Abstract

The problem of utilisation of heavy oil by-products during oil refining is associated with high content of tarry asphaltene substances, coke, heavy metals and catalyst dust. A promising way to obtain commercial products from cube residues is low-temperature plasma chemical pyrolysis in liquid phase (NTP-plasma). The present work investigates the process characteristics of plasma-chemical pyrolysis of catalytic cracking residues (CCR) at current source voltages of 300- 700 V in order to optimise product composition and energy consumption. The gaseous NTP products of CCR pyrolysis contain (%mol): hydrogen (63.0-65.5), acetylene (21.8-23.6), methane (6.3-7.7), ethylene (2.7-3.4) and C3 - C6 hydrocarbons (1.9-3.7). Solid pyrolysis products are conglomerates of "sticky" particles of rounded shape in the size range from units to tens of microns. The maximum conversion of CCR pyrolysis was 78.9 % wt% at a minimum energy input of 3.3 kWh/kg at 500V.
