Pyrolysis is a thermal decomposition process that involves heating a substance in the absence of oxygen to produce various byproducts. In recent years, pyrolysis has been increasingly used to convert coal into useful chemicals and fuels, including heat for industrial processes. One promising application of pyrolysis is the direct heating of reactors using coal, which can reduce greenhouse gas emissions, lower operating costs, and increase overall efficiency.
To heat reactors directly from coal in pyrolysis, the process typically involves feeding coal into a reactor, where it is heated in the absence of oxygen to produce a variety of byproducts. These byproducts include gases such as methane, carbon monoxide, and hydrogen, as well as liquid and solid products such as tars and char.
The heat produced from the pyrolysis process can be directly transferred to the reactor, eliminating the need for separate heating sources and reducing overall energy consumption. This process has the potential to revolutionize the way reactors are heated, making them more efficient and cost-effective, while also reducing greenhouse gas emissions and contributing to a more sustainable future.
