Processes for chemically treating polyaromatic feedstock to form aromatic-containing oligomers or polymers are provided. The processes are characterized by treatment of a plurality of different polyaromatic hydrocarbon molecules and/or polyheterocyclic molecules present in polyaromatic feedstock with a first reagent so as to functionalize the molecules. Further treatment in a second step affords oligomeric or polymeric products which may be crosslinked. The products may be thermoplastic or thermoset materials and may find use in, for example, infrastructure applications, composites, fillers, fire retardants and 3-D printing materials.

Mitigation of catalyst inhibition in olefin polymerization

Methods are provided for processing glycerides to form lubricant boiling range molecules in a single reactor and/or a single reaction zone. The glycerides are exposed to catalysts that are stable under the conditions present in the reaction zones during conversion of glycerides to fatty ketones via a coupling reaction in the presence of a first catalyst, and the subsequent deoxygenation and isomerization of the ketones in the presence of a second dewaxing catalyst. The glyceride-containing feedstock can further include free fatty acids or fatty acid derivatives that can also be used for formation of ketones and subsequent deoxygenation and isomerization. In some configuration, the processing can occur in a single reaction zone containing mixed beds of the first and second catalyst. Such configurations can be used to control the ratio of diesel boiling range molecules versus lubricant boiling range molecules generated by the methods.

Oil-in-oil compositions and methods of making

Solid, waxy 1-olefins may be converted to low viscosity liquid products by carrying out a double bond isomerization in the presence of a solid acidic catalyst such as an acidic clay or a zeolite under mild conditions. The olefin isomer products are useful in the formulation of well fluids such as drilling muds, especially useful in offshore drilling. The preferred oils for making up the well fluids are formulated with a hydrocarbon oil blend of the low viscosity olefin isomer together with a C.sub.12 to C.sub.18 paraffinic hydrocarbon of petroleum origin and a C.sub.10 to C.sub.32 olefin such as tetradecene-1. The fluids exhibit good biodegradability and are non-toxic to marine organisms; they also meet viscosity and pour points specifications for formulation into oil based muds.
