Situação patentária da pirólise de resíduos do coco para geração de bioenergia e bioprodutos

Abstract

Due to the urgent need to develop a sustainable production system, lignocellulosic biomass has emerged as a key element of this process. The use of this biomass for energy purposes, besides being an abundant and low-cost source, also contributes to adequate agricultural waste management such as from coconut (Cocos nucifera) production, which are slowly degraded and generally end up as pollutants in the environment. To promote this market, pyrolysis technology is used to convert the polymers from lignocellulose into solid, liquid and gaseous compounds of upgraded quality, being useful for the production of chemicals and fuels. To track and analyze in which context the combination of pyrolysis and coconut waste has been used to expand biorefineries, by means of technological prospecting in the World Intellectual Property Organization (WIPO) and National Institute of Industrial Property (INPI) databases it was analyzed the status of the patents on the subject. The results demonstrated that the leading destination for the pyrolysis of coconut waste has been for the formulation of biochar and biocarbon as intermediates or part of the process in a variety of industrial sectors, however, no patents were identified for obtaining the volatile pyrolysis products (biopyrolytic oil and gas).
