The present disclosure provides a process for converting plastic comprising a polyolefin polymer to a lubricant. The process comprises contacting the plastic with a catalyst represented byA/[RQ].

Catalytic hydroconversion of polypropylene-based plastic waste to lubricant base-oils

Disclosed herein are systems and methods of depolymerizing a lignin component of a lignin-containing material. The method comprising contacting the lignin-containing material with a solvent and optionally a catalyst at a temperature in the range of 180-300° C. and at a maximum operating pressure of less than 10 barG during the depolymerization of the lignin component of the material and collecting at least one volatile stream comprising one or more depolymerized lignin products. In an embodiment, the step of contacting is carried out in a reactive distillation reactor, and the step of collecting comprises concurrently collecting at least one volatile stream via distillation apparatus connected to the reactive distillation reactor, at least one of the one or more depolymerized lignin products comprises a substituted phenol having the following general formula: (I) wherein Ris H, methyl, ethyl, n-propyl, propenyl, or allyl, and Rand Rare independently selected from H or methoxy group.

Low-pressure depolymerization of lignocellulosic biomass

The present disclosure provides a catalyst represented by Formula (I)X[(RO)(QO)]*Z  (I),wherein the moiety X[(RO)(QO)] and the moiety Z are mechanically mixed; wherein the weight percentage of the moiety Z is about 1% to about 99% of the total weight of the catalyst. Furthermore, the present disclosure provides a tunable, low-temperature, energy-efficient process for hydrocracking plastics to form a fuel, a lubricant, or a mixture thereof.

Hydrocracking catalysts and uses thereof

Disclosed herein is a bio-based copolymer comprising in polymerized form (i) at least one polymerizable bio-based monomer containing one phenolic hydroxyl group which has been derivatized to provide at least one polymerizable functional group which is an ethylenically unsaturated functional group (such as a [meth]acrylate group), where the precursors of the polymerizable bio-based monomers are derived from raw lignin-containing biomass, and (ii) at least one ion-conducting co-monomer other than the bio-based monomer. Also disclosed herein are binders comprising the bio-based copolymer, electrodes comprising the binder, polymer electrolytes comprising the bio-based copolymer and an electrochemical device comprising an electrode in electrical contact with a polymer electrolyte, wherein at least one of the electrode and the polymer electrolyte comprises the bio-based copolymer.

Ion-conducting bio-based polymers from raw lignocellulosic biomass

Disclosed herein is a method of making polymerizable bio-based monomers containing one phenolic hydroxyl group which has been derivatized to provide at least one polymerizable functional group which is an ethylenically unsaturated functional group (such as a [meth]acrylate group), where the precursors of the polymerizable bio-based monomers are derived from raw lignin-containing biomass. Also disclosed herein are bio-based copolymers prepared from such bio-based monomers and a co-monomer, and methods of making and using such bio-based copolymers. In particular, the bio-based copolymers can be used as pressure sensitive adhesives, binders, and polymer electrolytes.

Bio-based polymers from raw lignocellulosic biomass

A method of converting a lignocellulosic biomass to monosaccharides, and optionally further converting the monosaccharides to one or both of furfural and HMF, includes contacting the biomass with a reactive liquid phase comprising LiBr, HSO, and water, wherein HSOpreferably constitutes at most 1.0 wt %, more preferably at most 0.5 wt %, and most preferably at most 0.1 wt % of the reactive liquid phase, and water preferably constitutes at most at most 60 wt %, more preferably at most 50 wt %, and most preferably at most 30 wt % of the reactive liquid phase.

Integrated process for direct saccharification and dehydration of intact biomass to furfurals

The present invention comprises a device which utilizes catalytic microcombustion for the production of heat or power and which exhibits a low pressure drop and has a high catalytic surface area. The catalytic microcombustor includes catalyst inserts in the reaction chamber separated by a sub millimeter distance. Thermal spreaders ensure temperature uniformity and maximum thermal efficiency. A mixing zone is prior to the combustion zone. Thermally conductive and/or insulating inserts are in the vicinity of the reaction zone.
