Catalytic fast pyrolysis catalysts used

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. 

As mentioned previously zeohte catalysts have been used for the pyrolysis of plastics. A study by Ojha and Vinu converting polystyrene via catalytic fast pyrolysis using eight different zeohtes (ZSM-5, zeohte-P, and zeolite-Y families) identified that valuable chemicals, such as benzene, can be produced (Ojha and Vinu, 2015). Benzene yields depended on important zeohte properties such Si Al ratio, pore volume.
