In a method for producing pyrolysis oil, pyrolysis gas and pyrolysis coke, a starting material substantially comprising biomass is supplied to the upper region of a pyrolysis reactor. The latter has a substantially vertically arranged reactor chamber, which is substantially tubular. The reaction chamber then contains a bed of bulk material that comprises the starting material to be pyrolyzed and, optionally, the pyrolysis coke. This bulk material is thermally treated in the pyrolysis reactor, where the pyrolysis coke, the pyrolysis gases and the pyrolysis vapors are formed from the starting material to be pyrolyzed, and where the bulk material, the pyrolysis gases and the pyrolysis vapors are guided through the reaction chamber from top to bottom. The movement of the bulk material is caused substantially by gravity and the movement of the pyrolysis gases and pyrolysis vapors by the gas pressure building up.

A pyrolysis apparatus for solid hydrocarbon feedstock and a process method thereof are related to a pyrolysis apparatus and a process method thereof. A multi-tubular pyrolysis reactor of the apparatus is composed of one or more tubular pyrolysis reactors that are arranged in a tube-by-tube manner, its heating section being arranged in a heating chamber. A pyrolysis gas obtained from feedstock pyrolysis or an externally supplied fuel gas is combusted in the heating chamber through a regenerative combustion, so as to provide heat for the pyrolytic reaction. A gas collecting internal component is arranged at a center of each tubular pyrolysis reactor, and a pyrolysis gas product is regulated to radially flow across a moving particle bed so as to achieve in-situ filtering dust removal and selective cracking upgrading.

A fully modular assembled pyrolysis reactor with multiple feeding points includes modular upper and lower vessels. The lower vessel is equipped with a first biomass input unit, and inside the lower vessel, there is an integrated rotatable grate. The outlet end of the input pipe of the first biomass input device is formed at the top center of the grate, so that the grate's surface forms the core reaction zone of the pyrolysis reactor. The upper vessel is equipped with additional biomass input units, and the outlet end of the input pipe of the additional biomass input units extend into the core reaction zone of the pyrolysis reactor, with built-in cooling function and door switch. While achieving precise control, the technical problem of single feedstock in existing vertical pyrolysis reactor with bottom feeding is solved, and the use of multiple feedstocks can be immediately implemented, greatly improving operational stability.
