Ni-based catalysts supported on olivine were synthesized for cracking the biomass and producing the syngas. Syngas is used directly as fuel source for the cooling, heating, and power (CCHP) system, which can be produced through biomass pyrolysis process. Integrating combined CCHP systems with biomass pyrolysis results in a sustainable distributed energy system that effectively utilizes biomass resources and improves energy efficiency. To achieve a higher energy efficiency and more cost-effective operation, a simplified cost analysis method base...
