Production of brown algae pyrolysis oils for liquid biofuels depending on the chemical pretreatment methods

Pyrolysis Behaviours of Microalgae Nannochloropsis gaditana

“…In the slow pyrolysis of Saccharina japonica, a greater number of liquid products were observed with increasing pyrolysis temperature [30]. After the fixed-bed pyrolysis of S. japonica (470 °C), 37.9% of the liquid products were obtained [31]. The amount of liquid products obtained from the slow pyrolysis of S. japonica was similar to its pyrolysis at 500 °C in our study.…”

Macroalgae-Derived Biofuel: A Review of Methods of Energy Extraction from Seaweed Biomass

“…In another study, pre-treatment of Saccharina japonica with sulphuric acid was undertaken in order to remove inorganic contaminants that may have an influence on the pyrolysis process itself. Implementing this strategy was found to increase the fatty acid composition of the resulting bio-oil, but inhibited the formation of large char chunks that were found to hinder the continuous pyrolysis of the untreated macroalgae in a fluidise bed [72].…”

Cascade approach of red macroalgae Gracilaria gracilis sustainable valorization by extraction of phycobiliproteins and pyrolysis of residue

“…It was claimed that bio-oil production for various uses is feasible after appropriate pretreatment of the feedstock (Bae et al, 2011). Various pretreatment methods with promising results have been introduced in order to remove the ash content of macroalgae (Ross et al, 2009;Bae et al, 2011;Choi et al, 2014;Ferrera-Lorenzo et al, 2014). As a consequence of pretreatment, losses also of organic compounds might occur.…”
