    摘要: This invention provides a process for repairing and surfacing broken asphalt pavements which involves applying to the distressed pavement a binder composition which has exceptional solvating power for asphaltic material, and which functions to solubilize and incorporate aged pavement asphalt into the binder composition as it penetrates and fills void spaces.Illustrative of a preferred binder composition which is applied to the distressed pavement is a homogeneous blend of (1) a FCC main column bottoms residuum boiling above about 650.degree. F., and (2) an asphalt-soluble elastomer which improves the elasticity and wear resistance of the binder composition.

    摘要: A continuous and regenerative process for removal and destruction of VOC from effluents is disclosed. The process employs two fixed bed reactors in series filled with adsorbent/catalyst. The VOC containing effluent is passed over the first reactor for adsorbing VOC, while the second reactor, which is loaded with VOC from the previous cycle is regenerated with part of the treated gas made up with an appropriate amount of air. Just before the VOC breakthrough occurs at the first reactor, the roles of the two reactors are switched. The process is characterized by simple design, high VOC removal efficiency, no external heat requirement and low operation cost.

    摘要: Acidic halides, especially chlorides, are removed from a dry fluid stream by contact with dry particles of solid caustic. The solid caustic particles are preferably non-porous, and disposed as a fluidized bed. Salts deposit on the surface of the caustic and are physically removed, preferably by attrition, to regenerate the surface of the solid caustic. An dry, slightly alkaline salt can be the only product of neutralization. Salt coated beds of solid caustic can also be regenerated for reuse by attrition removal of salt deposits.

    摘要: Acidic halides, especially chlorides, are removed from liquid hydrocarbons such as catalytic reformate by contact with solid caustic such as a bed of NaOH pellets covered with a thin film of brine. Hydration of reformate improves removal when large amounts of chlorides are present in reformate. Halides in liquid hydrocarbon are recovered as a brine phase, which can be only slightly alkaline. Hydration of reformate can be controlled based on pH of brine removed from the bed.

    摘要: Acidic halogens, especially chlorides, are removed from a dry gas stream by contact with dry particles of solid caustic. The solid caustic particles are preferably non-porous, and disposed in a bed with at least a 10% bed interstitial volume. Limiting halogen content in gas, and operating with a bone dry gas, ensures that salts deposit on the surface of the solid caustic without plugging the bed of solid caustic. Efficient halogen removal can be achieved even when treating a bone dry gas, one having less than 10 ppmv water vapor, at ambient temperature, without plugging the bed.
