  • Char methanation catalyst and its use in gasification processes
    Patent number: 8502007
    Abstract: The invention provides processes for generating a methane-enriched gas from a gas mixture comprising carbon monoxide and hydrogen such as gas streams generated by gasification of an alkali metal catalyst-loaded carbonaceous feedstock, and a char methanation catalyst useful in such processes.
    Type: Grant
    Filed: September 18, 2009
    Date of Patent: August 6, 2013
    Assignee: Greatpoint Energy, Inc.
    Inventors: Edwin J. Hippo, Vincent G. Reiling, Earl T. Robinson, Pattabhi K. Raman, Jeffery Smith, Charles Mims, Nicholas Charles Nahas
  • Processes for gasification of a carbonaceous feedstock
    Patent number: 8328890
    Abstract: The present invention relates to processes for preparing gaseous products, and in particular, methane via the catalytic gasification of carbonaceous feedstocks in the presence of steam and an oxygen-rich gas stream. The processes comprise using at least one catalytic methanator to convert carbon monoxide and hydrogen in the gaseous products to methane and do not recycle carbon monoxide or hydrogen to the catalytic gasifier.
