Section: claims

1. A mass transfer apparatus, comprising:a housing and, provided therein, a flow reaction chamber filled with an oxidation agent, provided with an adjustable heating system, and systems for inlet and outlet of oxidizable material, wherein the housing is equipped with a repository for reserves of the oxidation agent. 2. The mass transfer apparatus according to claim 1, wherein an electric heater is used as an adjustable heating system. 3. The mass transfer apparatus according to claim 2, wherein a high resistance wire made of nichrome or fechral is used as a heating element. 4. The mass transfer apparatus according to claim 1, wherein the repository for reserves of the oxidation agent includes a bottom and a side wall, formed by a lower part of the housing. 5. The mass transfer apparatus according to claim 4, wherein openings are made in an upper part of the side wall of the repository for reserves of the oxidation agent, adjacent to the flow reaction chamber. 6. The mass transfer apparatus according to claim 4, wherein openings are made in a lower part of the side wall of the repository for reserves of the oxidation agent. 7. The mass transfer apparatus according to claim 1, wherein the repository for reserves of the oxidation agent is located below the flow reaction chamber. 8. The mass transfer apparatus according to claim 2, wherein the repository for reserves of the oxidation agent is located below a lower end of the electric heater. 9. The mass transfer apparatus according to claim 2, wherein, in an initial state, a volume of the repository for reserves of the oxidation agent is filled with the oxidation agent. 10. The mass transfer apparatus according to claim 1, wherein the flow reaction chamber is formed by a middle part of the housing, defined from below by an upper part of the repository for reserves of the oxidation agent, and from above, by a restrictive grille. 11. The mass transfer apparatus according to claim 10, wherein in the restrictive grille, there are openings provided. 12. The mass transfer apparatus according to claim 2, wherein the system for inlet of the oxidizable material is formed by an upper part of a side wall of the repository for reserves of the oxidation agent. 13. The mass transfer apparatus according to claim 1, wherein the system for outlet of the oxidizable material is formed by a restrictive grille of the flow reaction chamber and openings in a wall of the housing. 14. The mass transfer apparatus according to claim 13, wherein the system for outlet of the oxidizable material is located below the flow reaction chamber. 15. The mass transfer apparatus according to claim 1, wherein the oxidation agent is comprised of a solid-phase agent. 16. The mass transfer apparatus according to claim 1, wherein the produced oxidation agent is comprised of separate particles. 17. The mass transfer apparatus according to claim 1, wherein a granulated lead oxide is used as a solid-phase oxidation agent. 18. The mass transfer apparatus according to claim 5, wherein the openings are made in the form of a series of slits having a width lesser than a size of particles of a solid-phase oxidation agent. 19. The mass transfer apparatus according to claim 1, characterized in that it is located horizontally in the oxidizable material reservoir.
