio-oil in the future. [0003] At present, the annual output of domestic waste in my country is as high as 180 million tons, and the annual output of urban waste per capita is about 440 kg, and it is increasing rapid...
