通过开发用于含氧有机物加氢脱氧（HDO）过程的高效催化剂，对升级的生物燃料生产工艺进行了研究。结果表明，在温和条件下，Ni-Cu催化剂比单一Ni催化剂具有更好的加氢性能。铜在低于300°C的温度下促进氧化镍还原。此外，铜在280-350°C下防止含氧有机物的甲烷化。催化剂载体在含氧化合物的加氢处理中也起关键作用。催化剂载体的筛选表明，CeO 2和ZrO 2是最有效的目标过程中，因为可能的额外的活化的含氧化合物的载体表面上。所制备的催化剂具有非硫化性质，可用于低硫含量生物液体的改质。
The investigation of upgraded bio-fuels production processes was carried out via the development of efficient catalysts for oxy-organic hydrodeoxygenation (HDO) processes. It was found that Ni–Cu catalysts are more attractive than single Ni catalysts in HDO under mild conditions. Copper facilitates the nickel oxide reduction at temperatures lower than 300°C. Moreover, copper prevents methanization of oxy-organics at 280–350°C. The catalyst supports play also a key role in hydrotreatment of oxygen-containing compounds. Screening of catalyst supports showed that CeO2and ZrO2are most effective in the target processes because of possible additional activation of oxy-compounds on the support surface. The prepared catalysts have non-sulfided nature and can be used for upgrading of bioliquids with a low sulfur content.
