Direct ammonia production via a combination of carbonization and thermochemical cycle from empty fruit bunch

摘要: Abstract Ammonia (NH3) has attracted much attention as both a fuel and an energy carrier due to its flexibility overall cleanliness. As hydrogen storage, it can be used for short long terms lower environmental impacts at the point of use·NH3 synthesis is commonly performed by reacting nitrogen via Haber-Bosch process. Due energy-intensive processes production, well high pressure required NH3 synthesis, alternative highly efficient system needed. An integrated that combines biomass pre-treatment (evaporation carbonization), combustion, thermochemical cycle power generation proposed in this work. By performing consisting reduction oxidation, process bypass steam reforming production. Additionally, under atmospheric condition absence catalyst. The based on enhanced integration involving exergy elevation recovery. Furthermore, effect conditions production efficiency performance different parameters are evaluated. result, utilization 100 t h−1 empty fruit bunch coproduce 8.95 t h−1 46.35 MW, respectively. Besides, developed achieve total net about 48%.
