摘要:
Methods of oligomerizing hydrocarbons are disclosed. These methods include contacting olefins with an oligomerization catalyst in an oligomerization zone under oligomerization reaction conditions.
摘要:
A composition comprising a promoter and a metal oxide selected from the group consisting of a gallium oxide, an indium oxide, and combinations of any two or more thereof, wherein at least a portion of the promoter is present as a reduced valence promoter and methods of preparing such composition are disclosed. The thus-obtained composition is employed in a desulfurization zone to remove sulfur from a hydrocarbon stream.
摘要:
A drainage deck assembly for a rotary vacuum drum filter having filtrate compartments on the outer surface of the drum comprised of premolded interlocked grid sections formed with integral baffle walls for directing the flow of filtrate outwardly of the filtrate compartments and which grid sections are provided with rows of filtrate receptacle trays in the surface thereof having bottom walls formed with filtrate discharge slots located at a position to prevent return flow of filtrate to the receptacle.
摘要:
Attrition resistant, sorbent compositions for the removal of elemental sulfur and sulfur compounds, such as hydrogen sulfide and organic sulfides, from cracked-gasoline and diesel fuels are prepared by the impregnation of a sorbent support comprising zinc oxide, expanded perlite, and alumina with a promoter such as nickel, nickel oxide or a precursor of nickel oxide followed by reduction of the valence of the promoter metal in the resulting promoter metal sorbent support composition. Also disclosed is a composition comprising desulfurized, cracked-gasoline wherein the desulfurized cracked-gasoline comprises less than about 1 ppmw thiol compounds and less than about 1 ppmw tetrahydrothiophene compounds.
摘要:
A method for displaying dosage indicia includes engaging a dispenser housing with a container in an engaged position, moving the container relative to the dispenser housing along a longitudinal axis while the container and the dispenser housing are in the engaged position, moving a valve between a closed position and an open position in response to moving the container relative to the dispenser housing and thereby dispensing metered dosages of substance when the valve is moved to the open position, moving the container relative to the dispenser housing to a disengaged position, moving an indicating portion with the container as the container is moved relative to the dispenser housing between the engaged and disengaged positions, and moving the indicator member relative to the container along the longitudinal axis while the container is in the engaged position.

摘要:
A deactivated sorbent composition is reactivated by contacting the deactivated sorbent with a reducing stream under activation conditions sufficient to reduce the amount of sulfates associated with the sorbent composition.
摘要:
Continuous glass fiber reinforced composites are made by pultruding the fibers with mixtures of certain silanes and thermoplastic resin in which the silanes have adsorbed onto the thermoplastic resin.
摘要:
An indicating device includes an indicating portion and an actuator portion. At least a part of the indicating portion is moveable with a container between engaged and disengaged positions relative to a dispenser housing. The indicating portion includes at least one indicator member. The container is moveable relative to the at least one indicator member along the longitudinal axis when the container is in the engaged position.
