Abstract: A method of producing a acid/metal bifunctional catalyst may include: mixing an acid catalyst, a metal catalyst, and a fluid to produce a slurry, wherein the acid catalyst is present at 50 wt % or less relative to a total catalyst weight in the slurry; heating the slurry; producing a powder from the slurry; and calcining the powder to produce the acid/metal bifunctional catalyst. Such acid/metal bifunctional catalyst would be useful in the direct conversion of syngas to dimethyl ether as well as other reactions.

Abstract: Systems and methods are provided for conversion of gas phase reactants including CO and H2 to C2+ products using multiple catalysts in a single reactor while reducing or minimizing deactivation of the catalysts. Separate catalysts can be used that correspond to a first catalyst, such as a catalyst for synthesis of methanol from synthesis gas, and a second catalyst, such as a catalyst for conversion of methanol to a desired C2+ product. The separate catalysts can be loaded into the reactor in distinct layers that are separated by spacer layers. The spacer layers can correspond to relatively inert particles, such as silica particles. Optionally, the spacer layer can include an adsorbent, such as boron supported on alumina or boron carbide particles. The adsorbent can be suitable for selective adsorption of the one or more reaction products (such as one or more reaction by-products), to allow for further reduction or minimization of the deactivation of the conversion catalysts.

Abstract: A method for recovering oil from a subterranean, hydrocarbon-bearing formation includes at least one injection well and injecting a carrier fluid including a diverting agent into a high permeability pathway within the formation. An activating fluid is injected into the high permeability pathway within the formation, resulting in the precipitation or swelling of the diverting agent. The permeability of the high permeability pathway is decreased within the formation containing the diverting agent to a permeability less than the permeability of the adjacent areas of the formation. A mineralization fluid may be injected that is oversaturated or becomes oversaturated upon interacting with the acid gas that causes mineral precipitation to seal off high-permeability pathways.
