Technology roadmap: as tendências da utilização do bio-óleo em processos catalíticos de refino

Abstract

The need to decarbonize the energy matrix based on fossil fuels has led different segments to seek alternatives through the use of biofuels. This study proposes, with the help of the prioritization technique called Roadmap, to analyze the trend regarding the use of bio-oil in different operations carried out in refineries, for the co-processing of renewables in their units. The Roadmap methodology consists of a temporal evaluation, enabling the identification of associations between different institutions (companies and universities or research centers). The study considered a time interval of 11 years. The taxonomy identified in the reading of all the material was used for the analysis, allowing the evaluation of the state of the art in terms of types of catalysts, application of the hydrodeoxygenation (HDO) process of bio-oil, types of co-processing, whether it occurred in fluid catalytic cracking (FCC), in the hydroprocessing stage (HDT) or catalytic hydrocracking (HCC). Based on the technique, maps will be presented: of the short-term situation, referring to the analysis of approved patents and what has already been accomplished; with the medium-term trend, based on patent applications; of the long-term, considering the information extracted from articles; and a final map of the current stage covering both articles and patents of the period, available on several platforms (Scopus, Science Direct, among others). The Technology Roadmap constructed allowed mapping the co-processing of bio-oil in fluidized bed catalytic cracking (FCC) units as being the most explored, economically viable technology with opportunities for development, made it possible to identify FCC catalysts, containing zeolites in their formulation, as the most promising, concentrating the focus of current research routes on the need to avoid deactivation of catalysts during the process.
