A novel reactor system for studying the kinetics of coal liquefaction and related processes at very short reaction times

Abstract

Publisher Summary This chapter discusses the reactor system for studying the kinetics of coal liquefaction. Direct-coal liquefaction is generally run in the range of 350–450 °C at over 7 MPa. The heat capacity of experimental equipment is large compared to that of the sample being studied. This heats up and cools down the reactor system compared to the actual reaction times for many reactions. A number of workers are not able to follow the reactions at sufficiently short reaction times, or the equipment required is complicated and expensive, so it was not practical to run experiments to screen many important variables. A simple reactor system is devised to conveniently operate in the laboratory on a small scale at elevated temperatures and pressures so that many experiments can be run quickly and at relatively low cost.
