    Abstract: A cutting element include a substrate and a diamond compact including at least two polycrystalline diamond portions separated by at least one metal carbide foil portion. The cutting element is made by placing diamond powder in a reaction container, placing a thin metal layer in the reaction container above or around the diamond powder and binder, placing additional diamond powder in the reaction container above or around the thin metal layer, and placing a pre-sintered substrate containing binder into the reaction container above all diamond powder and thin metal layer components. The assembled reaction container is put into a reactor and is subjected to a high-temperature high-pressure sintering process. The binder in the pre-sintered substrate sweeps through to sinter the first diamond portion, and then reacts with the thin metal layer to form a metal carbide, and then the binder continues to sweep through to sinter the second diamond portion.

    Abstract: Embodiments relate to polycrystalline diamond compacts (“PDCs”) that are less susceptible to liquid metal embrittlement damage due to the use of at least one transition layer between a polycrystalline diamond (“PCD”) layer and a substrate. In an embodiment, a PDC includes a PCD layer, a cemented carbide substrate, and at least one transition layer bonded to the substrate and the PCD layer. The at least one transition layer is formulated with a coefficient of thermal expansion (“CTE”) that is less than a CTE of the substrate and greater than a CTE of the PCD layer. At least a portion of the PCD layer includes diamond grains defining interstitial regions and a metal-solvent catalyst occupying at least a portion of the interstitial regions. The diamond grains and the catalyst collectively exhibit a coercivity of about 115 Oersteds or more and a specific magnetic saturation of about 15 Gauss·cm3/grams or less.

    Abstract: A method of producing a composite diamond compact comprising a polycrystalline diamond (PCD) compact bonded to a cemented carbide substrate is provided. The method includes the steps of: providing a PCD table, preferably a PCD table with diamond-to-diamond bonding and a porous microstructure in which the pores are empty of second phase material bringing together the PCD table and a cemented carbide substrate in the presence of a bonding agent to form an unbonded assembly; subjecting the unbonded assembly to an initial compaction at a pressure of at least 4.5 GPa and a temperature below the melting point of the bonding agent for a period of at least 150 seconds; and thereafter subjecting the unbonded assembly to a temperature above the melting point of the bonding agent and a pressure of at least 4.5 GPa for a time sufficient for the bonding agent to become molten and bond the PCD table to the substrate to form a composite diamond compact.

    Abstract: Cryptomelane-type manganese oxide octahedral molecular sieves (OMS-2) supported Fe and Co catalysts are utilized in a method for producing hydrocarbons by a Fischer-Tropsch mechanism. The hydrocarbon producing method includes providing a catalyst of a manganese oxide-based octahedral molecular sieve nanofibers with an active catalyst component of at least one of iron, cobalt, nickel, copper, manganese, vanadium, zinc, and mixtures thereof, and further containing an alkali metal. The formation of iron carbides and cobalt carbides by exposing the catalyst to conditions sufficient to form those carbides is also taught. After the catalyst has been appropriately treated, a carbon source and a hydrogen source are provided and contacted with the catalyst to thereby form a hydrocarbon containing product. The catalyst have high catalytic activity and selectivity (75%) for C2+ hydrocarbons in both CO hydrogenation and CO2 hydrogenation. Highly selective syntheses of high value jet fuel, C2-C6 alkenes, C2-C6 carboxylic acids; α-hydroxylic acids and their derivatives have been realized by tuning the oxidation ability of OMS-2 supports and by doping with Cu2+ ions.
