摘要：Purpose: Thermal and Physicochemical evaluation of açaí seeds for its use in thermochemical conversion processes for clean energy generation. Methodology: Experimental and qualitative research, using analyzes such as: Thermal analysis (TG/DTG and DTA curves) and Calorimetry, Ultimate and Proximate analyzes, Scanning Electron Microscopy, Energy Dispersive Spectroscopy, X-Ray Diffraction, Fourier Transform Infrared Spectroscopy and Optical Emission Spectroscopy - Inductively Coupled Plasma. Findings: It was noted that the açaí seeds presented carbon, hydrogen, and oxygen contents as majority elements and a Higher Heating Value (HHV) of 19.8 MJ kg-1. Nitrogen and lead elements were found as trace elements. However, highly polluting elements, e.g., sulfur, cadmium and arsenic were not detected in the samples. Originality: The utilization of açaí seeds by means of thermoconversion processes for bioenergetic purposes can be an attractive socioenvironmental, reducing disposal in inappropriate places, adding considerable value to waste and still protecting the environment.
