摘要： A process for purifying an aqueous, hydrogen sulfide-scrubbing solution which contains a water-soluble transition metal component, such as a vanadium component or an iron component, in addition to at least one water-soluble organic compound, such as an aromatic sulfonate or an alkanolamine, in which the scrubbing solution is mixed with particles of a spent solid catalyst containing molybdenum and aluminum and a basic aqueous solution, preferably a solution comprising sodium aluminate, to form a slurry which is subsequently contacted with an oxygen-containing gas under conditions such that the molybdenum in the catalyst is solubilized. Thereafter, molybdenum is precipitated from the solution along with the water-soluble transition metal component and a wastewater substantially free of the transition metal component and the organic compound originally present in the scrubbing solution is recovered.

摘要： A petroleum sulfonate is prepared by (a) separately sulfonating each of two or more different petroleum fractions boiling substantially above 700.degree. F. by contact with sulfur trioxide under reaction conditions wherein the ratio of milliliters of sulfur trioxide to grams of aromatic components is adjusted so as to produce from each separate fraction a reaction product capable of producing upon neutralization a sulfonate having a sulfonate requirement in microemulsion below about 20 grams per 100 milliliters of microemulsion; (b) separately neutralizing the sulfonated fractions; and (c) blending the hydrocarbon sulfonates produced from two or more of the fractions in proportions sufficient to yield a product petroleum sulfonate blend useful for enhanced oil recovery.In one embodiment four different petroleum fractions are separately sulfonated using different ratios of sulfur trioxide to aromatic content for each fraction and the sulfonated fractions are blended in a weight ratio between 0:1:1:0 and 1:10:10:1 to yield a sulfonate blend useful for enhanced oil recovery.
