    摘要： A method for adsorbing and oxidizing VOC's in the same bed, thus reducing the size of or even eliminating the need for a catalytic or thermal oxidation unit at the end of the system. In this system, a catalyst is intimately interspersed with the adsorbent material. The catalyst oxidizes VOC's released during desorption when it reaches the ‘light off temperature,’ that is, the catalyst temperature necessary for oxidation to begin. As VOC's are desorbed, they are combusted by the catalyst in the same bed and also by their combustion, heat the bed to aid in the desorption of VOC's elsewhere in the bed.

    摘要： A VOC (volatile organic compounds) adsorbent material such as an alumino-silicate gel desiccant is treated with a masking agent to reduce its affinity for VOC's to a level that the material can be regenerated at a predetermined low temperature which will not desorb the masking agent. The treated adsorbent material is used to adsorb VOC's and is periodically regenerated with heated air. The treated adsorbent material may be used to adsorb VOC's from recirculated spray booth air while spraying a coating on a workpiece. Subsequent to spraying, the spray booth air is heated to above the VOC regeneration temperature to regenerate the adsorbent material and optionally to cure the applied coating. As the heated spray booth air is circulated through the adsorbent material, the previously adsorbed VOC's are desorbed. The desorbed VOC's may be destroyed by oxidizing, for example, with a catalyst.

    摘要： This invention relates to the production of chemically durable inorganic silicate coatings which are homogeneous, easy to apply, and exhibit essentially infinite shelf life. More specifically, this invention relates to the preparation of such coatings by incorporating a metal oxide (M.sub.x O.sub.y) wherein Y:X is at least 1.5, into a true aqueous solution of an alkali metal silicate, at least about 50% by weight of said alkali metal consisting of potassium, which will dry in air, i.e., be non-hygroscopic. Thereafter, upon drying and curing, a crystal phase precipitates in situ within the solution causing polymerization of the silica at the crystal interfaces and subsequently throughout the solution, thus yielding a durable coating consisting essentially of a crystal phase homogeneously dispersed in a silicate glassy matrix.
