Introduction
Standard Overview
GB/T 36562-2018 National Standard of the People's Republic of China "Mixed Aromatics from Direct Coal Liquefaction" specifies the terms and definitions, technical requirements, test methods, inspection rules and safety requirements for mixed aromatics produced by direct coal liquefaction.
Background of Standard Formulation
With the adjustment of the global energy structure and the improvement of environmental protection requirements, the coal chemical industry has gradually become an important energy pillar industry in my country. The direct coal liquefaction process is an important technical path for converting coal into liquid fuel, and mixed aromatics, as its important product, are widely used in the petrochemical industry.
Comparison of standard frameworks
| Dimensions | GB/T 36562—2018 | Comparison standards |
|---|---|---|
| Technical requirements | Distillation range, total aromatics, benzene and other content limits | GB/T 6536 (Distillation characteristics) |
| Test methods | SH/T 0714 (Gas chromatography) | GB/T 8017 (Determination of vapor pressure) |
| Safety requirements | Hazard classification of flammable liquids | GB 30000.7—2013 |
Explanation of professional terms
Direct coal liquefaction: The process of coal reacting with a catalyst to produce liquid fuel under high temperature and pressure conditions.
Mixed aromatics: Products containing a variety of aromatic hydrocarbons obtained by catalytic reforming and aromatization after direct coal liquefaction.
Distillation range: Indicates the evaporation characteristics of oil products. The initial distillation point and the final distillation point indicate the temperature at which the oil product starts and ends evaporation, respectively.
Implementation suggestions
1. Strictly control the quality and technical parameters of coal during the production process to ensure that the product quality of mixed aromatics meets the standard requirements.
2. Regularly calibrate the testing equipment and instruments to ensure the accuracy and reliability of the test method.
3. It is recommended to use an online monitoring system to monitor key indicators (such as temperature, pressure, etc.) in the production process in real time.
