    Abstract: A riser includes a housing in communication with a entry conduit and an exit conduit. The housing is defined by a holdup chamber having a volume of between about 1133 liters and about 45307 liters. The riser is designed to receive a hydrocarbon feed and a catalyst. An apparatus for fluid catalytic cracking includes a riser in fluid communication with a reactor vessel. A hydrocarbon feed stream and a catalyst travel through a first section of the riser at a first velocity of between about 1.5 msec to about 10 msec and through a second section of the riser at a second velocity of more than about 15 msec. A process for fluid catalytic cracking uses a riser with a holdup chamber. A hydrocarbon feed and a catalyst decrease in velocity in the holdup chamber to between 1.5 msec and 10 msec.

    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: A multiple anvil press can be configured for gem-quality growth. The press can include a plurality of opposing anvils, where the anvils are configured for simultaneous movement within a tolerance of less than about 0.5 mm as measured at each anvil surface, and each anvil can be aligned to a common center of all the anvils where the alignment is tuned to a tolerance of less than about 0.1 mm during use. The press can also include a reaction volume formed by the enclosure of all anvils, where the reaction volume has a size configured to facilitate single crystal growth per cycle time.

    Abstract: Methods of synthesizing superabrasive particles such as diamonds and cubic boron nitride are disclosed and described. One procedure includes providing a superabrasive precursor including a source material in a metal matrix. The carbon source can contain a majority of carbon atoms oriented in a rhombohedral polytype configuration. A shock wave can be passed through the carbon source that is sufficient to convert the diamond to graphite. The superabrasive precursor can be formed by dissolving hexagonal carbon in a suitable molten metal or by mixing particulate components. Similarly, hexagonal boron nitride can be used in a metal matrix which is subjected to a shock wave having sufficient energy to form cubic boron nitride. The superabrasive particles produced using these methods can be provided at relatively high yields with reduced costs.
