This invention provides processes and systems for converting biomass into high-carbon biogenic reagents that are suitable for a variety of commercial applications. Some embodiments employ pyrolysis in the presence of an inert gas to generate hot pyrolyzed solids, condensable vapors, and non-condensable gases, followed by separation of vapors and gases, and cooling of the hot pyrolyzed solids in the presence of the inert gas. Additives may be introduced during processing or combined with the reagent, or both. The biogenic reagent may include at least 70 wt %, 80 wt %, 90 wt %, 95 wt %, or more total carbon on a dry basis. The biogenic reagent may have an energy content of at least 12,000 Btu/lb, 13,000 Btu/lb, 14,000 Btu/lb, or 14,500 Btu/lb on a dry basis. The biogenic reagent may be formed into fine powders, or structural objects. The structural objects may have a structure and/or strength that derive from the feedstock, heat rate, and additives.

A plastic catalytic pyrolysis process that can produce high yields of ethylene, propylene and other light olefins from waste plastics is disclosed. The catalytic product stream is quenched to below catalytic pyrolysis temperature quickly after exiting the reactor or bulk separation from the catalyst. Quench preserves selectivity of light olefinic monomers. The catalytic pyrolysis process can be operated in a single stage or a two-stage process.

A method of continuously recovering hydrocarbons from carbon ores can include providing first and second vessels containing rubblized carbon ore. A cooling fuel gas can be introduced into the first vessel. The cooling fuel gas can include oxygen and a recycle gas from the second vessel, which includes hydrocarbons and oxidation products. The oxygen can be consumed through oxidation in an oxidation zone in the first vessel. The temperature of the oxidation zone can be controlled by limiting the oxygen concentration in the cooling fuel gas. This can produce a hot oxidation product gas that heats rubblized carbon ore in a pyrolysis zone downstream of the oxidation zone. Gaseous and vapor hydrocarbons can be produced in the pyrolysis zone. The vapor hydrocarbons can be condensed in a condensing zone downstream of the pyrolysis zone and then collected. The remaining gaseous hydrocarbons and oxidation products can be recycled as the recycle gas. The oxidation zone and the pyrolysis zone can continuously move through the rubblized carbon ore in a downstream direction. Optionally, by using nitrogen free oxygen for the oxidation, a nitrogen free stream of carbon dioxide is produced suitable for carbon dioxide capture and management. This can also eliminate the production of NOx in the oxidation process.

An arrangement for the recycling of carbon and hydrocarbon compounds from organic input material is provided. The arrangement includes: a reactor comprising a chamber that is limited by a jacket and upper and lower end-wall sections, gas inlet means for the supply of heated inert gas to the input material, whereby the gas inlet means is connected in a manner that transfers gas to a gas emission source, and gas outlets for leading the gas out of the chamber, where the gas outlet means comprises openings through which gas flows intended to supply the gas into the chamber, whereby the openings through which gas flows are arranged such that a fall in pressure is generated during the supply of gas that exceeds the fall in pressure of the gas during passage through the input material that has been introduced into the chamber. A corresponding method is also described.
