As enlergy demand continues to grow, low-cost and efficient production of renewable biofuels becomes essential to drop carbon emissions in the transportation sector. Catalytic fast pyrolysis is a process that uses a catalyst, such as zeolites, to decompose biomass in a liquid product that can be later upgrade into bio-gasoline or bio-diesel. However, zeolites tend to deactivate very rapidly under reaction conditions. Understanding the deactivation mechanisms of zeolites during fast pyrolysis will enable de development of more efficient catalyst to meet future demand of biofuels. Zhang et al. 2014, studied the coke deposition on zeolite catalysts during the conversion of furan (a main intermediate of biomass fast pyrolysis) using a fixed-bed micro catalytic reactor. From the reported data on Furan conversion shown below: (a) Develop an expression to represent the deactivation rate of this catalyst assuming a first order reaction and first order deactivation (b) Discuss if the assumptions made for the reaction and deactivations rates are helpful to describe this system (c) Propose the main possible deactivation mechanism for this process and explain your reasoning
