Response Surface Optimization for In-situ Hydrogenation of Acetic Acid as Bio-oil Model Compound

利用自制性能较好的Ni-P非晶态膨润土催化剂,以水热合成反应釜为反应器,研究了乙酸的原位加氢反应工艺。通过单因素实验,考察了反应温度、十氢萘用量、催化剂用量、反应时间对乙酸原位加氢转化率和主要产物选择性的影响。利用响应面实验确定了该催化剂上乙酸原位加氢的最优反应条件:反应温度为294.13℃,催化剂用量为0.31g,十氢萘用量为5.39mL,得到预期乙酸转化率为55.39%。此探讨为进一步研究生物油催化加氢提质提供基础。

In-situ hydrogenation of acetic acid as bio-oil model compound was studied using self-made Ni-P amorphous bentonite catalyst with better performance and hydrothermal synthesis reactor. Single factor experiments were carried out to investigate the effects of the reaction conditions（ reaction temperature, the amount of ten hydrogen naphthalene, the amount of catalyst, the reaction time） on conversion and selectivity of main products from in-situ hydrogenation of acetic acid. The optimal reaction conditions of in-situ hydrogenation of acetic acid were determined by response surface experiments. The reaction temperature was 294. 13 ℃ , the catalyst dosage was 0. 31 g, the dosage of the catalyst was 5.39 mL, and the conversion rate of acetic acid was expected to be about 55. 389%. This discussion was intended to provide a basis for further research on the upgrading of bio-oil by catalytic hydrogenation.
