Abstract: A gasification system for the oxidation of a carbonaceous feedstock to provide a synthesis gas comprising: a reactor chamber for oxidizing the carbonaceous feedstock; a quench section for holding a bath of liquid coolant; an intermediate section having a reactor outlet opening through which the synthesis gas is conducted from the reactor chamber into the bath of the quench section; at least one layer of refractory bricks arranged on the reactor chamber floor, the lower end section of the refractory bricks enclosing the reactor outlet opening and defining the inner diameter thereof; the intermediate section including a number of halved tubes for liquid coolant arranged onto at least part of the reactor chamber floor on a side thereof opposite to the lower end section of the refractory bricks; and a pump system for circulating the liquid coolant through the halved tubes on the reactor chamber floor.

Abstract: A gasification system for the partial oxidation of a carbonaceous feedstock to at least provide a synthesis gas, the system comprising a reactor chamber and a quench section below the reactor chamber. An intermediate section connecting the reactor chamber to the quench section comprises at least one layer of refractory bricks arranged on and supported by the reactor chamber floor, the refractory bricks enclosing a reactor outlet opening. A membrane wall extends downwardly from the reactor outlet opening of the reactor chamber floor. A pump system is provided communicating with a source of a liquid coolant for circulating the liquid coolant through the tubes of the membrane wall.

Abstract: Catalytic cracking riser reactor extending between an inlet for hydrocarbonaceous feed and catalyst particles and an outlet for discharging cracked products and spent catalyst particles, which riser reactor has been provided with at least one contacting device, wherein the contacting device comprises a composite of refractory material and a metal structure, which metal structure is connected to the outer wall of the riser reactor. If more contacting devices have been provided, they are preferably axially spaced apart and are disposed along the inner surface of the riser reactor.
