Abstract

Human efforts to overcome environmental problems from using fossil fuels continue, such as hydroconversion of biomass into bio-jet fuel. Research on producing a jet fuel range of bio-hydrocarbons from used palm cooking oil catalyzed by sulfated zirconia impregnated with nickel-molybdenum bimetal has been successfully conducted. The hydrothermal method synthesized the nano-catalyst material in the sulfation and impregnation processes. The hydroconversion process was carried out at atmospheric pressure and a temperature of 300–600 °C for 2 h with a hydrogen gas flow rate of 20 mL/min and a catalyst-to-feed ratio of 1:100 (wt%). Compared with zirconia and sulfated zirconia, NiMo-impregnated sulfated zirconia showed the best activity and selectivity in bio-jet fuel production with liquid product and selectivity of 61.07% and 43.49%, respectively. This catalyst also performed well in three consecutive runs, with bio-jet fuel selectivity in the second and third runs of 51.68% and 30.86%, respectively.

水热法制备的硫酸化氧化锆纳米催化剂上分散的镍钼在将废棕榈烹调油转化为喷气燃料系列生物烃中的表现

人类一直在努力克服使用化石燃料带来的环境问题，例如将生物质加氢转化为生物喷气燃料。利用硫化氧化锆浸渍镍钼双金属催化废棕榈食用油生产生物烃类喷气燃料的研究已经取得成功。在硫酸盐化和浸渍过程中，水热法合成了纳米催化剂材料。氢气流速为 20 mL/min，催化剂与原料的比例为 1:100（重量比），在常压和 300-600 °C 的温度下进行了 2 小时的水热转化过程。与氧化锆和硫酸化氧化锆相比，镍钼浸渍硫酸化氧化锆在生物喷气燃料生产中表现出最好的活性和选择性，液体产物和选择性分别为 61.07% 和 43.49%。这种催化剂在连续三次运行中也表现出色，第二次和第三次运行中的生物喷气燃料选择性分别为 51.68% 和 30.86%。作者版权所有 © 2024 年，BCREC 出版集团出版。本文采用 CC BY-SA 许可协议 (https://creativecommons.org/licenses/by-sa/4.0) 公开发表。
