A semi-continuous flow reactor technique for coal liquefaction studies

Abstract

A novel semicontinuous tubular reactor flow technique was used to study liquefaction of a typical Venezuelan coal. The technique allows a simple procedure to calculate coal liquefaction conversion. This was found to be increased by various catalysts only if the appropriate amount with the proper particle size was employed. Nickel—molybdate and cobalt—molybdate catalysts were found to be better catalysts than copper—chromite for desulfurizing the coal; however, the latter catalyst produced the largest liquefaction conversion.
