    • C.sub.2 -C.sub.4 halogenated, e.g., chlorinated and brominated, hydrocarbons, such as vinyl chloride, present in a gas stream are removed therefrom, e.g., incinerated, by contacting the gas stream with an oxygen-containing gas in the presence of cobalt oxide catalyst at relatively low temperatures, e.g., 100.degree. C. Commonly, the halogenated hydrocarbon is present in the gas stream to be treated in small amounts, e.g., less than 0.05 weight percent. The temperature of treatment can vary, e.g., from 20.degree. to 500.degree. C., and can be adjusted within said range depending on the relative humidity of the gas stream treated to maintain catalytic activity. Preferably, treatment occurs under conditions of low relative humidity, e.g., less than 5 percent, and the catalyst is a hydrated cobalt oxide catalyst.
    • 通过在氧化钴催化剂的存在下将气流与含氧气体接触,将存在于气流中的C 2 -C 4卤化例如氯化和溴化的烃例如氯乙烯从其中除去,例如焚烧, 相对较低的温度,例如100℃。通常,卤代烃以少量存在于待处理的气流中,例如小于0.05重量%。 处理温度可以变化,例如20℃至500℃,并且可以根据处理的气流的相对湿度在所述范围内调节以维持催化活性。 优选地,处理在低相对湿度(例如小于5%)的条件下进行,并且催化剂是水合氧化钴催化剂。

    • A thickening or suspending agent for imparting thixotropic properties to aqueous compositions, particularly LADD formulations, comprises a kaolinite clay admixed to the formulation at a level ranging from about 2% to about 5% by weight. While the thickening or suspending properties of the kaolinite clay are exhibited over a very broad range of particle size products, the kaolinite clay used advantageously has a particle size distribution of at least about 50% of the kaolin particles thereof have a particle size less than 2 microns equivalent spherical diameter, more preferably at least about 80% and, most perferably, at least about 95%. When utilized in a slurry form, the kaolinite clay based thickening or suspending agent most advantageously comprises an aqueous slurry of kaolinite particles at a solids level of at least 65% solids by weight. The thickening or suspending agent may also comprise a mixture of a kaolinite clay and a non-kaolinite selected from the group consisting of a smectite clay, attapulgite clay and mixtures thereof, preferably as a mixture of equal parts of kaolinite clay and attapulgite clay, and most preferably as a mixture of equal parts of a kaolinite clay and a bentonite clay.
