- Abstract
- The hydrocarbon composition of oils of asphaltene cracking products has been studied. The experiments were conducted in three different modes: without the use of additives (without water and catalysts - a "control experiment"), in a supercritical water environment without a catalyst and in a supercritical water environment with a catalyst based on iron oxides. Cracking was carried out in a reactor at a temperature of 450°C, the duration of the experiment was 60 minutes, the catalyst was obtained in situ from tris -acetylacetonate of iron(III). The individual hydrocarbon composition of the oils isolated from cracking products was determined using chromato-mass spectral analysis on the quadrupole system GCMS-QP5050A "Shimadzu". The hydrocarbon composition of asphaltene cracking products obtained in supercritical water differs in qualitative and quantitative characteristics from products obtained without water. When cracking asphaltenes in the water environment, the composition changes significantly compared to the "control experiment", an increase in the proportion of saturated hydrocarbons is noted. The cracking products obtained in water with the addition of a catalyst are also dominated by saturated hydrocarbons, while the content of phthalates, alkenes and sulfur-containing compounds significantly increases.
