Catalysis - Wikipedia

Catalysis - Wikipedia

Catalysis (/ k ə ˈ t l ə s ɪ s /) is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (/ ˈ k t əl ɪ s t /).Catalysts are not consumed in the reaction and remain unchanged after it. If the reaction is rapid and the catalyst recycles quickly, very small amounts of catalyst often suffice; mixing, surface area, and temperature are ...

Dec 01, 2018 By using a fluidized bed reactor, the optimized pyrolysis temperature was set at 450 C (e.g. 57% Bio-Oil yield). Thus, the Bio-Oil yield is not a linear relationship with temperature. The reason for this nonlinear bio-oil yield/temperature is the possible decomposition of some molecules into gases.
