一种用于精苯深度脱硫的吸附剂及其制备方法
摘要：
本发明提供一种用于精苯深度脱硫的吸附剂及其制备方法，该吸附剂以氧化铝或以钾钠镧改性的氧化铝为载体负载贵金属钯，以重量计其至少包括以下组分：贵金属钯含量0.3~1.5%；钠含量0~3%；钾含量0~3%；镧含量0~5%；剩余含量为氧化铝载体。尤以油柱成型法制造的氧化铝为载体负载贵金属钯脱硫效果最好。该吸附剂该吸附剂对硫具有强吸附能力，能将精苯中总硫从1ppm降到0.01ppm以下，并且该吸附剂硫容大。
摘要（英）：

The invention provides an adsorbent for deep desulfurization of refined benzene and a preparation method thereof. With alumina or sodium-potassium-lanthanum modified alumina as carrier-loaded noble metal palladium, the adsorbent at least comprises the following components in percentage by weight: 0.3-1.5 % of noble metal palladium, 0-3 % of sodium, 0-3 % of potassium, 0-5 % of lanthanum and the balance of alumina carrier. A best desulfurization effect is obtained if the alumina manufactured by using an oil column molding method is used as the carrier-loaded noble metal palladium. The adsorbent provided by the invention has the advantage of strong adsorbing capacity to sulfur and large sulfur capacity; and the total sulfur in the refined benzene can be reduced from 1 ppm to less than 0.01 ppm.
