  • Patent number: 11608450
    Abstract: A process for a continuous condensation reaction with feedstocks derived from bio-renewable resources, e.g., pine chemical derived feedstock, is disclosed. The process employs at least a multi-stage mixing reactor, selected from any of a multi-stage continuous stirred tank reactor (CSTR), a multi-stage horizontal continuous stirred tank reactor (HCSTR), or a continuous oscillating baffle reactor (COBR). The multi-stage mixing reactors are provided with a plurality of baffles for creating a mixing in a number of stages or cells created by the baffles, allowing the condensation reaction to proceed at a production rate at least twice that of a batch process with reactors of equivalent volume. The feedstocks derived from bio-renewable resources is selected from gum rosin, wood rosin, tall oil rosin and mixtures thereof; and polymeric fatty acids derived from bio-renewable resources such as tall oil.

  • Publication number: 20220332574
    Abstract: A flow reactor system for providing on-demand H2 evolution at pressure from a liquid organic hydrogen carrier and/or blends thereof includes a reactor that includes a reaction vessel having an inlet and outlet. The inlet is configured to introduce reactants into the reaction vessel, and the outlet is configured to release reaction products. The reaction vessel is configured to hold therein a catalyst system capable of catalyzing the evolution of molecular hydrogen from a liquid organic hydrogen carrier. Advantageously, the reaction vessel is configured to operate at pressures greater than or equal to 50 psig (e.g., from about 50 psig to about 10500 psig. The flow reactor system also includes a source of preheated liquid organic hydrogen carrier in fluid communication with the reactor and a purification system in fluid communication with the outlet that provides purified molecular hydrogen gas for on-demand applications.
