Dec 26, 2017 · Abstract: A process for producing mesophase pitch from hightemperature coal tar comprises: removing salts and quinoline insoluble fraction from a hightemperature coal tar to obtain a decant oil; using the decant oil as a hydrogenation feedstock, or predistilling the decant oil to obtain a residue with a boiling point higher than 230 and formulating the residue into a hydrogenation feedstock ...
Coke is an essential material for the global steel industry, and the coal tar produced in its manufacturing process is also used as a raw material for many types of products. We procure coal from a number of countries and blend it with 60 to 70 types of raw materials to produce coke of various quality grades.
Aug 30, 2020 · Abstract The refining of coal tar by hydrogenation is considered. In this process, nanoheterogeneous Nibased alysts may expediently be produced in situ from precursors in the reaction medium. The yield of needle coke in complete coal processing with recirculation of the residue at the coking stage is found to be 50–55%. That is times the industrial yield in the coking of pitch.
To complete pilot plant demonstration of advanced coal refining technologies and novel reactors, pyrooil upgrading technologies in five years. Coalderived Materials Coal derived performance materials are technology driven, value added, coal originated and/or converted materials that are developed for clean and low carbon appliions.
Pyrolysis of Petroleum or Coal Tar Pitch. Raw pitch, a high molecular weight byproduct formed during petroleum or coal refining operations, is composed of a rather broad mixture of hundreds of thousands of organic species with an average molecular weight of several hundred.
From the 1880s to the early 1960s, operations at the St. Louis River/Interlake/Duluth Tar site included coal tar refining, tar product manufacturing, coking and .

Coal tar refining is a key component of a value chain, beginning with coal tars produced as a byproduct by integrated steel mills. If not refined, this byproduct would need to be disposed of as a hazardous waste, at high costs. Refining of coal tars produces key raw materials for downstream industries and functional users, including Canada ...
Coal tar creosote contains light coal creosote and heavy coal creosote. Coal tar creosote is often applied in carbon black and wood preservative and others, of which carbon black industry occupies the largest share. The production of Coal Tar Creosote decreased from K MT in 2011 to K MT in 2015, with a CARG of more than %.
