PDF Coke Production US EPA

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".

Plasmochemical hydrogenation of coal is a new process of direct production of acetylene and alkenes in the gaseous phase, in contrast to traditional processes of coal hydrogenation (liquefaction). Propanebutane mixture (50% C 3 H 8 +50% C 4 H 10), 200 t −1, is used as a hydrogenating agent instead of hydrogen, 2000 t −1.

In this study, coal fly ash was functionalized, using a simple onestep process (loading with Al3+ and sulfonation), to yield a solid acid catalyst (S/AlCFA) with strong acid sites. The catalyst was then used to produce furfural from xylose in a biphasic system (H2O(NaCl)/tetrahydrofuran). The furfural yield reached 82% at 180 °C60 min with catalyst/xylose ratio of : (w/w).
