Patent number: 4169128Abstract: Disclosure is made of an apparatus for reacting carbonaceous material with heated hydrogen to form hydrocarbon gases and liquids suitable for conversion to fuels wherein the reaction involves injection of carbonaceous material such as pulverized coal entrained in a minimum amount of gas and mixing the entrained coal at near ambient temperature with a separate source of heated hydrogen. The hydrogen is heated in a coil having an increasing inside diameter. The heated hydrogen and entrained coal are injected through a rocket engine type injector device. The coal particles are reacted with hydrogen in a reaction chamber downstream of the injector. The products of reaction are rapidly quenched as they exit the reaction chamber and are subsequently collected.Type: GrantFiled: February 24, 1977Date of Patent: September 25, 1979Assignee: Rockwell International CorporationInventors: Jerry E.

Patent number: 3949941Abstract: An apparatus for converting thermoplastic waste material into a commercial-grade granular material wherein the waste material is introduced into a chamber containing a rotating cutter which shreds and frictionally heats the thermoplastic material which is thereafter cooled by cooling water added to the material while the cutting operation continues. The cooling water or vapor is then withdrawn or exhausted from the container under negative pressure leaving the granular material dry. Also, solvents are removed from the material. The cutter blade may include baffle bars which provide frictional heating surfaces for heating the thermoplastic waste material.Type: GrantFiled: April 9, 1975Date of Patent: April 13, 1976Inventors: Bob P.
