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 based on the Advanced System for Process Engineering (Aspen Plus) was applied to the CCHP system based on biomass pyrolysis. First, syngas was used as a fuel source for the CCHP system, which can be produced through a biomass pyrolysis experiment. In the experiment, the yields of the gas before and after the addition of a catalyst were compared. Second, syngas was passed to the reactor in Aspen Plus, which simulated the calorific values of the syngas produced by biomass pyrolysis under different conditions. Moreover, the simulated syngas heat values were applied to a TFRJ3K straw gas engine. Finally, the cost of the syngas for power generation, cooling, and heating was calculated. The power generation cost was 1.2 RMB/kW, the air conditioning refrigeration cost was 22.752 RMB/d, and the household heating cost was 20 RMB/d. [ABSTRACT FROM AUTHOR]
