Retrofitting hetrotrophically cultivated algae biomass as pyrolytic feedstock for biogas, bio-char and bio-oil production encompassing biorefinery

Energetic, economic and environmental assessment of the pyrolysis and combustion of microalgae and their oils

“…In this regard, Muñoz et al [22] proposed a preliminary biorefinery process for protein and biofuels recovery from microalgae based on pyrolysis. Furthermore, several studies have shown the benefits and sustainability of the integration of microalgae pyrolysis processes within the biorefinery framework due to their capacity of integration with transesterification and fermentation processes [23][24][25]. Together with pyrolysis, microalgae combustion seems another viable technology for microalgae valorization [11,26].…”

Pyrolysis of microalgal biomass in carbon dioxide environment

“…Therefore, biofuels from the inedible biomass (the second generation of biofuels) and from the aquatic biomass (the third generation of biofuels) were proposed as an alternative to the first generation of biofuels and the remarkable technical advances that have been achieved for the last 15 years (Do et al, 2015;Ma and Hanna, 1999;Park et al, 2015). In parallel, these technical advances have also brought force the concept of biorefinery to produce value added products and the substitution of petroleum-derived chemical products (Abdelaziz et al, 2015;Francavilla et al, 2015;Sarkar et al, 2015;Venkata Mohan et al, 2015). Unfortunately, in spite of the remarkable technical achievements, the concrete and optimum techniques for producing the second and the third generation of biofuels have yet to be fully implemented.…”

“…Dessa forma, o bio-óleo não pode ser usado diretamente como combustível, sendo necessária a remoção do oxigênio, ou seja, o melhoramento ("upgrading") desse bioproduto. Ainda assim, o bio-óleo possui várias vantagens como uma possível alternativa aos combustíveis fósseis, uma vez que é renovável e causa um impacto ambiental menor por não emitir enxofre, e por emitir quantidades inferiores de gases estufa, como o CO2, e até 50% menos NO 2 (SARKAR, et al, 2015).…”
