A pyrolysis reactor has a feed system which includes one or more circularly arcuate feed tubes removably inserted through the outer wall of the reactor. Each feed tube is slidably disposed in a corresponding circularly arcuate external guide sleeve for positioning the discharge end of each feed tube at a predetermined location and orientation within the reactor. A hot particulate material normally suspended in a fluid carrier is fed into the reactor. The inlet end(s) of the feed tube(s) can be connected to a source of particulate agglomerative carbonaceous material suspended in a fluid carrier for injection into the reactor, preferably at a location where the hot particulate material is uniformly distributed throughout the cross-section of the reactor. Means can be provided to cool the particulate agglomerative carbonaceous material during transit through the feed tube(s) to prevent agglomeration in the feed tube(s).

Feed system for pyrolysis reactors

A knockout pot for separating pyrolysis oil and heavy hydrocarbon constituents from gaseous constituents in the vapor discharge from a flash pyrolysis process. The knockout pot includes a closed vessel having an inlet pipe extending vertically through the top of the vessel to the interior, the pipe having a plurality of discharge holes in the lower end of the inlet pipe. A quench liquid input is connected tangentially to the inlet pipe on the outside of the vessel, imparting a swirling motion to the quenching liquid. The quench liquid is withdrawn from the vessel and recirculated.

Method and apparatus for condensing pyrolysis oils

In a rotary feeder, a sealing surface on the end of each compartment defining radial wall is closely spaced from the peripheral surface of the rotor cavity in the housing, a distance that establishes controlled laminar fluid flow between compartments. Preferably, the sealing surface has an approximately uniform spacing from the peripheral surface of the cavity and a matching curvature, and is formed on a blade at least as wide as the radial wall.
