Cogeneration process for production of energy and iron materials, including steel

Abstract From the Canadian patent

A process and arrangement are provided for the efficient generation of energy from coal while at the, same time providing for a relatively inexpensive step in processing of iron or steel, and the extraction of valuable materials such as oils from coal. An advantage to the process is that relatively low quality coals can be utilized, since the coal is pretreated before any burning operation. Generally, the process involves three interacting stages. In the First Stage a coal, liquefaction/pyrolysis procedure is utilized to drive off volatiles, and form a very low volatile char. The volatiles can be collected and utilized as a valuable oil product, such as for diesel fuel or the like. The char …
