Abstract: A method of making a heterogenously supported catalyst useful in dimerization, oligomerization or polymerization is provided in which a catalyst precursor containing a metal and an aromatic group are alkylated onto an oligomeric support having at least one terminal unsaturated group by Friedel Crafts alkylation.

Abstract: An upper part (1) of an assembled piston is disclosed, comprising a radially directed inner contact surface (2) arranged on the underside of an annular rib (15) and a radially directed outer contact surface (3) arranged on the underside of an annular wall (25), the outer (3) and the inner contact surface (2) each having a grooved profile in the form of concentric grooves with an average depth between Rz 10 and Rz 30. The wear on the contacting surfaces of the upper piece and the lower piece of the assembled piston is thus reduced.

Abstract: Methods and apparatus relate to treatment of fluids to remove mercury contaminants in the fluid. Contact of the fluid with active outer surfaces of particles magnetically separable from the fluid loads the particles with the mercury contaminants. Magnetic separation then removes from the fluid the particles loaded with the mercury contaminants such that a treated product remains.

Abstract: The present method describes the absorbing and desorbing of a gaseous reactant on a solid reactant. The solid reactant is an ammonia salt selected from the group consisting of alkali ammonium salts, alkali ammonium earth salts or a combination thereof.

Abstract: Methods and apparatus relate to treating fluid to at least reduce selenium content within the fluid, which may be an aqueous liquid and form a feed stream. The treating removes selenium that may be present in compounds, such as selenocyanate, from the feed stream based on adsorption from contact of the fluid with a sorbent. Flowing a gaseous hydrogen sulfide and sulfur dioxide containing stream over a support, such as activated carbon, may provide the sorbent impregnated with sulfur and utilized in the treating of the fluid.

Abstract: A starter device for an internal combustion engine (10) has an actuating device and an entrainer (24) can be coupled to the crankshaft (13) of the engine (10). The entrainer (24) and the actuating device are rotatably journalled about a rotational axis (14). The entrainer (24) and the actuating device are connected to each other via a damping spring (23). The damping spring (23) is connected with a first end (26) to the actuating device and with a second end (27) to the entrainer (24). The entrainer (24) and the actuating device have respective supports (21, 42). The damping spring (23) is mounted on the outer periphery of the two supports (21, 42). In the direction of the rotational axis (14), a disc (22) is mounted between the two supports (21, 42) in order to avoid the situation that the damping spring (23) can force itself into a gap between the two supports (21, 42) which gap can arise during operation.

Abstract: Methods of oligomerizing hydrocarbons are disclosed. These methods include contacting olefins with an oligomerization catalyst in an oligomerization zone under oligomerization reaction conditions.

Abstract: A method for regenerating desulfurization sorbents that minimizes the in situ formation of one or more silicates. It has been discovered that regenerating sulfur-laden sorbent particles in a carbon oxide-rich environment unexpectedly reduces the in situ silicate formation rate, as compared to similar sorbents regenerated using conventional methods.

Abstract: A catalyst comprising at least one metal selected from the group consisting of Group 8 metals, Group 9 metals, Group 10 metals and combinations thereof, an organic compound, and a solid acid and a method of making said catalyst is disclosed. The catalyst can be used in a hydrocarbon conversion process.

Abstract: A brake actuating device has an actuator functionally connected between a piston and a brake pedal lever. The actuator is capable of varying the path length of a force-conducting connection between the brake pedal lever and the piston of the brake cylinder via a displaceable element. A spring element acts on the brake pedal lever. The spring force varies during the variation of the path length such that a sum of the spring force and a force acting on the brake pedal lever from the brake cylinder remains essentially unchanged. The spring element is fastened with one end to the displaceable element and with the other end to the brake pedal lever with the interposition of a tensioning mechanism, which is guided by a cam track provided on the brake pedal lever.

Abstract: Methods and apparatus relate to treatment of fluids to remove mercury contaminants in the fluid. Contact of the fluid with active outer surfaces of particles magnetically separable from the fluid loads the particles with the mercury contaminants. Magnetic separation then removes from the fluid the particles loaded with the mercury contaminants such that a treated product remains.

Abstract: A series of new bis(imino)pyridine vanadium(III) complexes was synthesized according to formula: They were tested for the homogeneous catalytic dimerization of propylene after activation with MAO and showed excellent selectivity for dimerization. The catalysts can be used with or without PPh3 as an additive to produce ?80% dimerized alkenes.

Abstract: A process is disclosed for removing heavy metals from a hydrocarbon gas stream by contacting the hydrocarbon gas stream, which contains a heavy metal and less than 10 ppm oxidizing compounds, with a composition containing a molecular sieve and sulfur resulting in a treated stream containing less heavy metal than the hydrocarbon gas stream; wherein the molecular sieve contains alumina, silica, and iron, and optionally copper and zinc. Optionally, the hydrocarbon gas stream can also contain a sulfur compound.

Abstract: A process for disproportionating isopentane into isomers of hexane and butane that utilizes a fixed bed reactor employing a catalyst composition comprising aluminum halide. The process additionally includes a product separation zone which can be configured to recover and return at least a portion of the isopentane product stream to the inlet of the disproportionation reactor.
