This work mainly involved the investigation of the adsorption of thiophene on Cu(I)-supported HY-Al(2)O(3). It demonstrated a high sulfur capacity of 10 mg sulfur/g sorbent when the HY/Al(2)O(3) mass ratio was 3, loaded with 12% copper, calcined at 550 °C, and tested at ambient temperature. In situ Fourier transform infrared (FTIR) and temperature-programmed desorption (TPD) results indicated that the adsorption mechanisms on Cu(I)/HY-Al(2)O(3) primarily were π-complexation and sulfur-adsorbent (S-M; σ) bonds. Pyridine-FTIR showed the total weak Lewis acid contribution to the Cu(I)/HY-Al(2)O(3) adsorption desulfurization performance.
这项工作主要涉及噻吩在负载于 HY-Al(2)O(3)上的 Cu(I)上的吸附研究。结果表明，当 HY/Al(2)O(3)的质量比为 3，负载 12%的铜，在 550°C 下煅烧，并在环境温度下进行测试时，硫容量高达 10mg 硫/g 吸附剂。原位傅里叶变换红外（FTIR）和程序升温脱附（TPD）结果表明，Cu(I)/HY-Al(2)O(3)上的吸附机制主要为π络合和硫-吸附剂（S-M；σ）键。吡啶-FTIR 表明，Cu(I)/HY-Al(2)O(3)吸附脱硫性能的总弱路易斯酸贡献。
