The design and operation of a time-sampled reactor system are described. It can be used to charge reactants rapidly into a preheated stirred-tank autoclave and to sample its contents throughout the course of reaction. Results are presented that show representative sampling of the liquid phase is achieved. Gas solubility results are presented showing that gas yield data are also reliable. The hydroliquefaction of Morwell brown coal employing this reactor facility in both the hot-charge and slow heat-modes has been investigated. An insight into the mechanisms in the initial reaction period is provided.
