Borgialli, R R

A batch-type, movable stirred microreactor for reacting a batch mixture of solid coal, liquid solvent and gaseous hydrogen at temperatures of 600/sup 0/-900/sup 0/F in about two to five minutes is described comprising: a sealed pressure vessel for holding reactants and having formed therein a first port for insertion of means for continuously monitoring temperature within the vessel, a second port means for feeding hydrogen into the pressure vessel to adjust the internal hydrogen pressure and a third port, a shaft extending into the pressure vessel through the third port, means for driving the shaft attached externally of the vessel, an impeller positioned within the vessel and attached to and driven by the shaft for stirring reactants in the vessel. The impeller comprises substantially vertical vanes attached to and surrounding the shaft, baffle means mounted above the impeller for breaking up a vortex in fluid motion around the shaft, and means for selectivity raising and lowering the microreactor into and out of a temperature controlled bath for controllably causing heating and cooling of a batch mixture contained therein within a desired time period.
