Low Temperature Hydrothermal Pre-Treatment of Algae to Reduce Nitrogen Heteroatoms and Generate Nutrient Recycle Streams
October 27th, 2015 | No Comments | Posted in Algae-Cultivation, Research, United States, University Research
Scientists from USA conducted an experiment to reduce nitrogen heteroatoms and generate nutrient recycle streams in algae. A two-stage hydrothermal liquefaction process was used for this purpose. A low temperature liquefaction 
treatment hydrolysed proteins and separated nitrogen to the aqueous phase which was later removed for analysing nutrient and toxic concentrations.
Results showed that the low temperature pre-treatment was most effective at higher temperatures removing 45% of nitrogen present in algae solids. The aqueous co-product stream was analysed for nutrient availability which indicated potential for recycle and algae cultivation.
