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)).

Systems for pyrolysis and increased production of pyrolysis gas

Disclosed herein are methods for improving performance of an anaerobic digester system. The methods typically include adding a culture comprising hydrogenotrophic methanogens to the system, otherwise referred to as bioaugmentation.

Bioaugmentation of anaerobic digester systems

Disclosed are drying methods for preserving cultures of methanogens and dried cultures obtained by the disclosed drying methods. The dried cultures of methanogens may be reconstituted and utilized to bioaugment anaerobic digester systems.
