The H-coal process is a demonstration of a new synfuel technology.
How could new synfuel technologies such as H-coal liquefaction affect environmental resources?
Researchers at Oak Ridge National Laboratory identified, evaluated, and ranked the potential ecological hazards posed by several synfuel technologies, including H-coal liquefaction. Research was based on (1) estimated quantities and compositions of aqueous, solid, and gaseous waste streams; (2) contaminant concentrations calculated for air, water, and soil; and (3) comparison of predicted exposure concentrations with toxicological and environmental benchmarks.
Aromatic amines, phenols, and cadmium were determined to be probable environmental concerns should full-scale development of H-coal technology take place. Polycyclic aromatic hydrocarbons (PAHs), mercury, arsenic, lead, nickel, copper, zinc, iron, beryllium, manganese, chromium, chlorine, NOx, SO2, and suspended particulates were categorized as possible concerns.
