The invention provides a pyrolysis reaction system, the system comprising: a pyrolysis chamber comprising a feed inlet, a gas inlet and a product outlet, wherein the pyrolysis chamber is configured i) to receive a pyrolysable organic feed and an inert gas via the feed inlet and gas inlet respectively, ii) to pyrolyse the organic feed at a pyrolysis temperature to produce a carbonaceous pyrolysis product and a pyrolysis gas, wherein the pyrolysis gas will combine with the inert gas to form a gas mixture having a pyrolysis chamber pressure in the pyrolysis chamber, and iii) to discharge the carbonaceous pyrolysis product via the product outlet; a gas reactor configured to react the pyrolysis gas by combustion and/or carbon deposition at a gas reaction temperature and a gas reactor pressure; and a first partition defining a boundary between the pyrolysis chamber and the gas reactor, the first partition comprising a plurality of first apertures to provide fluid communication between the pyrolysis chamber and the gas reactor, wherein the pyrolysis reaction system is operable with the gas reactor pressure less than the pyrolysis chamber pressure such that the gas mixture flows from the pyrolysis chamber to the gas reactor through the first apertures, thereby providing at least a portion of the pyrolysis gas for reaction in the gas reactor.

The present disclosure generally relates to the utilization of a fine mineral matter in the process of upgrading the liquid products obtained by thermolysis or pyrolysis of solid plastic waste or biomass or from cracking, coking or visbreaking of petroleum feedstocks. More particularly, the present disclosure is directed to a process of stabilization of the free-radical intermediates formed during thermal or catalytic cracking of hydrocarbon feedstocks including plastic waste and on a process of catalytic in-situ heavy oil upgrading. The fine mineral matter may be derived from natural sources or from synthetic sources.

Processes for controlling afterburn in a reheater and loss of entrained solid particles in reheater flue gas are provided. Carbonaceous biomass feedstock is pyrolyzed using a heat transfer medium forming pyrolysis products and a spent heat transfer medium comprising combustible solid particles. The spent heat transfer medium is introduced into a fluidizing dense bed. The combustible solid particles of the spent heat transfer medium are combusted forming combustion product flue gas in a dilute phase above the fluidizing dense bed. The combustion product flue gas comprises flue gas and solid particles entrained therein. The solid particles are separated from the combustion product flue gas to form separated solid particles. At least a portion of the separated solid particles are returned to the fluidizing dense bed.
