| Summary: | Title screen Plasma technologies enable rapid thermal processing and cracking of hydrocarbons. This study investigates the cracking of water/oil systems (rapeseed and tall oils) using a plasma jet to induce explosive boiling for biofuel synthesis. A plasma chemical reactor with an adjustable operating current (60–160 A) was used to determine the critical conditions and outcomes of explosive boiling in distinct layers and emulsions (water fractions up to 10 vol%). The influence of plasma parameters, gaseous medium, and system configuration on cracking time and gaseous products (CO2, CO, NOx, SO2, CH4, C3H8) was established. Key findings reveal that adding 10 vol% water reduces cracking time by up to 30%, and using emulsions over layered systems intensifies the process by up to 25%. Furthermore, water content significantly alters gas selectivity, enhancing hydrogen and carbon monoxide yields. A physical model of the cracking process was developed, accounting for thermal conditions and chemical transformations. Finally, a multi-criteria analysis was employed to identify optimal cracking conditions, revealing that the most efficient system is highly dependent on the prioritized outcome (energy efficiency vs. environmental impact). The results demonstrate that explosive boiling under plasma exposure is a viable method for intensifying the conversion of oil-based feedstocks into valuable gases Текстовый файл AM_Agreement |
