Composition of Diesel Fractions Produced by the Semicoking of Kukersite Shale in Different Equipment

详细

By chromatography and mass spectroscopy, industrial diesel fractions of tar obtained by the semicoking of Kukersite shale in a Kiviter gas generator and a Petroter-1 solid-fuel system are analyzed. The content of groups and types of compounds in the samples is compared. In the Petroter-1 fraction, the content of naphthenes (1.7%), dienes (2.6%), indenes (22.1%), ketones (7.3%), and furans (3%) is about twice that in the Kiviter fraction. In the Kiviter fraction, the content of paraffins (17.4%), olefins (19%), alkylbenzenes (23%), and naphthalenes (16.1%) is higher by a factor of about 1.3. The presence of oxygen-bearing compounds in the flue oil permits satisfactory solution of the tars and asphaltenes of the petroleum residues and decrease in their pour point. In other words, the performance of petroleum fuel-oil is significantly improved.
