Abstract: A process for treating a hydrocarbon liquid composition to improve its storage and/or transportation stability, comprises contacting the hydrocarbon liquid composition with a polar trap, wherein the conductivity of the hydrocarbon liquid composition is not reduced by said contacting with a polar trap. The polar trap may be a clay treater containing attapulgus clay. The process may include sequentially passing the hydrocarbon liquid composition through a dehydrator and a clay treater at a flow rate of between about 100 and about 1000 m3 per hour. Advantageously, the hydrocarbon liquid composition is refined and in particular, may be a Merox™-treated jet fuel.

Abstract: Abstract Described is a desorption process and a process for producing a catalytically deactivated formed zeolitic adsorbent, whereby both processes are suitable to improve the lifetime of a formed zeolithic adsorbant in the removal of sulfur compounds from sulfur contaminated gas and liquid feed streams. The adsorbent is in particular a synthetic 13X or LSX faujasite with a silica to alumina ratio from 1.9:1.0 to about 3.0:1.0. The cations of the faujasite include alkali and alkaline earth metals. The formed zeolite mixture is preferably catalytically deactivated due to a phosphate treatment. The desorption is carried out thermally, wherein the heat treatment is done at different temperature stages to avoid decomposition of the organic sulfur compounds.

Abstract: 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.

Abstract: Disclosed is a liquid phase adsorption process for removing and concentrating heteroatom compounds in hydrocarbons (HCH), comprising the steps of adsorption, copurging and regeneration. In the adsorption step, a liquid hydrocarbon stream is fed to an adsorber, which adsorbs HCH and returns adsorption effluent. In the copurging step, HCH, which are extracted from the previous regeneration, are applied to the adsorber, displacing the copurging effluent. In the regeneration step, a polar solvent is flowed through the adsorber, purging HCH. Most of the HCH are then set aside for use in the next copuring step, while a small amount of the HCH are taken out from the process as HCH product. The present invention is economically advantageous in effectively removing HCH from hydrocarbon streams and increasing the concentration of HCH within an HCH product.

Abstract: CuY and AgY zeolites as selective sorbents for desulfurization of liquid fuels. Thiophene and benzene were used as the model system, and vapor phase isotherms were measured. Compared with NaY, CuY and AgY adsorbed significantly larger amounts of both thiophene and benzene at low pressures. It is hypothesized that this is due to null-complexation with Cunull and Agnull. On a per-cation basis, more thiophene was adsorbed by Cunull than by Agnull, eg. 0.92 molecule/Cunull versus 0.42 molecule/Agnull at 2null10null5 atm and 120null C. Molecular orbital calculations confirmed the relative strengths of null-complexation: thiophene>benzene and Cunull>Agnull. The experimental heats of adsorption for null-complexation are in qualitative agreement with theoretical predictions. The invention further comprises a process and sorbents for removal of aromatics from hydrocarbons.
