摘要
采用自主研发的铜硅催化剂EG-805进行草酸酯加氢制乙二醇工业侧线试验。在空速0.5 h^(-1)和氢气与草酸酯质量比120条件下,热点温度(178~180)℃,低于工业催化剂热点温度约15℃,草酸二甲酯转化率100%,乙二醇选择性96.0%~97.8%。该催化剂累计运行1 118 h,满负荷连续稳定运行1 006 h,运行期间热点无明显位移,稳定性良好。
Industrial side -stream experiment was carried out over self- developed copper -silicon cata- lyst EG - 805. When liquid velocity was 0.5 h -1 and hydrogen ester mass ratio was 120, hot spot tempera- ture was （178- 180） ℃ which was lower than that of industrial catalyst more than 15℃ ,dimethyl ox- alate conversion was 100%, selectivity of ethyl glycol was 96.0% - 97.8%. The catalyst had been run- ning for 1 118 h, 1 006 h at full load. Hot spot shift was little. EG - 805 catalyst posed good stability.
