摘要:
Oils from plants and animal fats are hydrolyzed to fatty acids for a Kolbe reaction. The invention relates to a high productivity Kolbe reaction process for electrochemically decarboxylating C4-C28 fatty acids using small amounts of acetic acid to lower anodic passivation voltage and synthesizing C6-C54 hydrocarbons. The C6-C54 undergo olefin metathesis and/or hydroisomerization reaction process to synthesize heavy fuel oil, diesel fuel, kerosene fuel, lubricant base oil, and linear alpha olefin products useful as precursors for polymers, detergents, and other fine chemicals.
摘要:
A method for the separation of diamond particle clusters into discrete diamond particles and/or into smaller diamond particle clusters comprising fewer diamond particles is disclosed. The diamond particle clusters are combined with at least one liquid phase organic or inorganic compound, or with a solution of at least one organic or inorganic compound in at least one solvent to form a reaction mixture. Mechanical means are then used to separate the diamond particle clusters into discrete diamond particles and/or into smaller clusters within the reaction mixture producing diamond particles with dangling bonds or free bonding sites on the surface of the diamond particles. The at least one organic or inorganic compound then reacts with these dangling bonds present on the diamond particle surface. The surfaces of the diamond particles are functionalised by the reaction with the organic or inorganic compounds and the diamond particles and/or smaller clusters produced are well dispersed in dry powder form, as well as in solution.
摘要:
Methods for producing hydrocarbon oils from algal biomass are provided. The algal biomass is hydrogenolysed under reaction conditions sufficient to produce a partially deoxygenated lipid-based oil. The algal biomass may be whole algal biomass, residual algal biomass, or both. The algal biomass is hydrogenolysed by liquefying the algal biomass in the presence of a hydrogenolytic catalyst in a hydrogen atmosphere at an elevated temperature and pressure to produce an organic phase containing the partially deoxygenated lipid-based oil, an aqueous phase, and a solid phase. The aqueous and solid phases may be removed from the partially deoxygenated lipid-based oil. The partially deoxygenated lipid-based oil is then substantially deoxygenated using a hydroprocessing catalyst to produce the hydrocarbon oil.
摘要:
A process has been developed for producing diesel fuel from crude tall oil. The process involves treating a renewable feedstock by hydrogenating and deoxygenating to provide a diesel boiling range fuel hydrocarbon product. If desired, the hydrocarbon product can be isomerized to improve cold flow properties. A portion of the hydrocarbon product is recycled to the treatment zone to increase the hydrogen solubility of the reaction mixture.

A process for preparing very high viscosity polyalphaolefins using an acidic ionic liquid oligomerization catalyst in the absence of an organic diluent and the products formed thereby.
摘要:
Novel fluid mixtures of specified hydrocarbons meeting an array of structural criteria are described. Linear hydrocarbons having terminal double bonds and internal segments of specified differing chain lengths separated by one or more carbon atom(s) each of which has a methylidene substituent make up one group of such compounds. Another group is alkenyl end-capped compounds of the first group. Third and fourth groups are products formed by hydrogenation of the first and second groups, respectively. The products, whether end-capped or not, and whether hydrogenated or not, have desirable lubricating properties such as suitable low pour points and/or low NOACK volatility and/or very high viscosity index and thus can be used as base oils or as components in formulating lubricants.
摘要:
A system and a method are provided for an axial flow through chemical reactor that provides for the separation of hydrogen from a hydrocarbon feedstock and to form longer chain hydrocarbon molecules. The system consists of a radial magnetic field and an axial electric field in a cylindrical device, and a method of exciting flow through gas molecules by means of Lorentz Force to cause centrifugal force on the gas stream in the radial direction, inducing high molecular sheer in the rotating gas stream causes hydrogen to be removed from the rotating gas column, high molecular density forces radical hydrocarbon molecules to combine in the absence of Hydrogen.
