Abstract: A method for powering a diesel engine with a fuel emulsion involves preparing the fuel emulsion by emulsifying a fuel and water in the presence of an emulsifier package, which contains an anionic surfactant selected from sulfates and sulfonates. The emulsifier package for emulsifying a fuel and water and the fuel emulsion for powering a diesel engine are also provided.
Abstract: A fuel emulsion for powering a diesel engine contains water, a fuel, and an emulsifier package containing a quaternary ammonium surfactant. A method for powering a diesel engine with the fuel emulsion involves preparing the fuel emulsion by emulsifying a fuel and water in the presence of the emulsifier package. An emulsifier package for emulsifying a fuel and water contains a quaternary ammonium surfactant and at least one nonionic surfactant, which is an alkoxylate. The quaternary ammonium surfactant is obtainable by reacting a quaternizable nitrogen compound containing at least one quaternizable, especially tertiary, amino group with a quaternizing agent, which converts the at least one quaternizable, especially tertiary, amino group to a quaternary ammonium group, where the quaternizing agent is a hydrocarbyl epoxide in combination with a free hydrocarbyl-substituted polycarboxylic acid.

Abstract: A process for producing particles of a thermoplastic polymer in spherical form involves providing at least one thermoplastic polymer in a molten state and providing an aqueous solution of at least one surface-active substance. The aqueous solution is in a temperature range from 100 to 300° C. The process also involves dispersing the thermoplastic polymer in the aqueous solution to obtain an aqueous solution containing dispersed thermoplastic polymer, which is cooled down to a temperature below the solidification point of the thermoplastic polymer to obtain a suspension containing an aqueous solution and particles of the thermoplastic polymer suspended in a solid state and in spherical form. The particles can be separated from the suspension and, optionally, dried. The particles obtained from the process have a particle size distribution having a d[4,3] value of more than 10 ?m and a d90.3 value of more than 20 ?m.

Abstract: In a method of measuring parameters of superabsorbents, the absorption capacity of superabsorbents is determined under pressure, by reducing the pressure applied to a sample of the superabsorbent stepwise and determining the absorption capacity at each pressure. In addition, the rise in absorption capacity after a reduction in pressure is measured as a function of time and this is used to calculate the swelling constant k or the characteristic swelling time ?. Swelling constant or characteristic swelling time or the magnitude of the difference in absorption capacity at two different pressures are used to determine further parameters of the superabsorbent.
