20140235436 | HYDROTHERMAL PERFORMANCE OF CATALYST SUPPORTS - A high surface area catalyst with a mesoporous support structure and a thin conformal coating over the surface of the support structure. The high surface area catalyst support is adapted for carrying out a reaction in a reaction environment where the thin conformal coating protects the support structure within the reaction environment. In various embodiments, the support structure is a mesoporous silica catalytic support and the thin conformal coating comprises a layer of metal oxide resistant to the reaction environment which may be a hydrothermal environment. | 08-21-2014 |
20130161008 | PREPARATION AND USE OF NANO-CATALYSTS FOR IN-SITU REACTION WITH KEROGEN - Disclosed herein are methods for extracting a kerogen-based product from subsurface shale formations. The methods utilize in-situ reaction of kerogen involving liquid phase chemistry at ambient temperatures at pressures for the subsurface shale formation. These methods rely on chemically modifying the shale-bound kerogen to render it mobile using metal particulate catalysts. In the methods disclosed herein a fluid comprising metal is provided to the subsurface shale formation comprising kerogen in an inorganic matrix. A reducing agent is provided to the subsurface shale formation. The kerogen is converted by contacting the kerogen with a metal particulate catalyst formed from the metal; and a mobile kerogen-based product is formed. At least a portion of the mobile kerogen-based product is recovered. The kerogen-derived product can be upgraded to provide commercial products. | 06-27-2013 |
