A novel process designed for producing methanol from coke oven gas (COG) integrated with CO 2 recycle is proposed. In the new system, oxygen replacing air is blown to combustor for assisting combustion of COG and unreacted syngas from methanol synthesis process. The combustion process provides to the heat required in the coking rest COG reacts with the recycled CO 2 separated from ...

Coke is a grey, hard, and porous coalbased 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 a concern.

Coking coal is an important raw material for coke production. In this study, in an inert atmosphere, two Chinese coking coal samples were, respectively, heated gradually to 1200 °C to release volatile and form char and coke in succession, then cooled naturally to close room temperature to age the coke. The whole heating and cooling process on carbonization were monitored in situ by ...

SiC is one of the main intermediate compounds formed during the industrial production of silicon (Si). In the Si process, SiC is produced when carbon added to the raw materials reacts with the silicon monoxide gas (SiO(g)) formed in the furnace. Carbon materials used are either biomassbased (charcoal and wood chips) or based on fossil sources (coal, coke, petroleum coke). The most common ...

The key difference between coal and coke is that Coal is a naturally occurring fossil fuel. Coke, on the other hand, is derived from heating coal. In other words, Coal originates naturally from the fossilization of organic matter over millions of years. In contrast, Coke is derived from coal through a process called coking, involving high ...
