NOVEL REACTOR FOR CARRYING OUT REACTIONS AT VERY HIGH TEMPERATURE AND HIGH PRESSURE,

摘要

pA reactor for carrying out high temperature and pressure reactions, at up to 1600[deg] C and up to 100 bars, has a reaction zone (Z) enclosed by a inner chamber (I) of refractory material (3), within a metal-walled outer chamber (II) filled with insulating material and enclosing an integrated heat exchanger (E) for cooling reaction effluents and preheating reactants. The chambers also have various inlet, outlet and connecting tubes. A reactor for carrying out high temperature and pressure reactions, at up to 1600[deg] C and up to 100 bars, comprises: (A) a reaction zone (Z), defined by an internal wall (4) and enclosed by a inner chamber (I); (B) the inner chamber, of refractory material (3), defined by a metal internal surface (2) and the internal wall and having inlets (7, 11) for the parts of the reactants and an effluent outlet tube (5) continuing from the central tube (10) of an integrated heat exchanger (E); (C) an outer chamber (II) filled with insulating material, located between the metal internal surface and an outer metal casing (1) and enclosing the heat exchanger for cooling reaction effluents and preheating reactants; (D) the outer casing, enclosing the other components and having at least two reactant inlet tubes, i.e. a tube (8) connecting with the heat exchanger and a tube (9) continuing from the inlet (11) and connecting with the reaction zone, plus at least one effluent outlet tube (12); (E) the charge-effluent heat exchanger, contained within the outer chamber, connected to the inlet tube (8) for part of the reactants and the effluent outlet tube (12) and connecting with the reaction zone via an internal tube (7); and (F) a regulator for the pressure difference between the inner and outer chambers. Independent claims are included for partial oxidation or combustion processes using the reactors, in which: (1) (a) combustion supporter (E1) is introduced via the inlet tube (8), preheated in the heat exchanger (E), introduced into the tube (7) and contacted with fuel (E2) introduced via the inlet tube (9); (b) the combustion supporter-fuel mixture is directed via the inlet (11) into the reaction zone (Z), in which the reaction is carried out; (c) the reaction effluents leave via the outlet tube (5), pass through the heat exchanger via the central tube (10), lose heat to the combustion supporter and leave the reactor via the outlet tube (12); and/or (2) the interior of the reaction zone is at 1000-1600[deg] C and 50-100 bars./p[FR2924358A1]
