Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Effects of separation methods on yield and quality of biocrude after thermochemical liquefaction of marine microalgae [PDF]

, 2018
Hydrothermal liquefaction (HTL) is a promising process for conversion of microalgae to biocrude that is upgradable to liquid transportation fuel. However, there is yet to be established standard separation method for product recovery.

Integrated co-HTL and two-stage extraction of fecal sludge and rice husk toward high-yield middle-to-heavy distillate-rich biocrude

Fuel Processing Technology
Hydrothermal liquefaction (HTL) is a promising technology for converting wet waste into biocrude; however, fecal sludge (FS)-derived biocrude is typically dominated by light fuel fractions, limiting its suitability for middle-distillate and heavy-fuel ...
