It is proposed to use plasma chemical method for joint processing of fuel oil and lignite at the unit with productivity of 1000 kg/h. It is shown that at shallow plasma-chemical treatment of the mixture there is a significant cracking of the organic part. The yield of liquid hydrocarbons is ~77 % of the theoretical one. By the method of chromato-mass-spectrometry the group composition of the obtained liquid product, boiling up to 400 °С, which contains, %: 54 - linear paraffins (including 37 solid paraffins); 15 - isoparaffins; 4 - cycloparaffins; 4 - olefins and 23 - aromatic compounds. Total power consumption for plasma-chemical processing of 1 ton of feedstock is ~31 kW (including 6 kW for operation of the plasma-chemical reactor), not counting the cost of separation of liquid fractions of hydrocarbons and semi-coke from the processed product.
It is proposed to use the plasma-chemical method for processing fuel oil in an installation with a capacity of 1000 kg/h. It has been shown that with shallow plasma-chemical treatment, signifi cant cracking of the high-boiling part of the fuel oil occurs. When processing fuel oil using the plasma-chemical method followed by distillation of liquid products, the following is obtained: 6,7 % of gas; 48,0 % of residue; 11,2 % of solvent (n.k.–250 °C) and 34,1 % of heating oil (251–360 °C). Th e following percentages were obtained from heating oil by distillation: 0,3 – gas; 30,2 – low-viscosity marine fuel SMT (251–330 °C) and 3,6 – fuel oil F-5 (331–360 °C). Th e resulting residue with a penetration of 150 dmm and a ring and ball softening temperature (S&T) of 73 °C can be used as a component of road bitumen and delayed coking raw materials. Th e total energy consumption for plasma-chemical processing of 1000 kg of fuel oil is about 30–40 kW (including the operation of a 6–8 kW plasma-chemical reactor).
