Surplus biomass is one of the most attractive feedstock as it is renewable and sustainable, which can be used for the production of biofuels/chemicals. However, biomass is contents higher oxygen, which is hindered in application as a fuel. For improving the bio-oil quality, a process parameter such as catalyst needs to be endured for production of fuel-grade bio-oil. Catalytic fast pyrolysis of rice straw (RS) and wheat straw (WS) were performed using basic (MgO and CaO) and acidic (ZSM-5 and Y-zeolite) catalyst at different reaction temperature. It was found the different compositions of feeds reacted differently with presence of different catalysts. Pyrolysis products were grouped as carbonyls, phenolics heterocyclic and aromatic hydrocarbons. Carbonyls were observed as major compounds under the non-catalytic condition. Higher amount of carbonyls (62.91%) was obtained at 400 °C in case RS, while in case of WS lower amount was found (57.72%) without use of catalysts. However, catalysts such as basic metal oxide are encouraged to formation of phenolics and ketones compound, while acidic catalysts were encouraged to formation of aromatic hydrocarbons. Moreover, higher amount of aromatic hydrocarbon (52.9%) was found with RS using Y-zeolite, whereas higher amount of phenolics (48.5%) was obtained with WS using CaO catalysts.

剩余生物质是最具吸引力的原料之一，因为它是可再生和可持续的，可用于生产生物燃料/化学品。然而，生物质的氧含量较高，这在作为燃料的应用中受到了阻碍。为了提高生物油的质量，生产燃料级生物油需要承受催化剂等工艺参数。使用碱性（MgO 和 CaO）和酸性（ZSM-5 和 Y-沸石）催化剂在不同反应温度下对稻草 (RS) 和小麦秸 (WS) 进行催化快速热解。发现不同组成的进料在不同催化剂的存在下反应不同。裂解产物分为羰基、酚类杂环和芳烃。在非催化条件下观察到羰基作为主要化合物。在 RS 的情况下，在 400°C 下获得了较高量的羰基化合物 (62.91%)，而在 WS 的情况下，在不使用催化剂的情况下发现了较低的量 (57.72%)。然而，促进碱性金属氧化物等催化剂形成酚类和酮类化合物，而促进酸性催化剂形成芳烃。此外，使用 Y 型沸石的 RS 发现更高量的芳烃（52.9%），而使用 CaO 催化剂的 WS 获得更高量的酚类（48.5%）。
