  • Method of gasifying carbonaceous material and a gasification system
    Patent number: 10144887
    Abstract: 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: Grant
    Filed: March 18, 2015
    Date of Patent: December 4, 2018
    Assignee: CURTIN UNIVERSITY OF TECHNOLOGY
    Inventors: Chun-Zhu Li, Hongwei Wu, Mohammad Asadullah, Xiaoshan Wang

  • Method for gasifying biomass and catalyst used for said method
    Publication number: 20060032139
    Abstract: Disclosed is a method of gasifying a biomass, comprising heating a fluidized bed reactor loaded with a catalyst represented by Rh/CeO2/M, where M represents SiO2, Al2O3 or ZrO2, to temperatures lower than 800° C. introducing biomass particles into the fluidized bed reactor from an upper portion thereof, introducing air and steam into the fluidized bed reactor from a lower portion thereof, and allowing the biomass particles to react at the surface of the Rh/CeO2/M catalyst so as to manufacture hydrogen and a syngas.
