Abstract:
Disclosed is a method for removing water, nitrogen compounds, and unsaturated aliphatic compounds from a hydrocarbon feed stream by passing the hydrocarbon feed stream through a water removal zone, a nitrogen removal zone, and an unsaturated aliphatic compound removal zone. By on aspect, the method includes removing water from the hydrocarbon feed stream, contacting the feed stream with a nitrogen selective adsorbent, and contacting the feed stream with an unsaturated aliphatic compound removal material.
Abstract:
A process is presented for controlling the output of monoalkylated benzenes. The alkylbenzenes are linear alkylbenzenes and the process controls the 2-phenyl content of the product stream. The control of the process to generate a linear alkylbenzene with a 2-phenyl content within a desired range by recycling a portion of the effluent from the alkylation reactor to the inlet of the reactor.
Abstract:
A process for increasing the production of monoalkylbenzenes is presented. The process includes utilizing a transalkylation process to convert dialkylbenzenes to monoalkylbenzenes. The transalkylation process recycles a portion of the effluent stream from the transalkylation reactor back to the feed of the transalkylation reactor. The recycled dialkylbenzenes and a portion of the recycled benzene are converted to monoalkylbenzenes.
Abstract:
A process for acid catalyzed alkylation involving the use of surfactants which form bi-continuous micro-emulsions with the liquid acid and the hydrocarbon is described. The bicontinuous phase formed between the hydrocarbon and liquid acid phases at surfactant addition facilitates and improves the liquid acid catalyzed alkylation reactions including motor-fuel alkylation reaction.
Abstract:
A composition capable of removing chlorides from a gaseous stream and a process of using same. The compositions have sufficient chloride capacity, offer comparable creation of green oil, and have sufficient structural integrity to be utilized as sorbents in a chloride removal process. Generally, the compositions include a first zinc carbonate, a second zinc carbonate different than the first zinc carbonate and an alumina material. The composition has been cured at a temperature between about 149 to 399° C. The first zinc carbonate may comprise hydrozincite and the second zinc carbonate may comprise smithsonite.
Abstract:
A process for increasing the production of monoalkylbenzenes is presented. The process includes utilizing a transalkylation process to convert dialkylbenzenes to monoalkylbenzenes. The feed to the transalkylation process has alkylated toluenes and alkylated ethylbenzenes and other alkylated aromatics having small alkyl groups with less than 8 carbons removed to improve the efficiency of the transalkylation process. The recycled dialkylbenzenes and a portion of the recycled benzene are converted to monoalkylbenzenes.

Abstract:
A composition, process and apparatuses for removal of one or more contaminant anions from water are provided. In an embodiment, the process includes treating the water with a composition comprising a layered metal hydroxy salt, wherein the layered metal hydroxy salt is a compound comprising (a) a metal (b) a framework hydroxide, and (c) a replaceable anion.
