Hydrothermal liquefaction (htl) is a thermal depolymerization process used to convert wet biomass into crude-like oil -sometimes referred to as bio-oil or biocrude- under moderate temperature and high pressure the crude-like oil (or bio-oil) has high energy density with a lower heating value of 338-369 mj/kg and 5-20 wt% oxygen and renewable. Nrel is a national laboratory of the us department of energy, office of energy efficiency & renewable energy, operated by the alliance for sustainable energy, llc.
A new generation of the htl process can convert all kinds of biomasses to crude bio-oil, which is sufficiently similar to fossil crude oil that a simple thermal upgrade and existing refinery technology can be employed to subsequently obtain all the liquid fuels we know today what is more, the htl process only consumes approximately 10-15. Thermal depolymerization (tdp) such as direct hydrothermal liquefaction these are distinct from processes using dry materials to depolymerize.
Hydrothermal liquefaction of three types of algae and its product characterization. Of all the pathways to drop-in algae biofuels, few have remained as promising as hydrothermal algae liquefaction it may not roll off the tongue, but it might be the most important technology to come along in years.
