Coal liquefaction support studies. Quarterly report, April--June 1976

A development program is being carried out to obtain information applicable to the SYNTHOIL process for converting coal to liquid fuel of low sulfur content. Information is presented on (1) the design of a calorimeter to measure heat of reaction of hydrogen with coal slurries, (2) the design of apparatus and calculations for measuring coefficients of heat transfer from SYNTHOIL process feed and effluent products to process vessel walls, (3) tests on the use of additives to facilitate the removal of solids from oil produced in coal liquefaction process, and (4) modifications of the design of a test unit for evaluating new catalysts for the SYNTHOIL process.
