| Popis: | In order to elucidate the mechanism of nonpolar structural modifier action in the process of structurization of solid hydrocarbons, detailed studies must be made of not only the final product (ceresin), but also narrow, uniform-composition fractions of the ceresin. To this end, the authors examined a petroleum from mixed West Siberian crudes. This product was cold-fractionated, taking 10/sup 0/C cuts. The fractionation was performed in the presence of the modifier n-C/sub 24/H/sub 50/ in the optimal quantity (0.05% by weight), which had been shown to be highly effective in deoiling. A dual solvent was used, MEK and toluene in a 45:55 weight ratio of the two components, and a 1:10 feed/solvent volume ratio. |
