Research results related to coal gasification and liquefaction are reported, including fundamental studies on the processes involved and the properties of the coal conversion products. Coal and various coal derived liquids are being extracted with a variety of solvents with the aim of separating, classifying and characterizing the products, using modern instrumental techniques to identify the chemical species. The possibility of converting synthesis gas to methanol or other hydrocarbons with C2 to C5 range is being studied as a means of providing a more convenient shipping alternative. Several studies involved catalysts, including the performance of the reaction involved over a range of conditions (particularly with respect to hydrogenation). The possibility of cracking the heavier oils from the solvent refined coal recycle to provide high grade gasoline was investigated. So far the conversion appears to be low. An experimental apparatus has been constructed for fluid dynamic and heat transfer studies involving gas-solids suspensions in vertical cocurrent flow. Some other work on aspects of coal gasification and liquefaction (involving coal feed variations (particle size, etc.), the catalyst, the residence time, etc.) are reported briefly. (LTN)
