Resumo
The potential of microalgae Spirulina platensis to the production of nitrogenous compounds in liquid fraction via
slow pyrolysis was evaluated. Aiming to identify the best condition which maximized liquid yield, the effects of
operational conditions mass load, temperature, and heating rate were evaluated using Experimental Design and
Response Surface Methodology techniques and optimized with Differential Evolution methodology. The composition of liquid fraction was analyzed by GC–MS and the effect of the same operational conditions in nitrogenous compounds formation was analyzed. The separation of nitrogenous compounds was evaluated by
extraction and adsorption techniques. The results indicated that the heating rate significantly impacted both the
liquid yield and the formation of the nitrogenous compounds. At optimal conditions, a maximum liquid yield of
64.59% was obtained. The extraction and adsorption processes showed to be promising routes for the purification of nitrogenous compounds, however, extraction was more selective to separate them.
