Catalytic fast pyrolysis (CFP) is one of most promising technologies for aromatic production in a single‐step process. In recent years, considerable efforts have been made on the CFP of biomass for aromatic productions. However, the successful commercialization of CFP has hindered by several technical barriers, such as the rational design of continuous reactor and the development of high efficient and stable zeolite catalysts. Here, we attempt to summarize the advances in CFP of biomass from four aspects: (1) reaction chemistry, (2) reactor and operating conditions for CFP, (3) catalysts for CFP, and (4) new processes for CFP. It is expected that this review could provide some guidance for solving the technical barriers aforementioned.
