Autohydrolysis and alkaline pretreatment effect on Chlorella vulgaris and Scenedesmus sp. methane production
Mahdy, Ahmed; Mendez, Lara; Ballesteros, Mercedes; … - In: Energy 78 (2014) C, pp. 48-52
alkaline (0.5, 2 and 5% w/w NaOH dosages)) on Chlorella vulgaris and Scenedesmus sp. The autohydrolysis resulted in 16 and 6 …% chemical oxygen demand (COD) solubilisation for Chlorella and Scenedesmus, respectively. During thermoalkaline pretreatment …, COD in soluble phase (CODsol) was increased up to 19% for Chlorella and 17% for Scenedesmus sp. The highest carbohydrates …

Integration of energy-efficient drying in microalgae utilization based on enhanced process integration
Aziz, Muhammad; Oda, Takuya; Kashiwagi, Takao - In: Energy 70 (2014) C, pp. 307-316
We propose an integration of drying with gasification and combined cycle-based power generation for microalgae. This system is based on enhanced process integration, which includes two core technologies: exergy recovery and process integration. Exergy recovery is achieved by exergy elevation and...

Life cycle costs for the optimized production of hydrogen and biogas from microalgae
Meyer, Markus A.; Weiss, Annika - In: Energy 78 (2014) C, pp. 84-93
Despite the known advantages of microalgae compared with other biomass providers or fossil fuels, microalgae are predominately produced for high-value products. Economic constraints might limit the commercial energetic use of microalgae. Therefore, we identify the LCCs (life cycle costs) and...
