Algal biomass to hydrogen: A circular approach for green sustainable processing with enhanced efficiency and minimal waste.

该项目研究了藻类生物质在可持续循环方法中的水热转化为富氢气体。一般情况下，培养的湿微藻（MA）在亚临界水中进行水热液化（HTL），产物分为气相、油相（生物原油）和水相（富有机物）。生物原油经催化加氢处理后可制成碳氢燃料，富有机物水相在超临界水条件下气化生成富h2气。本项目重点研究：(1)藻类生物质的生长，(2)超临界水气化（SCWG）将生长的生物质转化为氢气。该项目研究了获得最大量富氢气体所需的生物因素和工程参数。

The project investigates hydrothermal conversion of algal biomass to H2-rich gas in a sustainable circular approach. Generally, cultivated wet microalgae (MA) undergoes hydrothermal liquefaction (HTL) in subcritical water, and the products are separated into gases, oil phase (biocrude), and aqueous phase (organics-rich). The biocrude oil can be catalytically hydrotreated to hydrocarbon fuels, and the organics-rich aqueous phase undergoes gasification in supercritical water conditions to produce H2-rich gas. This project focuses on: (1) Growing of algal biomass, (2) conversion of grown biomass to hydrogen by supercritical water gasification (SCWG). The project investigates biological factors and engineering parameters required to obtain maximum amount of hydrogen-rich gas.
