A method of processing a volatile organic compound is provided, wherein a volatile organic compound contained in gas to be treated is adsorbed in an adsorbent; the thus-adsorbed volatile organic compound is desorbed with the aid of steam and mixed in the steam; and the steam containing the volatile organic compound is combusted. This method further includes: separating a vessel for the adsorption and desorption into an inner side room and an outer side room by means of a separation member part of which is formed of the adsorbent; thermally retaining the vessel for the adsorption and desorption; at the time of adsorption, supplying the gas to be treated to the inner side room and therefrom to the outer side room; and at the time of desorption, supplying the steam to the outer side room and therefrom to the inner side room.

What is claimed is: 1. A method of processing a volatile organic compound, comprising: adsorbing in an adsorbent a volatile organic compound contained in gas to be treated; desorbing the thus-adsorbed volatile organic compound with the aid of steam and mixing it in the steam, under a pressurized state; and combusting the steam containing the volatile organic compound in a combustor, said method of processing further comprising: separating a vessel for the adsorption and desorption into an inner side room and an outer side room by means of a separation member part of which is formed of the adsorbent; thermally retaining the vessel for the adsorption and desorption; at the time of adsorption, supplying the gas to be treated to the inner side room and therefrom to the outer side room through the separation member; and at the time of desorption, supplying the steam to the outer side room and hence to the inner side room through the separation member. 2. The method as recited in claim 1, wherein the vessel for the adsorption and desorption is covered with a fluid having a predetermined temperature such that the vessel is thermally retained. 3. The method as recited in claim 2, wherein the fluid includes discharge gas of the combustor. 4. The method as recited in claim 1, wherein, after completion of the adsorption, the vessel is heated by supplying high-temperature compressed air and steam mixed gas to the inside of the vessel. 5. The method as recited in claim 4, wherein, when the ambient temperature of the adsorbent reaches to a predetermined level, the supply of the mixed gas is stopped. 6. The method as recited in claim 4, wherein, when the ambient temperature of the adsorbent reaches to a predetermined level and when a drain formed of the steam being condensed is reevaporated, the supply of the mixed gas is stopped. 7. The method as recited in claim 4, wherein, at the time of the heating, the mixed gas is supplied to the outer side room and then through the separation member to the inner side room. 8. The method as recited in claim 4, wherein, after completion of the desorption, the vessel is cooled by supplying air to the inside of the vessel. 9. The method as recited in claim 4, wherein, at the time of the cooling, the air is supplied to the inner side room and then through the separation member to the outer side room. 10. An adsorption and desorption apparatus, wherein a volatile organic compound contained in gas to be treated is adsorbed in a predetermined adsorbent, and the thus-adsorbed volatile organic compound is desorbed with the aid of steam and then mixed in the steam under a pressurized environment, said adsorption and desorption apparatus comprising: a vessel for the adsorption and desorption; a separation member part of which is formed of the adsorbent and by means of which the vessel is separated into an inner side room and an outer side room; and a heat retainer to thermally retain the vessel, wherein the gas to be treated is supplied to the inner side room and therefrom through the separation member to the outer side room, and the steam is supplied to the outer side room and then through the separation member to the inner side room. 11. The adsorption and desorption apparatus as recited in claim 10, wherein the heat retainer includes a jacket with which the vessel is covered and a fluid having a predetermined temperature which flows through the jacket and the vessel. 12. A system for processing a volatile organic compound, comprising; the adsorption and desorption apparatus as recited in claim 10; and a combustor in which the steam containing the volatile organic compound is combusted. 13. The system as recited in claim 12, wherein a fluid which flows in the heat retainer is discharge gas of the combustor.
