Reactor for recovery or recycling of hydrocarbon products from hydrocarbon-containing material by decomposing and gasifying the material in a reactor housing, comprising a gas/particle separator device arranged to separate solid particles accompanying the gas and to return these particles directly to the reactor housing in the opposite direction to axially flowing gasified hydrocarbon products, and/or comprising a rotor shaft with axially running channels which are in flow communication with a coolant, and/or comprising a radial play formed between the periphery of a rotor and the inside of the reactor housing and amounting to at least 3 cm and at most 6 cm.

A process for making a biochar composition by passing renewable organic-carbon-containing feedstock through a beneficiation sub-system to reduce water content followed by introducing beneficiated feedstock into an oxygen-deficient thermal sub-system to result in renewable processed biochar having an energy density of at least 17 MMBTU/ton (20 GJ/MT) a water content of less than 10 wt %, and water-soluble salt that is decreased by at least 60 wt % on a dry basis from that of the unprocessed organic-carbon-containing feedstock.

A poly(vinyl acetal) composition, such as a poly(vinyl butyral) composition or resin, can be made containing recycle content by the use of a recycle content aldehyde composition as a feedstock to make the PVA or by application of a recycle allotment, such as an allocation or credit, applied to either the aldehyde composition or to the PVA composition. The recycle content is obtained by cracking a recycle content pyrolysis oil to make a variety of olefins, such as propylene or ethylene.
