The present disclosure relates to a method of producing metallurgical coke from a combination of non-coking and non-metallic carbon-based microwave susceptor. The method is energy efficient, economical, and environmentally friendly. The present disclosure also relates to metallurgical coke having improved coke quality, such as improved coke strength after reaction.

Method for producing metallurgical coke and the metallurigical coke thereof

The present relates to organic compound(s) [i e compound of formula I or compound of formula IA] and/or a composition comprising said organic compound(s) useful for utilization of non-coking coal in a blend comprising coking coal without deterioration of properties of coking coal, wherein said organic compound(s) is capable of releasing hydrogen in the plastic region of coal. The present disclosure provides a simple, economical, non-toxic and an efficient method for the preparation of said organic polymer and a method for utilization of non-coking coal in blend comprising coking coal without deterioration of properties of coke.

Compounds, compositions and methods for utilization of non-coking coal

The present disclosure relates to a method for producing metallurgical coke from non-coking coal. The method comprising, densifying, the non-coking coal to form pellets. The densified pellets will be placed in a microwave oven within plurality of bricks and are subjected for pyrolysis. For carrying our pyrolysis, the pellets are carried out by heating, the pellets in the microwave oven at a predetermined temperature under an inert atmosphere at atmospheric pressure, and then the pellets are cooled in the microwave oven under the inert atmosphere. This process coverts non-coking coal to the metallurgical coke in a quicker time, and without use of any susceptors.

Method for producing metallurgical coke from non-coking coal

A beneficiation process to produce low ash clean coal from high ash coals, including: preparing a coal slurry from fine coal and water and discharging it to a first reactor; preparing an alkali solution and discharging it to a first reactor; carrying-out a leaching reaction inside the first reactor; transferring the reaction mixture to a second reactor for filtration and washing to produce a filter cake; preparing a diluted acid solution and delivering it to a second reactor; preparing a diluted alkali solution and delivering it to a second reactor; feeding a coal slurry prepared from the filter cake into the second reactor for washing and transferring to a second filtration unit; transferring the product after filtration to a third reactor; carrying-out different leaching reaction sequences in the first, second, and third reactors; and transferring to a fifth tank the treated coal filter cake for drying.
