Abstract: The present invention relates to the removal of mercury and other heavy metals from a hydrocarbon feedstream. The process involves contacting the hydrocarbon feedstream with a feedstream-soluble sulfur compound and then contacting the hydrocarbon feedstream and solubilized sulfur compound with an adsorbent.

Abstract: A process for the preparation of a catalyst useful for conducting carbon monoxide hydrogenation reactions, especially Fischer-Tropsch reactions. The steps of the process begin with the activation, or reactivation, of a deactivated catalyst, or with the preparation and activation of a fresh catalyst. In accordance with the latter, the steps of the process comprise, first contacting, in one or more steps, a powder or preformed, particulate refractory inorganic support with a liquid, or solution in which there is dispersed or dissolved a compound, or salt of a catalytically active metal, or metals, to impregnate and deposit the metal, or metals, upon the support, or powder. The metal, or metals, impregnated support is calcined following each impregnation step to form oxides of the deposited metal, or metals.

Abstract: A process for the desulfurization, and reactivation of a sulfur deactivated catalyst constituted of cobalt composited with a titania support. The sulfur deactivated cobalt titania catalyst is first contacted with a gaseous stream of molecular oxygen at temperature sufficiently high to oxidize the sulfur component of the catalyst. The sulfur oxidized catalyst is next contacted with a liquid, preferably water, to remove the oxide, or oxides of the sulfur. The catalyst is then contacted with a reducing agent, suitably hydrogen, to restore the activity of the catalyst. During the treatment there is no substantial loss, if any, of cobalt from the catalyst.

Abstract: A process for detecting, and monitoring, changes in the properties of a fluidized bed of particulate solids, especially a fluidized bed of particulate catalytic solids at elevated temperature wherein a low molecular weight hydrocarbon is converted, in the presence of steam and oxygen, to synthesis gas. Measurement is made of the magnitude of differential pressure fluctuations taken at different levels of bed elevation and these are recorded as a standard deviation, or normalized standard deviation, and directly related to particle size changes caused by agglomeration (growth) and/or attrition (size reduction). Operation of the process requires the use of fast response pressure transducers that are located in the bed and connected to an A/D board of a PC which records and accumulates the data for processing, and analysis.

Abstract: The invention is a process for producing a mixture of Fischer-Tropsch product that is solid at ambient conditions (between 32° F. and 95° F.), such as wax, and hydrocarbon liquid, such as naphtha, that can be pumped at ambient temperature (between 32° F. and 95° F.). The temperature of the mixture is controlled below the melting point of the Fischer-Tropsch product. The present invention provides for the transport of Fischer-Tropsch product from a remote location in a readily available medium, such as naphtha, via pipeline, tanker or railcar. At the completion of the transport, the hydrocarbon liquid and Fischer-Tropsch product are separated by conventional methods such as flashing, distillation, or filtration with minimal contamination from the hydrocarbon liquid.

Abstract: Hydrocarbon in water emulsions comprising Fischer-Tropsch process water, at least 20 to about 90 weight percent of a Fischer-Tropsch wax, a first nonionic surfactant having an HLB of at least 11 and a second nonionic surfactant having an HLB less than 11. Said emulsions are liquid at room temperature and pour by ordinary gravity. Also disclosed are methods of making said hydrocarbon in water emulsions.

Abstract: A formulation of chemical surfactants, solvents and inorganic salts is effective for dispersing heavy oils in both salt and fresh water. The formulation comprises a mixture of a sorbitan ester of an aliphatic monocarboxylic acid, a polyoxyethylene adduct of a sorbitan monoester of an aliphatic monocarboxylic acid, an alkali metal salt of a dialkyl sulfosuccinate, a polyoxyethylene adduct of a sorbitan triester of a monocarboxylic acid, a solvent comprising a hydrocarbon and/or a glycol ether and an inorganic salt containing a soluble divalent cation such as calcium or magnesium.

Abstract: Lubricating oils useful as gear oils, circulating oils, compressor oils and in other applications characterized by and excellent balance of anti-wear and anti-rust characteristics are based on high quality base stocks including a major portion of a hydrocarbon base fluid such as a PAO with a secondary base stock component which is preferably a long chain alkylated aromatic, such as an alkylnaphthalene. A synergistic combination of additives comprising an adduct of a substituted triazole such as benzotriazole or a substituted benzotriazole, e.g. tolyltriazole (TTZ) with an amine phosphate and a trihydrocarbyl phosphate such as cresyl diphenylphosphate (CDP), confers the desired balance of anti-wear and anti-rust properties. In addition, the present oils typically include an anti-oxidant component and a rust inhibitor together with other optional additive components.
