Abstract

A family of silica-supported, magnetite nanoparticle catalysts was synthesised and investigated for continuous-flow acetic acid ketonisation as a model pyrolysis bio-oil upgrading reaction. The physico-chemical properties of FeO/SiO catalysts were characterised by using high-resolution transmission electron microscopy, X-ray absorption spectroscopy, X-ray photo-electron spectroscopy, diffuse reflectance infrared Fourier transform spectroscopy, thermogravimetric analysis and porosimetry. The acid site densities were inversely proportional to the FeO particle size, although the acid strength and Lewis character were size-invariant, and correlated with the specific activity for the vapour-phase acetic ketonisation to acetone. A constant activation energy (∼110 kJ mol), turnover frequency (∼13 h) and selectivity to acetone of 60 % were observed for ketonisation across the catalyst series, which implies that FeO is the principal active component of Red Mud waste.

摘要

合成了一系列二氧化硅负载的磁铁矿纳米颗粒催化剂，并将其用于连续流动的乙酸酮化反应，以此作为热解生物油升级反应的模型进行研究。通过高分辨率透射电子显微镜、X射线吸收光谱、X射线光电子能谱、漫反射红外傅里叶变换光谱、热重分析和孔隙率测定等手段对FeO/SiO催化剂的物理化学性质进行了表征。尽管酸强度和路易斯特性与FeO颗粒大小无关，但酸位点密度与FeO颗粒大小成反比，并且与气相乙酸酮化制丙酮的比活性相关。在整个催化剂系列中，酮化反应的活化能恒定（约110 kJ·mol）、周转频率（约13 h）以及对丙酮的选择性为60%，这表明FeO是赤泥废料的主要活性成分。
