Abstract
The invention belongs to the technical field of coal desulfurization, and provides a coal desulfurization technology. According to the coal desulfurization technology, biomass is added in the coal for co-pyrolysis between the biomass and the coal. The method of the coal desulfurization technology comprises the steps of S1, selecting a material; S2, smashing; S3, exhausting; S4, increasing temperature; S5, reacting; S6, cooling; S7, collecting. The added biomass makes the precipitation of H2S and COS advance. The biomass is beneficial to removal of sulfur and nitrogen in the coal pyrolysis process, can stop cohering among particles in the pyrolysis process of the strong cohesive coal, and promote sufficient pyrolysis and desulfurization of the coal. The addition of the biomass increases desulfurization degree and obtains high heat value semicoke, and rich alkali metal contained in the biomass can generate catalytic action in the gasification process so that remarkable reduction of gasification reaction activation energy of pyrolysis char can be caused. On one hand, the gasification reaction of the pyrolysis char is obviously higher than reactivity of coal char, on the other hand, the efficiency of the coal desulfurization is effectively improved, and the influence of the coal pyrolysis gasification process on the environment is reduced.

Dye one just can form " acid rain " while severe corrosion equipment.The latter causes forest decay, the ecosystem on a large scale
The one of the main reasons of destruction, the agriculture underproduction, building corrosion and many diseases.But from from the perspective of coal resources, sulfur-bearing
Sulphur coal of the amount more than 2% accounts for 30% or so of coal resources proved reserves, occupies critical role.Therefore sulphur in coal is understood
Sulphur removing sulfuldioxide in the effective coal of occurrence patterns, exploiting economy, the quality to improving coal, realizing the efficient clean utilization of coal has
Very important realistic meaning.
The removing of sulphur in coal is always the important topic of coal chemistry research, and many methods have been used to the removing of sulphur in coal.
Wherein, as coal clean and effective using important composition portion in one of effective means and the coal process such as gasification, burning and liquefaction
Point pyrolysis, cause the extensive concern of people because it has certain desulfidation.In pyrolytic process, inorganic sulfur and part have
Machine sulphur can be with the easy H for recycling2The form of S enters gas phase, and then is effectively removed.However, in more gentle heat
Under the conditions of solution, pyrolysis of coal desulfuration efficiency is relatively low, has some scholars to enter with biomass copyrolysis behavior to coal both at home and abroad at present
Go compared with system research, the burnt gasification activity of the transition behavior and copyrolysis to sulphur during copyrolysis has been also carried out tentatively examining
Examine.The content of sulphur and the survey of composition in the gas-solid-liquid three-phase product that result of study focuses mostly on after to coal and biomass copyrolysis
Examination, catalysis of the alkali metal to the burnt gasification reaction of copyrolysis in the impact and biomass after analysis addition biomass to sulphur transition
Effect.
