Differentiation of coking & non-coking coals

2020-11-8  of coal which is used for determining of coking coal is the petrographic analysis & reflectance. The coking coal should have a minimum of 60% virtrain (active constituents) and maximum of 40% Inertinite (non—reactive constituent). For finding out the physical strength of the coke, reflectance studies on coking coal is also done.

2 天前  Petroleum refining Petroleum refining Visbreaking, thermal cracking, and coking: Since World War II the demand for light products (e.g., gasoline, jet, and diesel fuels) has grown, while the requirement for heavy industrial fuel oils has declined. Furthermore, many of the new sources of crude petroleum (California, Alaska, Venezuela, and Mexico) have yielded heavier crude oils with higher

Coke Strength an overview ScienceDirect Topics

Tiwari et al. (2013) proposed a coefficient named composite coking potential of coal/coal blend calculated from coal properties (chemical, rheological, petrographic), which in turn is correlated with the coking properties. Again, such a prediction model is only valid for the range of coals investigated in the study and the carbonizing conditions.

Coke (fuel) Wikipedia

2021-2-25  Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is

Coking » Delayed Coker Unit (DCU)

A delayed coker is a type of coker whose process consists of heating the residual oil feed to its thermal cracking temperature in a multi parallel pass furnace. This cracks the long chain heavy carbon and hydrogen molecules of the residual oil into coker gas oil and pet coke. Cracking begins in the furnace, continues in the transfer line, and finishes in the coke drum. (wikipedia definition
