  • Catalyst and process for the production of hydrogen and/or methane
    Patent number: 5752995
    Abstract: A rare earth oxide stabilized, cobalt promoted nickel catalyst supported on refractory material, and a process employing said catalyst for the production of hydrogen-containing gases, such as synthesis gas, reducing gas or town's gas, or for the production of methane-enriched gases, such as pipe-line gas at low steam-to-carbon ratio not above 3.5 from various hydrocarbon feedstocks.
    Type: Grant
    Filed: June 30, 1994
    Date of Patent: May 19, 1998
    Inventor: Chia-chen Chu Kang
  • Process and catalysts for hydroconversion of coal or petroleum asphaltene to distillate liquids
    Patent number: 4917791
    Abstract: A two-stage catalytic hydroconversion process using a large-pore catalyst in the first stage reactor and a small-pore catalyst in the second stage reactor in the two-stage process for hydroconversion of coal or petroleum asphaltene feed materials to produce distillate liquid fuels. The large-pore catalyst is characterized by having pore diameters larger than 1000.ANG. occupying a major portion of the catalyst total pore volume of 0.2 to 1.0 cc/gm, and the small-pore catalyst is characterized by having pore diameters smaller than 1000.ANG. occupying a major portion of the catalyst total pore volume.
