Abstract

In a recent evaluation of developments in coal liquefaction technology, the removal of inorganic constituents during coal liquefaction has proven to be difficult. The separation of mineral matter, undissolved organic matter and the unliquefied coal has been identified as an unanswered critical technical problem in coal liquefaction or solvent refined coal processes (SRC). In this paper the author has briefly reviewed the separation methods and devices tried by several workers with some success. Work carried out on separation processes, especially on coal liquefaction and SRC processes in various countries have been briefly discussed. Work done at CFRI, Dhanbad on filterability f SRC has been described. Although similar separation has been examined using hydrocyclone and centrifuges, only pre-coat filtration was reported to reduce the sulphur and ash content to acceptable levels. However, the most used and best demonstrated method of accomplishing solids removal to date is filtration.
