Thermogravimetric analysis of microalgae combustion under different oxygen supply concentrations

Arthrospira (Spirulina) platensis cultivation in tubular photobioreactor: Use of no-cost CO2 from ethanol fermentation

“…Particularly, the state of São Paulo is the largest producer of ethanol in Brazil and its production achieved, in 2008/2009, about 17 billion liters [16], which corresponds to about 13 billion kg of CO 2 . This huge amount of CO 2 could be profitably used to produce about 7 billion kg of biomass, which may be used to obtain energy through combustion [19], gasification [20] or processes involving anaerobic fermentation for the production of energetic gases such as biohydrogen and biomethane [21].…”

Characterization of Microalgae for Lipid Extraction

“…Weight loss may arise from the evaporation of residual moisture or solvent or from the decomposition of organic matter at higher temperatures. If oxygen or air is used as the carrier gas then oxidation of organic matter also contributes to the weight loss (Tang et al, 2011;Chen et al, 2011). Although TGA is useful in determining volatile matter its accuracy remains approximate because TGA cannot precisely distinguish the components within a mixture.…”

Experiments and Kinetic Modeling for the Oxidative Decomposition of Herbaceous and Wooden Residues

“…and wooden (a plant having hard lignified tissues or woody parts especially stems, such as pine, tung, aspen, cypress, etc.) residue owing to its economical convenience, high production, and high adaptability (Chen et al 2011). Wang et al (2013) investigated the combustion characteristics of seaweed using a small fluid bed device and studied the release process of NOx, SO2, and CO.…”
