DEVELOPMENT OF A PULSE-INJECTION SHORT CONTACT TIME COAL-LIQUEFACTION FLOW REACTOR

A well-mixed reactor was developed to study the initial reaction pathways and mechanisms of direct coal liquefaction. This pulse-injection flow vessel exploits the reactor residence time distribution to obtain an isothermal series of samples of well-defined holding times from 10 to 900 s. The reactor design also allowed for quick and efficient procurement of optimally spaced and sized samples. The operation of this reactor is illustrated using both model compound and coal liquefaction experiments.
