Zeolite lignocellulosic biomass

Selective isomerization of glucose to fructose in aqueous medium Sn-p zeolite Fructose is easier to transform in suitable platform molecules than the abundant glucose. Hence, to find selective catalysts for this transformation is a critical key in the lignocellulosic biomass conversion [74]...

CFP [Catalytic Fast Pyrolysis] A process for converting lignocellulosic biomass into a mixture of aromatic hydrocarbons, notably / -xylene. It uses a fluidized bed at 500°C-1000°C and a modified ZSM-5 zeolite catalyst. Invented by G.W. Huber and colleagues at the University of Massachusetts-Amherst and licensed through Anellotech. The first plant is scheduled for completion in 2014. 

These processes involve a multistep transformation from the carbohydrate fraction to the value-added products which makes most of them far from commercialization. Hence, intensive efforts are stiU required to enable scale up of synthetic protocols developed on a lab-scale into industrial processes. Some of the current drawbacks might be overcome by the one-pot transformation of lignocellulose carbohydrates in value-added chemicals without isolation of the intermediate platform molecules (Delidovich et al., 2014). Moreover, nanoporous materials, such as acidic, basic or metallic catalysts (zeolites, mesoporous silicas, microporous/mesoporous carbons, resins, metal oxides, etc.), wUl play a crucial role in this biomass transformation (Wang and Xiao, 2015).
