Adsorption isotherms of hydrogen and nitrogen on silica gel were determined up to equilibrium pressures of approx. 800 mm mercury and at temperatures between +300 and —195°C. The adsorption of nitrogen-hydrogen mitxures at a total equilibrium pres

The adsorption of a model compound and of oil components on lime, clay and organic soil components is discussed. It is demonstrated that adsorption may reduce the total amount of oil transport to groundwater, reduce concentrations and delay transport

Hazes were produced by cooling liquid hydrocarbon mixtures containing dissolved water. Turbidities at various wavelengths in the visible region are indicative of initially monodisperse systems, which become heterodisperse later on. On the basis of tu

It is well-known that oil spills in soils after some time become immobile. Subsequent rainfall may then leach out water-soluble components, which are carried downward by the rainwater. In laboratory experiments a pack of non-adsorbing glass particles

1. 1. The degree to which hydrocarbons prevent flocculation of finely-divided carbon black in hydrocarbon medium was determined. 2. 2. Only aromatic hydrocarbons with aliphatic chains of sufficient length were found to stabilize the dispersion. Their

1. 1. Isotherms have been determined at room temperature for adsorption on carbon black of alkylated and non-alkylated aromatic compounds in n-heptane and white mineral oil. 2. 2. The results obtained suggest that the aromatic nuclei are adsorbed fla

1. 1. The viscosities were determined of 1–40% solutions of a mixture of sodium naphtha sulfonates in various hydrocarbons and mineral oils. The voluminosity ( V ) of the sulfonate in the solutions was calculated from the relative viscosity of the

From the viscosities of oil-in-water emulsions of varying particle size and concentration (prepared with the same oil and emulsifier) an apparent increase in oil concentration during flow was derived. The particle sizes were calculated from light-sca

1. 1. The distribution of some sodium alkyl benzene sulfonates over oil droplets and water phase in emulsions was determined by measuring the surface tensions of the emulsions. The emulsions were formed from white mineral oil/sulfonate systems either
