摘要： A method is disclosed for drying and passivating wet coals, for example bituminous, subbituminous or lignite. The wet coal is introduced into a heating zone at a controlled rate, then is contacted with a heavy hydrocarbonaceous treatment material having a softening point of at least 60.degree. C. The particles and treatment material are simultaneously intimately mixed and are heated to a temperature of at least 200.degree. C. but below the coal decomposition temperature while being moved along the heating zone in a plug flow manner. The particles are then cooled in a cooling zone.

摘要： The disclosure describes asphalt saturated felt building materials, optionally having a mineral filled asphalt base coating thereon, in which the asphalt saturating the felt and/or the asphalt in any mineral filled coating is a blend of 10-55% sulfur dispersed in the asphalt. The materials are used in the conventional manner as roofing felt, roofing shingles, and in built-up roofing, to obtain improved fire resistance.

摘要： The disclosure describes built-up roofing having improved resistance to spreading of fire, fabricated from two or more layers of felt impregnated with asphalt based saturant with asphalt based coating spread on top of each felt layer; the saturant asphalt or coating asphalt or both are blends of 90 - 45% asphalt with 10 - 55% sulfur. The roofing is built-up in the conventional manner by "mopping" fluid asphalt based coating onto felt layers impregnated with asphalt based impregnant. A protective layer of inert mineral aggregate (e.g. gravel) optionally covers the top coating.
