Dynamic characteristics of sulfur release during burning processes of coal liquefaction residuals have been studied. 研究了煤液化殘渣燃燒過(guò)程中硫動(dòng)態(tài)析出特性。
Coprocessing can be considered as a transitional technology between heavy resid upgrading and coal liquefaction. 煤油共煉可以看作是重質(zhì)渣油提質(zhì)和煤液化之間的過(guò)渡技術(shù)。
The problem was one of liquefaction of the sandy soil. 問(wèn)題是沙質(zhì)土壤的液化作用。
Mainly on the basis of microscopic investigation into the residual materials,the liquefaction behaviour of each maceral group is examined. 對固體殘渣進(jìn)行了顯微研究，討論了各種煤巖組分的液化性能。
