This work examines the hydrodeoxygenation (HDO) activity of non-edible oils using a high surface area catalyst. The HDO activity was thoroughly examined and contrasted using the high surface area catalyst Ni/Pt-ZSM-5 as well as other supports like MCM-48 and H-beta. Ni/Pt bimetals supported on mesoporous ZSM-5 were created reverse order impregnation to facilitate HDO of non-edible oils. Techniques such as XRD, FT-IR, BET, HR-TEM, HR-SEM, TPD, and TGA were used to characterize the produced catalysts. The synthesized catalysts considerably influenced the hydrodeoxygenation activities for the synthesis of lengthy chain hydrocarbons in a stainless-steel reactor with a high-pressure fixed bed between 300 and 375 °C under 10-40 bar hydrogen pressure. High levels of Ni/Pt-ZSM-5 acidity, textural, and H consumption qualities were discovered. Distributions of the products were also reviewed, along with comparisons of the structure-activity connections.
本工作使用高比表面积催化剂研究了非食用油的加氢脱氧(HDO)活性。使用高比表面积催化剂Ni/Pt-ZSM-5以及其他载体(如MCM-48和H-β)对HDO活性进行了全面研究和对比。通过逆序浸渍法制备了负载在介孔ZSM-5上的Ni/Pt双金属催化剂,以促进非食用油的HDO。采用XRD、FT-IR、BET、HR-TEM、HR-SEM、TPD和TGA等技术对制备的催化剂进行了表征。在300至375°C、氢气压力为10 - 40 bar的高压固定床不锈钢反应器中,合成的催化剂对长链烃合成的加氢脱氧活性有显著影响。发现了高水平的Ni/Pt-ZSM-5酸性、织构和氢消耗特性。还对产物分布进行了考察,并对结构-活性关系进行了比较。
