[0093] Example 1 Production of bio-fuel or chemical raw materials, high calorific value gas or hydrogen and activated carbon by catalytic cracking of distiller's grains

[0094] Take the wet distiller's grains and dry them at 100°C; crush the dried distiller's grains to particles with a particle size of 300um to obtain dried distiller's grains; add 0.05 tons of industrial FH-UDS catalyst to 1 ton of dried distiller's grains, FH- UDS catalyst was developed by Fushun Petrochemical Research Institute and mixed evenly. After that, send it to the cracking tank, and pass nitrogen gas, after 10 minutes. Heating, the temperature of the system was raised to 500°C, and the pyrolysis was maintained at this temperature for 100 minutes. The pyrolysis steam is condensed in an ice-water bath to obtain crude product bio-oil and pyrolysis gas. The remaining residue is pyrolysis residue, and the mass of bio-oil, pyrolysis gas and pyrolysis residue is about 0.39 tons, 0.27 tons, and 0.33 tons ...

Abstract

The invention relates to a comprehensive utilization method of vinasse, and aims at mainly solving the technical problem that a novel method for processing vinasse is provided. The comprehensive utilization method of the vinasse disclosed by the invention mainly comprises the following steps: taking dried vinasse, crushing, and adding a catalyst to split, so as to obtain cracked steam and cracked residue; condensing the cracked steam to obtain bio-oil and a pyrolysis gas; adding a dehydrating agent to the bio-oil, and dehydrating to obtain biofuel oil. The bio-oil also can be used as a source of a series of important chemical raw materials; the pyrolysis gas is a combustible gas with a high calorific value which is obtained after carbon dioxide is removed; the pyrolysis gas also can be used as a source for obtaining hydrogen; the cracked residue can be directly used as activated carbon, a catalyst or a vector or metal components in the cracked residue are recovered. In addition, the residual residues are obtained, can be used as the activated carbon, and also can be used as fuel, so as to obtain white carbon black by combustion.

Description

technical field [0001] The invention relates to a method for comprehensive utilization of distiller's grains, and belongs to the field of comprehensive utilization of distiller's grains. Background technique [0002] As we all know, the winemaking industry around the world has developed rapidly. The prosperity of the winemaking industry has brought joy to people, but also brought worries and confusion to the society. On the one hand, various finished wines are continuously put on the market. The remaining distiller's grains and waste liquid are piled up like mountains, flooding, and these discarded distiller's grains seriously pollute the environment. [0003] In view of the above situation, relevant institutions and technical personnel at home and abroad have done some beneficial exploration and research on the comprehensive utilization of distiller's grains and waste liquid, for example, "the method of using distiller's grains to make activated carbon" described in CN88102...
