Problems solved by technology

[0008] CN103319102A discloses a method of using furfural waste residue as fuel, but it directly burns it directly, and does not make full use of a large amount of organic matter in it, resulting in low energy utilization rate
Some are disposed of by stacking or digging pits and dumping, which not only wastes human and financial resources, pollutes the environment, but also takes up a lot of land, making these low-quality biomass energy go to waste
[0009] CN103316897A discloses a treatment method for solid waste through digestion, granulation, sintering, and blending. This method cannot remove harmful substances that cannot be decomposed in the process, but instead forms a cumulative
CN1454721A discloses a treatment method for oily waste residue, but it only separates the oil and does not substantially treat the residue
Solid waste can easily cause soil and air pollution, and even more seriously, it will cause harm to the human body

Abstract

The invention discloses a method for preparing synthesis gas from an organic dissolvant and a biomass residue, wherein the method comprises the steps of pretreatment, slurry preparation, gasification and the like. The characteristics of high calorific value and organic matter cosolvency of the abandoned organic dissolvant and low mineral content, low ash fusion point and rich C and H elements of the biomass residue are fully used, and the waste harmless treatment and resource transfer application are realized. The calorific value of the prepared slurry is 10%-70% higher than that of 60% water coal slurry having the same mass as the slurry, and the method can be used in preparation of the synthesis gas with CO and H2 as main components through a wet entrained-flow bed gasification process.

Description

【Technical field】 [0001] The invention belongs to the technical field of coal gasification slurry preparation. More specifically, the present invention relates to a method for the production of synthesis gas from organic solvents and biomass residues. 【Background technique】 [0002] With the rapid development of my country's pharmaceutical industry, the pollutants produced in the production process have also caused great pressure on the environment. How to treat the waste generated in the pharmaceutical process in a harmless manner is an important problem to be solved urgently. The waste solvent produced in the pharmaceutical process is an organic substance rich in C and H, which has a high calorific value, and direct disposal is not conducive to resource recycling. Solvent recovery is an important link in the production of pharmaceutical companies, but its recovery rate needs to be improved, and its composition is complex. Waste organic solvents produced by chemical comp...
