Publication number: 20180058382Abstract: A feedstock delivery system transfers a carbonaceous material, such as municipal solid waste, into a product gas generation system. The feedstock delivery system includes a splitter for splitting bulk carbonaceous material into a plurality of carbonaceous material streams. Each stream is processed using a weighing system for gauging the quantity of carbonaceous material, a densification system for forming plugs of carbonaceous material, a de-densification system for breaking up the plugs of carbonaceous material, and a gas and carbonaceous material mixing system for forming a carbonaceous material and gas mixture. A pressure of the mixing gas is reduced prior to mixing with the carbonaceous material, and the carbonaceous material to gas weight ratio is monitored. A transport assembly conveys the carbonaceous material and gas mixture to a first reactor where at least the carbonaceous material within the mixture is subject to thermochemical reactions to form the product gas.Type: ApplicationFiled: August 30, 2016Publication date: March 1, 2018Inventors: RAVI CHANDRAN, Daniel A. BURCIAGA, Daniel Michael LEO, Shawn Robert FREITAS, Dave G. NEWPORT, Justin Kevin MILLER, Kaitlin Emily HARRINGTON, Brian Christopher ATTWOOD, Emily Jane SCHULTHEIS, Kelly Ann KISHTON

Patent number: 9725663Abstract: A feedstock conversion system including an integrated two-stage fluid bed thermochemical reaction apparatus (50) has first and second reaction chambers (110, 120) side-by-side and physically separated from one another in one vessel (100) by a partition (130). One or more clusters of heat pipes (400) pass through the partition (130) between the first and second chambers (110, 120) for efficient indirect heat transfer between first and second fluid bed reaction stages (200, 300) and materials therein. The system includes devices for solids transfer between the two reaction chambers (110, 120) to enhance feedstock conversion.Type: GrantFiled: January 22, 2013Date of Patent: August 8, 2017Assignee: THEMOCHEM RECOVERY INTERNATIONAL, INC.Inventors: Ravi Chandran, Daniel Michael Leo, Shawn Robert Freitas
