Abstract

262,278. Bube, K. Dec. 22, 1925. Materials and compositions for making gas, coke, and other products. - Active carbon in powdered form is produced at low temperatures by heating oils which are normally incapable of being cracked economically, with or without the addition of carbonaceous substances, in pressureresistant vessels to a temperature of from 350‹ to 500‹ C. in such a manner that part of the oil remains liquid during the reaction, and simultaneously discharging the liquid gaseous and solid reaction products through a common outlet. The pulverulent active carbon obtained may then be submitted to a purifying treatment by means of hot water. In an example, producer gas tar obtained from lignite is pumped through pipes heated to between 350‹ and 500‹ C. at such a speed that carbon does not deposit on the walls of the vessel, volatilization within the reaction tube being minimized by means of throttling-valves. In another example, a mixture of powdered lignite with heavy lignite oil is pumped through a tube heated to about 400‹ to 500‹ C. and the exit of the tube is throttled in such a way that carbon, oil, ashes, and gases leave simultaneously. Crude mineral oils rich in asphalt may be employed in admixture with coal, sawdust, or other carbonaceous substances.
