ABSTRACT:
In plant for hydrogenating coal to form hydrocarbons, wherein coal in powder or piece form is fed from a hopper into a preparation chamber, is compressed, conveyed and heated by a rotor comprising a rotating friction element and passed, through a feed aperture, into a hydrogenation chamber wherein hydrogen is injected into it by nozzles, monitoring and controlling means are provided whereby upon the pressure in the hydrogenation chamber rising above that in the end of the preparation chamber adjacent the hydrogenation chamber, as measured by sensors and gauges, the feed aperture is closed and the rotor is stopped. Preferably the feed aperture is closed by providing a conical portion on the rotor and a conical seat on the cylinder forming the chamber, the rotor normally being held in a position to keep the feed aperture open by an hydraulic cylinder but upon the pressure sensors sensing over pressure in the chamber, the cylinder is vented by control means to close the feed aperture. The rotor is also stopped by the control means.
