- Result showsthat there is a better relation among coal conversion,H/C atomic ratio and maceralin the coal.
- However, either coal conversion or acetylene yield grew downwards as the feedstock rate was increased.
- The coal conversion technologies that come to dominate will be those that can meet the objectives of climate change mitigation at the least cost.
- The analytical approaches and the identifications of the compound of phenols,which are produced from coal conversion have beem summed up.
- Active bauxite,silicon dioxide,diatomaceous earth and ash have been found suitab le for alkali removal from hot flue gas in a coal conversion system.
- It is found that if the hydrocracking catalyst and the hydrorefining catalyst are used in ratio of 1:1, both high coal conversion and oil yield can be obtained, and the hydrogen consumption is low.
