Abstract (Summary)

In the last decade, coal-driven power generation has given way to cleaner energy production. In places abundant with the natural resource, alternative applications for coal are crucial to local economies. Hydropyrolysis is able to fulfill this requirement by extracting profitable coal volatiles under an atmosphere of hot, high-pressure hydrogen. Recent developments in numerical models for coal devolatilization, tar hydrogenation, hydrogasification, and chemical kinetics allow for novel studies to ensure the scalability of experimental results. Research efforts have successfully developed several zero-dimensional models and a kinetics model with applicability to computational fluid dynamics (CFD). Furthermore, advancements in CFD permit the simulation of hydropyrolysis facilities at economically viable flow rates allowing for preliminary design considerations to be investigated. Coupling these models together will allow for the optimization, and hopefully construction, of a hydropyrolysisplant.
