| 20090048476 | Catalyst-Loaded Coal Compositions, Methods of Making and Use - The present invention relates to catalyst-loaded coal compositions having a moisture content of less than about 6 wt %, a process for the preparation of catalyst-loaded coal compositions, and an integrated process for the gasification of the catalyst-loaded coal compositions. The catalyst-loaded coal compositions can be prepared by a diffusive catalyst loading process that provides for a highly dispersed catalyst that is predominantly associated with the coal matrix, such as by ion-exchange. | 02-19-2009 |
| 20090217575 | Biomass Char Compositions for Catalytic Gasification - Particulate compositions are described comprising an intimate mixture of a biomass char producedfrom the combustion of a biomass, such as switchgrass or hybrid poplar, with at least a second carbonaceous material, such as petroleum coke or coal, and, optionally a gasification catalyst, for gasification in the presence of steam to yield a plurality of gases including methane and at least one or more of hydrogen, carbon monoxide, and other higher hydrocarbons are formed. Processes are also provided for the preparation of the particulate compositions and converting the particulate composition into a plurality of gaseous products. | 09-03-2009 |
| 20090217587 | Biomass Compositions for Catalytic Gasification - Particulate compositions are described comprising an intimate mixture of a biomass, such as switchgrass or hybrid poplar, a non-biomass carbonaceous material, such as petroleum coke or coal, and a gasification catalyst, where the gasification catalyst is loaded onto at least one of the biomass or non-biomass for gasification in the presence of steam to yield a plurality of gases including methane and at least one or more of hydrogen, carbon monoxide, and other higher hydrocarbons are formed. Processes are also provided for the preparation of the particulate compositions and converting the particulate composition into a plurality of gaseous products. | 09-03-2009 |
| 20090217588 | Co-Feed of Biomass as Source of Makeup Catalysts for Catalytic Coal Gasification - Continuous processes are provided for converting a carbonaceous feedstock comprising biomass containing alkali metal, non-biomass components, and at least one gasification catalyst including an alkali metal recovered from solid char, into a plurality of gaseous products including methane and at least one or more of hydrogen, carbon monoxide, and other higher hydrocarbons. | 09-03-2009 |
| 20100121125 | Char Methanation Catalyst and its Use in Gasification Processes - 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. | 05-13-2010 |
