Selection of Raw Materials for High-Quality Needle Coke

The aim of the study is to study the possibility of obtaining anisotropic needle coke, using various types of heavy pyrolysis resin, decantoil and a mixture of decantoil and heavy pyrolysis resin as raw materials in laboratory conditions. The coking process was carried out at a temperature of 470°C in a laboratory installation of periodic action in static conditions. A study of the influence of the composition of raw materials on such important indicators of coke as the sulfur content in coke and the assessment of the microstructure according to a special ball technique The production of cokes with a low scoring is due to the fact that under static conditions there is no directed movement of the flow of the raw material mixture, as is realized in industrial plants for delayed coking.
