Abstract
Disclosed herein are processes, systems, and catalysts for improving pyrolysis technology. The disclosed processes and systems utilize a catalyst to increase pyrolysis gas (py-gas) and decrease bio-oil yields in pyrolysis reactions. The disclosed catalysts may include biochar derived from pyrolysis of industrial residuals, such as pyrolysis of wastewater biosolids (WB) and paper mill sludge (PMS). The disclosed catalysts also may include ash derived from incineration of wastewater biosolids ('biosolids incineration ash' (BIA)).
