SUMMARY:Seminar Speaker/Professor Charles Xu
CLASS:PUBLIC
DESCRIPTION:Biomass plays a key role in capturing and storing solar energy 
 on\nEarth. It is estimated that up to 8\,500 exjoules (×10¹⁸ joules) o
 f\nsolar energy are captured and stored globally each year through\nbiomas
 s\, which is about 10-15 times the current global energy\nconsumption (580
  exajoules). This presentation provides an overview of\nthe availability o
 f biomass and organic solid waste resources\nglobally\, as well as in Chin
 ese mainland and Hong Kong\, and introduces\nhydrothermal technologies and
  their applications in the transformation\nof biomass and organic solid wa
 ste. During these transformations\,\nwater is used as a reaction medium\, 
 solvent\, reactant\, or catalyst.\nHydrothermal technology is especially s
 uitable for the resource\nutilization of high-moisture biomass and biowast
 e (such as food waste\,\nsewage sludge\, manure slurry\, microalgae\, etc.
 )\, as it eliminates the\ncostly dehydration/drying process (which is esse
 ntial for other\nthermochemical processes like combustion\, pyrolysis\, an
 d\ngasification). This presentation summarizes Professor Xu's team's past\
 nresearch achievements in various hydrothermal technology development\,\ni
 ncluding methanol aqueous phase reforming (APR) for hydrogen\nproduction\,
  biomass hydrothermal carbonization (HTC) to produce\nwater-charcoal\, hyd
 rothermal liquefaction of biomass waste (HTL) to\nproduce biocrude oil\, a
 nd supercritical water gasification (SCWG) of\naqueous biomass (sugars) to
  produce green hydrogen. Professor Xu will\nalso share his experience in s
 caling HTL technology to 6 kg/h and 100\nkg/h\, as well as ongoing commerc
 ialization efforts\, including building\npilot units with a daily throughp
 ut of 10 tons and demonstration units\nwith a daily throughput of 100 tons
 .
