A supported catalyst system is based on a transition metal carbene including the moiety M1=CR*)2, wherein M1 is the transition metal and R* is hydrogen or a C1-C8 hydrocarbyl. The catalyst system can be supported on a metal oxide support such as silica or the catalyst can be self-supporting. Methods of making the catalyst system can involve precursors based on and/or reacted with aluminum alkyls, halides, and/or alkoxides. Methods of polymerizing cyclic olefins with the catalyst system can ob…

The present disclosure relates to processes for producing biofuel compositions by processing hydrocarbon co-feed and a bio-oil obtained via hydrothermal liquifaction (HTL) of a cellulosic biomass to form an HTL oil. The cellulosic mass can be processed at an operating temperature of about 425° C. or less and an operating pressure of about 200 atm or less. The HTL oil is co-processed with a hydrocarbon co-feed (e.g., petroleum fraction) in a cracking unit, such as an FCC unit, a coker unit or …
