Abstract

In this study, Ni/TiO₂/NaX zeolite nanoparticles were synthesized by hydrothermal and wet inoculation methods and characterized by XRD, FTIR, SEM, EDXA, TEM, and BET/BJH techniques. Desulfurization of gasoline under visible light was investigated in a batch reactor under mild conditions. Response surface methodology with central composite design was used to investigate mass of Ni/TiO₂/NaX zeolite nanoparticles as a photocatalyst and mass of NaX zeolite as adsorbent effects on conversion and process optimization. According to the experiments, the optimum conditions for the desulfurization of gasoline was determined with conversion percent of 92.29% with Ni/TiO₂/NaX zeolite nanoparticles (0.68) and NaX zeolite adsorbent (0.84 g). In addition, the results showed that NaX zeolite adsorbent in the adsorption process has a high effect on gasoline desulfurization.

轻度条件下基于NaX沸石的光催化氧化/吸附对汽油燃料进行脱硫：通过中央复合设计优化工艺

摘要

在本研究中，通过水热和湿法接种方法合成了Ni / TiO ₂ / NaX沸石纳米粒子，并通过XRD，FTIR，SEM，EDXA，TEM和BET / BJH技术对其进行了表征。在温和的条件下，在间歇式反应器中研究了可见光下汽油的脱硫。使用具有中心复合设计的响应表面方法，研究了Ni / TiO ₂ / NaX沸石纳米颗粒的质量作为光催化剂，以及NaX沸石的质量作为吸附剂对转化和工艺优化的影响。根据实验，确定了Ni / TiO ₂转化率为92.29％的最佳汽油脱硫条件。/ NaX沸石纳米颗粒（0.68）和NaX沸石吸附剂（0.84 g）。另外，结果表明，NaX沸石吸附剂在吸附过程中对汽油脱硫的影响很大。
