    摘要： A method and apparatus for treating the exhaust gases of a combustion process, the exhaust gases comprising in part condensable or solidifiable particulate matter and residual hazardous organic compounds and emanating from the combustion process at a first temperature, by heating a portion of the exhaust gases using a heating means within a bypass means to a second temperature higher than the first temperature, maintaining the heated exhaust gases within the bypass means at the second temperature for a time sufficient to render the desired poriton of the residual hazardous organic compounds harmless, and then cooling the heated exhaust gases using a quench means within the bypass means to a third temperature lower than the first temperature in a period of time short enough to prevent the condensable or solidifiable particulate matter from condensing or solidifying on and adhering to the bypass means.

    摘要： A cementitious composition comprising 0.1 to about 7.5 percent by weight of a solid residual oxidation product from the combustion of an aqueous emulsion of a naturally occurring asphalt from the Orinoco Belt of Venezuela which contains from about 100 to about 1500 ppm by weight of magnesium in the form of a water soluble magnesium salt, which product from the combustion contains magnesium sulfate present in the amount of from about 0.05 to about 4 percent by weight of the cementitious composition and from about 92.5 to about 99.95 percent by weight of a hydraulic silicate cement material.
