Coal Chemical Terminology
1 Scope
This document defines terms related to coal chemical processes, their English translations and definitions:
This document applies to relevant standards, documents, teaching materials, books and manuals:
2 Normative references
There are no normative references in this document:
3 Basic terms
3:1
coalchemicaltechnology
Process technology for producing various energy or chemical products using coal as raw material:
Note: Coal chemical technology generally includes two links: coal conversion and subsequent processing:
3:2
coal conversion coalconversion
The process of converting coal into gas, liquid and solid products mainly by chemical methods:
3:3
coal pyrolysis
Coal is continuously heated under different atmospheric conditions without air or without oxidant, and coal undergoes a series of physical changes at different final temperatures:
Chemical and chemical reactions, and the process of generating products such as gas (gas), liquid (tar), solid (semi-coke or coke):
Note: Coal pyrolysis can generally be divided into high temperature pyrolysis (about 900℃~1100℃), medium temperature pyrolysis (about 660℃~750℃) and low temperature pyrolysis (about 500℃~1100℃)
580°C):
3:4
coal gasification
Under certain temperature and pressure conditions, the process of converting coal into carbon monoxide and hydrogen-based gas with a gasification agent:
Note: Coal gasification mainly includes fixed bed, fluidized bed, entrained bed and other gasification processes:
3:5
coal liquefaction coalliquefaction
The process by which coal is converted into liquid products through a series of chemical processes:
Note: Coal liquefaction is generally divided into direct liquefaction and indirect liquefaction:
3:6
coal-based chemicals
Chemical products produced from coal:
3:7
coal-based poly-generation
Using coal as raw material, through the optimization and integration of multiple single technologies, it is a technical system that produces a variety of energy and chemicals:
