    摘要： A process for the conversion of natural gas into higher hydrocarbons, which comprises the following steps:

    (i) reacting natural gas with steam in at least one reforming zone containing a reforming catalyst to produce a first product stream containing carbon monoxide, carbon dioxide and hydrogen;
    (ii) passing said first product stream, without separating said carbon dioxide, to a Fischer-Tropsch reactor to produce a second product stream including hydrocarbons and carbon dioxide;
    (iii) passing said second product stream to a recovery zone where the desired higher hydrocarbon products are recovered, the remaining components of said second product stream forming a third product stream;
    (iv) passing at least a portion of said third product stream into the reforming zone of process step (i).

    摘要： A method for recovering the surfactant from a dispersion or emulsion of oil and water containing a temperature sensitive surfactant which method comprises the steps of heating the dispersion or emulsion to a temperature above the cloud point of the surfactant under conditions of temperature and aqueous phase salinity such that the dispersion or emulsion breaks and separates into an oil layer, an aqueous layer and a surfactant layer, and recovering the surfactant layer. The recovered surfactant may be recycled for use in preparing further quantities of dispersion or emulsion, thus rendering the operation more economic.

    摘要： An aqueous aluminum phosphate solution, comprising component (i) mono aluminum tris(dihydrogen phosphate) and component (ii) a salt of a metal selected from the group consisting of alkali metals, alkaline earth metals and aluminum and mixtures thereof, and an acid at least as strong as phosphoric acid, with the proviso that if the said metal consists of aluminum, then said acid is stronger than phosphoric acid and (iii) phosphoric acid. The phosphate solution is used to react with a metal oxide curing agent in the presence of an aggregate to form a set cement.

    摘要： Uranium is extracted from wet process phosphoric acid by extraction with a mixture of a diorganophosphate and a neutral phosphorus compound, which is preferably triorgano phosphine oxide, in the presence of nitrate to form an organic extract layer containing uranium and an aqueous acid layer, which are separated.
