The concern of the population and especially of the scientific community with respect to the eminent lack of fossil fuels and their environmental impacts are notorious. The objective of this study was to enable the utilization of residual biomass from coculture using pyrolysis thermochemical technology for the production of bio-oil. The experiment was carried out in the analysis laboratory of Qualitex Engenharia and the LASSOP - Laboratory of Separation and Process Optimization Systems, Graduate Program in Chemical Engineering, Federal University of Alagoas - UFAL. The parameters of pH, solids, ash, moisture, apparent density, higher calorific value, carbon, nitrogen, hydrogen, sulfur, calcium, manganese and zinc were evaluated by physical-chemical tests. In the bio-oil, the pyrolysis product was analyzed parameters moisture, density, oxygen, carbon, hydrogen, pH, PCS, solids and viscosity. The physicochemical analysis of the biomass residues of the coconut biomass, the thermochemical conversion of the coculture biomass through the tubular pyrolysis reactor and the analysis of the characteristics of the conversion products, such as bio-oil, biochar and biogas, were carried out. With the pyrolysis carried out with the coconut shell, it was possible to take advantage of 100% of the biomass, with the conversion into bio-oil, bio-bio and biogas, achieving excellent results, besides contributing to the reduction in the emission of atmospheric pollutants. The results presented energetic gain in relation to the raw material of up to 1.40 MJ kg-1 in the mesocarp fraction at 400 ºC and up to 4.84 MJ kg-1 in the endocarp fraction at 600 ºC. The average value of 2.39 MJ kg-1 equivalent to 13% of energetic gain in relation to coconut biomass in natura.
