Patent number: 10329490Abstract: The present disclosure provides a method of producing a solid carbon material. The method comprises providing a carbon-containing material formed through the heat treatment of carbonaceous feedstock. The carbon-containing material is capable of undergoing polymerisation. The method further comprises mixing the carbon-containing material with a polymerisation agent to form a material mixture. In addition, the method comprises heating the material mixture to a temperature at which polymerisation of the material mixture occurs so as to produce the solid carbon material. The method also comprises adding a further material into the material mixture before polymerisation.Type: GrantFiled: April 13, 2016Date of Patent: June 25, 2019Assignee: Curtin UniversityInventors: Chun-Zhu Li, Xun Hu

Patent number: 10144887Abstract: A method of gasifying carbonaceous material is described. The method comprises a first step of pyrolyzing and partially gasifying the carbonaceous material to produce volatiles and char. The volatiles and the char are then separated and, subsequently, the char is gasified and the volatiles are reformed. The raw product gas is then finally cleaned with char or char-supported catalysts or other catalysts.Type: GrantFiled: March 18, 2015Date of Patent: December 4, 2018Assignee: CURTIN UNIVERSITY OF TECHNOLOGYInventors: Chun-Zhu Li, Hongwei Wu, Mohammad Asadullah, Xiaoshan Wang

Patent number: 9994774Abstract: A pyrolysis plant 20 comprises a grinding pyrolyzer 22, being a machine or apparatus in which both particle size reduction and pyrolysis occur simultaneously. Plant 20 also comprises a bin (hopper) 30 for holding wet particulate biomass feedstock. Chute 32 leads from the bin 30 to a biomass dryer 34 which reduces moisture content of the feedstock as low as possible, e.g., to below about 10. Dried feedstock is conveyed from dryer 34 via line 36 to a dried biomass feedstock hopper 38. Dried feedstock is fed from hopper 38 into a chute 40 which leads to an inlet trunnion 42 of grinding pyrolyzer 22. A discharge trunnion 44 of grinding pyrolyzer 22 leads to a char holder 60 for collecting char particles and a condensation train 62 for condensing vapor generated by the pyrolysis to produce oil.Type: GrantFiled: June 21, 2011Date of Patent: June 12, 2018Assignee: Curtin University of TechnologyInventors: Chun-Zhu Li, Xiaoshan Wang, Hongwei Wu

Patent number: 9957444Abstract: An apparatus for pyrolyzing a carbonaceous material and producing char and volatiles includes a vessel having an inlet for the carbonaceous material, an outlet for the char and the volatiles, and a first pathway therebetween. The vessel has wall portions with interior surfaces that define the first pathway. Further, the vessel has a heat exchange medium inlet, outlet and a second pathway therebetween. The first and second pathways are in heat exchange proximity to each other and the second pathway is defined by interior surfaces of the, or other, wall interior portions of the vessel. At least some of the interior wall portions of the vessel project into an interior space of the vessel such that at least one of the first and second pathways is non-linear.Type: GrantFiled: December 16, 2014Date of Patent: May 1, 2018Assignee: RENERGI PTY LTDInventors: Chun-Zhu Li, Richard Gunawan, Li Dong

Patent number: 9828247Abstract: The present disclosure provides a process for cleaning raw product gas. The process includes contacting the raw product gas with a flow of catalyst to reform organic contaminants and inorganic contaminants in the raw product gas and to remove particulates. Further, the process includes cooling the resulting product gas via heat exchange with a heat exchange medium in the presence of char or a solid adsorbent medium to condense remaining organic contaminants and inorganic contaminants on the char or solid adsorbent medium and to filter out fine particulates.Type: GrantFiled: December 16, 2014Date of Patent: November 28, 2017Assignee: RENERGI PTY LTDInventors: Chun-Zhu Li, Richard Gunawan, Li Dong
