MOBILE BIOMASS THERMOCHEMICAL ENERGY CONVERSION UNIT AND RELATED METHODS
A thermochemical energy conversion unit includes a heat expansion assembly including a reactor configured to receive a biomass and convert the biomass into a burnable gas having undesirable materials therein and a biochar. The heat expansion assembly also includes a heat expansion discharge pipe configured to discharge the burnable gas from the heat expansion assembly. The thermochemical energy conversion unit also includes a gas scrubber assembly operatively connected to the heat expansion assembly and configured to receive the burnable gas therefrom and to remove the undesirable materials from the burnable gas. The gas scrubber assembly includes a scrubber discharge pipe configured to discharge the burnable gas from the gas scrubber assembly. The heat expansion assembly and the gas scrubber assembly are configured to be continuously fluidly connected from the heat expansion discharge pipe to the scrubber discharge pipe for generating a continuous flow of the burnable gas therealong.

BIOPOWERPLANT: THIRD GENERATION BIOREFINERY WITH IMPROVED CAPACITY TO USE DOMESTIC WASTEWATER, LANDFILL LEACHATE AND SEA SALT WATER AS AN INPUT TO GENERATE GREEN ENERGY, WATER FOR REUSE, BIOFUEL, ORGANIC FERTILIZERS AND CAPTURE ATMOSPHERIC CO2
The Biopowerplant is a system that integrates the generation of carbon-neutral energy through the cultivation and conversion of microalgal biomass, with sewage sanitation and environmental carbon recovery, with the additional and secondary production of biofertilizer, biofuel, water for reuse. This system integrates a suboptimal anaerobic digestion subsystem focused on the generation of biogas, the processing of the resulting digestate through a microalgal consortium culture subsystem with biofilm induction and smooth decreasing gradient of light radiation, and the transformation of the generated microalgal biomass into syngas through a subsystem of evaporation, torrefaction, pyrolysis, gasification, and combustion in separate chambers. The syngas and methane from the biogas are subsequently used as fuel in an electric power generator capable of operating with mixed gases. The biogas generation process is enriched through the recirculation of the microalgal biomass supernatant, the residual heat from the syngas generation subsystem, and the heat transferred from the combustion gases of the electric generator. The residual sludge from the biogas generation subsystem is recirculated towards a longitudinal biopile subsystem, where it acts as an anaerobic medium compared to the aerobic medium that constitutes the concentrated microalgal biomass, and both streams are mixed to be transformed into the syngas generation subsystem. Input inflows for system operation are mainly sewage, and optionally seawater and/or leachate. The inflows must be bioaugmented with a microalgal consortium dosed automatically by a Compact in situ bioaugmentation system, preferably more than 3 kilometers before the inflow enters the system.
PROCESSES AND SYSTEMS FOR RECAPTURING CARBON FROM BIOMASS PYROLYSIS LIQUIDS
This disclosure provides a method of making a high-fixed-carbon material comprising pyrolyzing biomass to generate intermediate solids and a pyrolysis vapor; condensing the pyrolysis vapor to generate pyrolysis liquid; blending the pyrolysis liquid with the intermediate solids, to generate a mixture; and further pyrolyzing the mixture to generate a high-fixed-carbon material. A process can comprise: pyrolyzing a biomass-comprising feedstock in a first pyrolysis reactor to generate a first biogenic reagent and a first pyrolysis vapor; introducing the first pyrolysis vapor to a condensing system to generate a condenser liquid; contacting the first biogenic reagent with the condenser liquid, thereby generating an intermediate material; further pyrolyzing the intermediate material in a second pyrolysis reactor to generate a second biogenic reagent and a second pyrolysis vapor; and recovering the second biogenic reagent as a high-yield biocarbon composition. The process can further comprise pelletizing the intermediate material. Many process and system configurations are disclosed.
