(768e) A Process Model for Converting Low-Lipid Microalgae into Biocrude Oil Via Hydrothermal Liquefaction
Investigating different configurations of the feedstock pretreatment, hydrothermal liquefaction (HTL) conditions, upgrading of biocrude oil and recycle of nutrients will help develop a sustainable and robust system for the highest net energy production and the lowest greenhouse gas emission. The present work intends to use process simulation tools to analyze the feasibility of HTL process that employs wild-harvested microalgae and cyanobacteria to produce biocrude oil and recycle the nutrients. A detailed mass balance, energy balance, techno-economic analysis will be investigated from feedstock to the final products. The simulation will be carried out by using Aspen Plus software, based on experimental results from model compounds and whole algae via HTL process.
