Plasma-Chemical Processing of Fuel Oil with Lignite

Abstract

A plasma-chemical method is used to process a mixture of fuel oil and lignite in a system of productivity 1000 kg/h. Mild plasma-chemical processing is associated with considerable cracking of the organic component. Liquid hydrocarbons are produced in ~77% of the theoretical yield. By chromatography and mass spectrometry, the group composition of the liquid product is established. This product boils at temperatures up to 400°C and contains 54% linear paraffins (including 37% solid paraffins), 15% isoparaffins, 4% cyclic paraffins, 4% olefins, and 23% aromatic compounds. The total power consumption in processing 1 t of raw material is ~31 kW (including 6 kW in the operation of the plasma-chemical reactor), disregarding the expenditures in extracting the liquid hydrocarbon fractions and the semicoke from the product.
