    摘要： A hockey puck has a generally cylindrical body having an upper face, a lower face and a circumferential wall with a generally spherical puck element secured centrally within the body and being rotatable with respect to the puck body. In a preferred embodiment, the generally spherical puck element has a weight greater than that of the body and a diameter greater than the distance between the upper face and lower face. The generally spherical puck element is secured within an inner member which in turn has a ring disposed radially outwardly thereof and secured to the inner member. The puck is structurally designed to have the generally spherical puck element have translational and rotational kinetic energy while the body will have translational or translational and rotational kinetic energy. This results an enhanced ability to maintain the puck on the desired path despite roughness of the surface on which it is moving or certain types of impact with other objects.

    摘要： Middle distillate petroleum streams are hydrotreated to produce a low sulfur and low aromatic product in a process employing three reaction zones in series. Hydrogen flows between the reaction zones countercurrent to the hydrocarbons. Hydrogen sulfide is removed from effluent of the first two reaction zones by hydrogen stripping. The second and third reaction zones employ a sulfur-sensitive noble metal hydrogenation catalyst. Operating pressure increases and temperature decreases from the first to third reaction zones.

    摘要： Although high naphthenic acid hydrocarbon feedstocks normally need to be washed with caustic prior to being sweetened in a fixed bed mercaptan-to-disulfide oxidation process to avoid bed plugging, the prewash can be eliminated if aqueous ammonia is used concurrent with and as a part of the sweetening process. Aqueous ammonia injected into a sour hydrocarbon stream prior to the sweetening zone not only eliminates bed plugging, but affords an aqueous phase from which naphthenic acids may be recovered easily and economically. The ammonia also can be recovered for reuse, affording a process with considerably enhanced economic return.

    摘要： A process for obtaining glucose from thinned starch by partially hydrolyzing the latter to give from 50% to 92% glucose followed by separation of the hydrolysis product to afford a glucose-enriched product with recycling of the glucose-depleted stream affords benefits unattainable by conventional commercial processes. Substantial reductions in process time and reversion products and a substantial increase in productivity are among some of the benefits.

    摘要： A catalyst regeneration apparatus for the oxidation of coke from a spent catalyst, said coke being converted to CO, and for the conversion of the CO to CO.sub.2. Hot regenerated catalyst is recycled from a dense bed in the regeneration zone to mix with incoming spent catalyst in a mixer zone. The mixer zone operates in dense phase and is supplied with a relatively small amount of a fluidizing medium, preferably air. After the mixing of spent and fresh catalyst is substantially completed, a relatively large amount of a regenerating gas, preferably air, is admixed with the catalyst mixture, and some coke oxidation occurs. The balance of coke oxidation takes place in a downstream-situated regeneration zone of substantially conventional design. There is a transfer section connecting the mixer zone to the regeneration zone through which the relatively large amount of the regenerating gas is admitted. The transfer section is preferably a frustoconical surface, the horizontal cross section of smallest perimeter of which adjoins the outlet of said mixer zone, and regenerating gas addition is made at the base of the transfer section in order to provide a venturi effect which ensures good air-catalyst mixing.
