ABSTRACT OF THE DISCLOSURE A high pressure reaction vesselhas a container portion and a removable head portion which houses a flow channel or channels, valve members and valve operators, and which seals and covers the container portion. Each channel terminates at a tapered valve seat angled at at least 36° with respect to the horizontal and each of the valves is provided with a mating tapered surface which is wedged more tightly within the valve seat as pressure within the vessel increases. A port and a chute are provided for introducing a particulate solid feed through at least one of the channels into the interior of the vessel. In one embodiment a dip tube depends from a second valve seat (in communication with a second channel) and extends to a point adjacent the bottom of the container portion. In the preferred embodiments the head portion is surrounded by a removable flange having a central tapered opening and is in the form of a plug member in which the channels are formed and which carries the valve seats, valves and valve operators. The circumference of the plug member is tapered to mate with the tapered surface of the removable flange in such a way that increasing pressure within the vessel enhances the seal between the plus member and the central opening of the removable flange. In one embodiment the body portion of the reaction vessel is provided with a liner of a halogenated hydrocarbon resin which extends upward to a seal between the tapered surfaces of the plug member and the central opening of the removable flange and is pinched more tightly therebetween as pressure within the vessel increases. In another embodiment the liner is tubular and similar removable flanges, with mating plug members, are provided at top and bottom of the container with a wedged valve and valve seat providing for solids discharge through the bottom plug member.
