This paper describes the principle of low-pressure methanol synthesis , low pressure associated with a single alcohol alcohol process characteristics, the major domestic methanol synthesis reactor , methanol synthesis catalyst development history and development direction. Describes the factory 200,000 tons / year methanol plant low coal process , C307 type methanol synthesis catalyst physical and chemical properties , quality indicators , filling and restore . Analysis of the operating conditions , such as temperature , pressure, space velocity , the hydrogen to carbon ratio , inert gases , CO2 content, the methanol content in the gas into the tower for methanol synthesis . 200,000 t / a methanol synthesis reactor using adiabatic - shell composite tube fixed bed catalytic reactor , filling C307 type methanol synthesis catalyst 63.5 tons , the actual running 53 months, methanol, 818,000 tons crude communism ( 761,000 tons of refined methanol ) The average daily production of crude methanol 549 tons , the highest crude methanol production amounted to 672 tons , per unit volume of catalyst production reached 18,000 tons of refined methanol / m3. Industrial production showed that methanol synthesis reactor temperature stable , easy to control , less impurities in the crude methanol .
