    Title: A Survey of n-Alkane Precipitation Studies with Special Reference to Diesel Fuels

    Authors:
    Brečević, Ljerka (5334)
    Journal: Kemija u industriji
    Number: 4
    ISSN: 0022-9830
    Volume: 42
    Year: 1993
    Pages: from 95 to 103
    Number of references: 71
    Language: hrvatski
    Summary: Many fuel oils exhibit the inconvenient property of crystallizing in cold weather. In diesel fuels this problem results from a mixture of higher n-alkanes. In order to prevent crystallization a comprehensive knowledge of the constituents and processes involved is needed. In this paper, a literature survey of the higher n-alkane characteristics and behaviour, the processes involved in vax precipitation, and the effective additive characteristics and their influence on vax precipitation processes is given.

    Place: Varšava, Poljska
    Year: 1993
    Pages: from 4-059 to 4-064
    Meeting: 12th Symposium on Industrial Crystallization
    Held: from 09/21/93 to 09/23/93
    Summary: The interfacial energy is one of the main parameters governing the nucleation process. In the present studies the interfacial energy, derived from nucleation experiments, depended linearly on the mole fraction of tetracosane in decahydronaphthalene or dodecane solutions. Two mechanisms were found to exist for the nucleation of the tetracosane from solutions in dodecane while only one mechanism is suggested by the induction period measurements in decahydronaphthalene.

    Proceedings title: Industrial Crystallization '93
    Language: engleski
    Place: Varšava, Poljska
    Year: 1993
    Pages: from 4-119 to 4-124
    Meeting: 12th Symposium on Industrial Crystallization
    Held: from 09/21/93 to 09/23/93
    Summary: The dissolution of vaterite in water between 15 and 45 řC and at ionic strengths from 50 to 200 mM has been investigated. The reaction was followed by recording pH as a function of time. The dissolution rate, -dr/dt, was found to depend linearly on the undersaturation, c*-c, and was most probably determined by the diffusion of the constituting ions away from the crystals. The change with temperature corresponds to the activation energy, Ea=23.3 kJ/mol, typical for diffusion.
    Keywords: Vaterite, Calcium carbonate, Dissolution, Kinetics, Diffusion, Activation energy
