Abstract: A waste stream of organic matter such as sewage, plant and plastic matter is received for recycling and treated with high temperature and pressure to generate useful organic products such as bio-oil and gas. Byproducts such as char and an aqueous phase including water can be selectively recycled or beingly discarded. An oxidant added to a reactor containing waste from the waste stream facilitates an autothermal reaction under the temperature and pressure applied to the reactor, boosting the temperature slightly from the reactions therein. The reactor generates useful hydrocarbons such as bio-oil resulting from disruption of organic bonds. A combination of oxidation and radical initiation results from the oxidant, and provides an increased yield of bio-oil while decreasing char when compared to temperature and pressure alone. A stoichiometric quantity of the oxidant limits complete conversion of carbon into carbon dioxide by limiting available oxygen and therefore favoring hydrocarbon formation.

Abstract: The disclosed technology provides processes for producing hydrogen that is renewable, has negative carbon intensity, and is associated with net water production. The hydrogen is economically, environmentally, and socially superior to conventional hydrogen via steam reforming of natural gas or electrolysis of water. Some variations provide a process for manufacturing carbon-negative hydrogen and optionally activated carbon, comprising: feeding biomass into a first heated vessel or zone to generate dried biomass and a first recovered water stream; feeding the dried biomass into a second heated vessel or zone to pyrolyze the dried biomass, generating a biocatalyst and a biogas; feeding the biocatalyst, the first recovered water stream, and biogas to a third heated vessel or zone for biocatalytic conversion, thereby generating H2, CO, and optionally activated carbon; and recovering the hydrogen. The H2 is carbon-negative hydrogen characterized by a carbon intensity less than 0 kg CO2e per metric ton H2.
