An electrode material which may be used in an electrochemical cell used to convert carbon dioxide into useful products, such as synthetic fuel. The electrode material may comprise nano-sized core-shell catalyst (i.e., core-shell nanoparticles, or CSNs) having a catalytic core component encompassed by one or more outer shells, wherein at least one of the outer shells has a mesoporous structure. Electrochemical cells, electrochemical cell electrodes, and methods of making CSNs are also provided.

A process to convert paraffinic feedstocks into renewable poly-alpha-olefins (PAO) basestocks. In a preferred embodiment of the invention, renewable feed comprising triglycerides and/or free fatty acids are hydrotreated producing an intermediate paraffin feedstock. This paraffin feedstock is thermally cracked into a mixture of olefins and paraffins comprising linear alpha olefins. The olefins are separated and the un-reacted paraffins are recycled to the thermal cracker. Light olefins preferably are oligomerized with a surface deactivated zeolite producing a mixture of slightly branched oligomers comprising internal olefins. The heavier olefins (C8-C14) are oligomerized, preferably with a BF3 catalyst and co-catalyst to produce PAO products. The oligomerized products can be hydrotreated and distilled together or separate to produce finished products that include naphtha, distillate, solvents, drilling fluid, and PAO lube basestocks.

A process for making a fluorinated olefin having the step of dehydrochlorinating a hydrochlorofluorocarbon having at least one hydrogen atom and at least one chlorine atom on adjacent carbon atoms, preferably carried out in the presence of a catalyst selected from the group consisting of (i) one or more metal halides, (ii) one or more halogenated metal oxides, (iii) one or more zero-valent metals/metal alloys, (iv) a combination of two or more of the foregoing.

A method of preparing a bound zeolite support comprising: contacting a zeolite powder with a binder and water to form a paste; shaping the paste to form an wet extruded base; removing excess water from the wet extruded base to form an extruded base; contacting the extruded base with a fluorine-containing compound to form a fluorinated extruded base; calcining the extruded base to form a calcined fluorinated extruded base; washing the calcined fluorinated extruded base to form a washed calcined fluorinated extruded base; drying the washed calcined fluorinated extruded base to form a dried washed calcined fluorinated extruded base; and calcining the dried washed calcined fluorinated extruded base to form a bound zeolite support.
