A series of SO42-/ZrO2-TiO2 catalysts with different Zr-Ti molar ratio were prepared by precipitation and impregnation method,and characterized by NH3-TPD,XRD and XPS techniques.
Cellulose is the most abundant biopolymer on earth,and it holds great potential as an alternative source of valuable chemicals and fuels,especially since the gradual depletion of fossil fuels is now b
Solid acid catalyst and extremely low sulfuric acid catalyst were used to consist mixed-acid systems in this study.Direct synthesis of ethyl levulinate from glucose catalyzed by mixed-acid systems was
Biomass fixed bed gasification technology features such merits as a stable operation and capability to serve as a clean energy source,however,there exist some problems,namely,a low gasification effici
The mechanism for the pyrolysis of phenethyl phenyl ether(PPE)—a representative model of a linkage found in lignin—has been investigated over the years,and the existence of both free radical and conce
In Hong Kong,there are around 3,600 tonnes of food waste generated,which is made up of 40%of Municipal Solid Waste(MSW).Fifty-two percent(52%)of the MSW generated is dumped into landfills.It is estima
Lipase,which would be produced by Yarrowia lipolytica yeast,plays important roles in bio-diesel and relevant esterification and transesterification catalytic process.The activity of lipase is decisive
The long-term economic viability of the North America(particularly Canada)forestry sector has been threatened in recent years due to many reasons such as high energy and fibre costs,and the falling de
Forest Residue is the most affordable feedstock for biofuel production based on a recent US National Research Council Report.However,forest residue is highly recalcitrant for enzymatic saccharificatio
