Abstract
A method of forming a sidewall for a reactor for oxidizing volatile or semi-volatile organic compounds, the sidewall being reactive with gaseous oxidation products produced by the oxidation of the volatile or semi-volatile organic compounds, includes, i) providing a dry mixture of material comprising by weight: from about 23% to 35% cement; from about 30% to 45% added CaO; from about 6% to 20% added Ca(OH).sub.2 ; and from about 10% to 25% added CaSO.sub.4 ; ii) combining the dry mixture of material with water and forming a slurry therefrom; iii) forming the slurry into a desired reactor sidewall shape; and iv) hardening the shaped slurry into a hardened cement reactor sidewall. An apparatus for photochemically oxidizing gaseous volatile or semi-volatile organic compounds includes a reactor vessel comprising sidewalls having at least one baffle. The baffle comprises at least a portion of the respective reaction chamber sidewalls with the baffle itself comprising the dry porous cementitious and chemically sorbent material. The baffle includes a peripheral frame which receives the cementitious material. The frame has a peripheral and inwardly facing channel member having at least two channel walls. The channel walls include at least one projection extending into the cementitious material. A source of ultraviolet light used to produce the oxidation products are U-shaped tubes. A cooling medium used to cool the baffle comprises tubing mounted to a substantially planar substrate.
