摘要： A three-phase liquid polishing and cleaning composition of the invention is suitable for polishing and cleaning a painted exterior surface, and includes an organic phase, an aqueous phase, and a particulate phase. The organic phase comprises a petroleum-based liquid and the aqueous phase comprises water. The particulate phase comprises at least one particulate polishing grade abrasive having a mean particle size of not more than about 2.5 microns, which is selected from the group consisting of an abrasive that is harder than the painted surface to be polished and cleaned, and an abrasive that is softer than the painted surface to be polished and cleaned. The composition comprises at least one surfactant (e.g., an anionic surfactant, an emulsifying agent, and a foaming agent) to emulsify the organic and aqueous phases upon mixing (e.g., shaking) the composition, and to suspend the particulate phase in the emulsified organic and aqueous phases.

摘要： Processing schemes and arrangements are provided for obtaining propylene and propane via the catalytic cracking of a heavy hydrocarbon feedstock and converting the propylene into cumene without separating the propane from the propane/propylene feed stream. The disclosed processing schemes and arrangements advantageously eliminate any separation of propylene from propane produced by a FCC process prior to using the combined propane/propane stream as a feed for a cumene alkylation process. A bottoms stream from the cumene column of the cumene alkylation process can be used and an absorption solvent in the FCC process thereby eliminating the need for a transalkylation reactor and a DIPB/TIPB column.

摘要： This ethylbenzene process involves contacting, in an alkylation zone, a first benzene recycle stream and an ethylene feed stream with an alkylation catalyst to form ethylbenzene. In a transalkylation zone, a polyethylbenzene recycle stream and a second benzene recycle stream are contacted with a transalkylation catalyst to form additional ethylbenzene.

An ethylbenzene stream is removed from an intermediate point of the dividing wall fractionation column; a first benzene recycle stream is removed from a first end and a flux oil stream is removed from a second end. A second benzene recycle stream is removed from an intermediate point located between the first end and the ethylbenzene stream. A polyethylbenzene stream is removed from an intermediate point of located between the second end and the ethylbenzene stream.

摘要： In an alkylation zone, a benzene recycle stream and a propylene feed stream are contacted with an alkylation catalyst to convert the propylene and benzene into cumene. In a transalkylation zone, a polyisopropylbenzene stream and a benzene recycle stream are contacted with a transalkylation catalyst to convert the polyisopropylbenzene and benzene into cumene. The alkylation and transalkylation zone effluents are passed into a dividing wall fractionation column.A cumene product stream is removed from an intermediate point of the dividing wall fractionation column. A benzene recycle stream is removed from a first end, and another benzene recycle stream is removed from an intermediate point of the dividing wall fractionation column. A polyisopropylbenzene stream is removed from a second end of the dividing wall fractionation column. The polyisopropylbenzene stream is passed to a polyisopropylbenzene fractionation column to separate the polyisopropylbenzene from a heavy ends stream.

摘要： A process for the removal of sulfur-oxidated compounds from a hydrocarbonaceous stream containing sulfur-oxidated compounds wherein the hydrocarbonaceous stream containing sulfur-oxidated compounds is contacted with an adsorbent which selectively adsorbs sulfur-oxidated compounds from the hydrocarbonaceous stream to produce an adsorbent having adsorbed sulfur-oxidated compounds. The loaded adsorbent containing sulfur-oxidated compounds is contacted with a desorbent to produce a desorbent containing sulfur-oxidated compounds and an adsorbent having a reduced content of sulfur-oxidated compounds. The regenerated adsorbent is then used to remove additional sulfur-oxidated compounds.
