Abstract. Development of renewable energy is essential to mitigating the fossil fuel shortage and climate change issues. Here, we propose to produce a new type of energy, biocoal, via a fast pyrolysis coupled with atmospheric distillation process. The high heating values of the asprepared biocoals from the representative biomass are within ...

A process flow diagram for a typical coal cleaning plant is presented in Figure In the initial preparation phase of coal cleaning, the raw coal is unloaded, stored, conveyed, crushed, and classified by screening into coarse and fine coal fractions. The size fractions are then conveyed to their respective cleaning processes.

There are two broad categories: (a) hard coal, which includes coking coal (used to produce steel) and other bituminous and anthracite coals used for steam and power generation; and (b) brown coal (sub bituminous and lignite), which is used mostly as onsite fuel. Coal has a wide range of moisture (240%), sulfur (%), and ash content (540%).

Bituminous: Even greater pressure results in the creation of bituminous, or "soft" coal. This is the type most commonly used for electric power generation in the It has a higher heating value than either lignite or subbituminous, but less than that of anthracite. Bituminous coal is mined chiefly in Appalachia and the Midwest.
