  • Publication number: 20230279194
    Abstract: Process for upcycling a waste material to form alkylaromatic compounds is described herein. The process typically includes the steps of feeding a waste material containing hydrocarbon polymer(s) into a reactor containing a catalyst therein, and operating the reactor at a sufficient temperature for a sufficient period of time to convert the hydrocarbon polymer(s) to a liquid and/or wax product containing alkylaromatic compound(s). Each of the alkylaromatic compound(s) contains at least 10 carbon atoms. The catalyst contains a transition metal or a mixture of a transition metal and another metal. Optionally, the catalyst is dispersed on the surface of a support. The product may contain other unsaturated compounds, such as olefins. Typically, the reactor operates at a temperature in the range between 250° C. and 350° C. The total selectivity of the process to form the one or more alkylaromatic compounds is typically between 50 mol % and 95 mol %.

  • Publication number: 20220033341
    Abstract: A process for a reactive separation of organic molecules from biomass includes a reaction step for the biomass, a simultaneous extraction step using a solvent, and a filtration step to recover products, wherein the products comprise ferulic acid and/or coumaric acid. The products are extracted from the biomass in a pressurized stirred batch reactor using a liquid extraction solvent and a base in which the ferulate and the coumarate remain.

  • Patent number: 7700072
    Abstract: A novel application of a transition metal oxo complex, a cationic oxorhenium(V) oxazoline, in the production of molecular hydrogen (H2) from the catalytic hydrolytic oxidation of organosilanes. The reaction is characterized by quantitative hydrogen yields, low catalyst loading, ambient conditions, high selectivity for silanols, water as the only co-reagent, and no solvent requirement. The amount of hydrogen produced is proportional to the water stoichiometry. For example, reaction mixtures of polysilyl organics such as HC(SiH3)3 and water contain potentially greater than 6 weight percent hydrogen. Kinetic and isotope labeling experiments reveal a new mechanistic paradigm for the activation of Si—H bonds by oxometalates.
