“Behavior of Multiwalled Carbon Nanotube Catalyst Under Supercritical Water Condition in a Continuous Flow Reactor”

Carbon catalysts have been attracting attention from many researchers for different approaches due to its an important role in biomass. Multiwa11ed carbon nanotube (MWCNT) is a possible biomass catalyst. In this study MWCNT was used as a feedstock and gasified under supercritical water using a laboratory scale continuous flow reactor. The behavior of MWCNT including carbon gasification efficiency, gas composition, total organic carbon in the liquid product and solids products are discussed.

“Behavior of Glycine in Supercritical Water Gasification in Less than 5 s”

Supercritical water gasification (SCWG) is attracting attention because it can convert biomass quickly and almost completely. When nitrogen containing feedstock is to be gasified, behavior of nitrogen under hydrothermal conditions is important. There are some studies about amino acid decomposition in subcritical condition. It is also known that ionic reactions mainly take Place under subcritical condition. As for supercritical conditions, amino acid is known to decompose rapidly, and its decomposition rate has not been determined due to its short reaction time. In this study, We conducted SCWG of glycine in less than 5 s. The experiment was conducted using a tubular flow reactor at 25 MPa and glycine was empIoyed as feedstock. Order of the decomposition rate was determined.

“Precipitate Recovery of Calcium Phosphate from Hydrothermally Treated Adenosine Triphosphate’’

Our group has isolated more than 70 1ectins, Sugar-binding proteins, from algae and elucidated that algal lectins show novelties of molecular structures and carbohydrate recognition mode. The unique binding properties of alga lectins are applicable as diagnostic tooIs and phamaceuticals: Several algal lectins specifically recognize glycan markers of cancers and show strong anti-viral activities against HⅣ and influenza viruses, Which possess the characteristic glycans on their envelope. In this talk, structural and functional features of

algal lectins are summarized and highlighted towards more advanced usage of them.
