Title: Method of preheating carbonaceous materials prior to their destructive hydrogenation
IPC: C10G1/06
Filed: 1928-12-08
Abstract: 330,498. Tate, W. R., Stephenson, K. P., and Imperial Chemical Industries, Ltd.. Dec. 8, 1928. Hydrogenation, destructive. - Carbonaceous materials are pre-heated, prior to destructive hydrogenation, in two or more stages at successively higher pressures. The first stage or stages may be performed in absence of hydrogen, without substantial decomposition of the material. The succeeding stage or stages may be carried out in presence of hydrogen, the, last stage being at the pressure of the reaction. In an example, a paste of coal and oil with hydrated ferric oxide catalyst is made in a steam-heated mixer, from which it passes through a steamheated stirrer and pump to a low-pressure heater of tubular type in which the temperature, is raised to 300‹ C. The material in a freely-flowing condition is then forced into a second heater supplied with hydrogen under the reaction pressure of 200 atmospheres, and is heated to the reaction temperature. In another example, materials are heated at atmospheric pressure to 275‹ C., at 20- 30 atmospheres to 350‹ C., and finally at 250 atmospheres to 420-450‹ C. The total time occupied by the pre-heating is 10 minutes, while the duration of the reaction is 1 to 2 hours. The material flows at 1.5 to 3 ft. per sec. through the heaters. Agitation steps may be introduced between the stages. The process may be combined with that of Specification 322,645. The final stage of pre-heating may be brought about in the reaction vessel itself by means of superheated hydrogen.
