摘要： The present invention provides for a method of making storage stable road paving binders by blending a minor amount of a polymer having at least one diene monomer with a major amount of asphalt containing at least 0.3% by weight of total nitrogen at an elevated temperature such that the components are sufficiently fluid to blend; treating the asphalt-polymer blend using not more than 250 meq of a sulfonating agent per 100 g of asphalt-polymer blend to introduce the corresponding acid functionality into the blend; maintaining the sulfonated asphalt-polymer blend at a sufficiently elevated temperature and stripping the sulfonated blend with sufficient chemically unreactive gas to remove a major fraction of the acid functionality introduced by sulfonation. The invention also provides for the compositions made by the process. These are useful as binders in road paving applications.

摘要： The present invention provides a method of making storage-stable road paving binders by blending a minor amount of an unsaturated polymer (e.g., having at least one diene monomer) with a major amount of asphalt at an elevated temperature such that the components are sufficiently fluid to blend; treating the asphalt-polymer blend with a sulfonating agent; and stripping the treated asphalt-polymer blend at an elevated temperature with sufficient stripping gas to remove strippable sulfur moieties and to stabilize the resulting stripped, treated blend. The invention also provides asphaltic compositions made by the method. The asphaltic compositions are useful as binders in road paving applications.

摘要： Paving binders, especially hot mix paving mixtures, having excellent storage stability, reduced binder runoff, and high temperature viscosity are formed by adding a copolymer of ethylene with an alkyl acrylate or vinyl acetate and a neutralized sulfonated polymer to the asphalt. Preferably, the alkyl acrylate is methyl acrylate and the neutralized sulfonated polymer is a terpolymer of ethylene, propylene, and a diene monomer.

摘要： In a coal gasification operation or similar process carried out in the presence of an alkali metal-containing catalyst wherein spent solids containing ash and alkali metal catalyst residues are produced, alkali metal constituents are recovered from the spent solids by first removing magnetic constituents from the solids, contacting the solid particles from which magnetic constituents have been separated with an acid solution to extract alkali metal constituents from the solids and produce a spent acid solution enriched in alkali metal salts, raising the pH of the enriched solution sufficiently to precipitate aluminum from the solution as aluminum hydroxide, heating the remaining solution to precipitate silicon compounds, and recovering an enriched alkali metal solution from which aluminum and silicon compounds have been removed. This process permits the effective recovery of alkali metal catalyst constituents, eliminates iron compounds and other inactive constituents which may otherwise tend to build up in the catalyst system, and makes possible the recovery of aluminum as a valuable by-product of the process.
