应用：痕量噻吩测定

苯是重要的化工原料,我国焦化苯资源极为丰富,但其应用受到了精制工艺的制约。针对目前焦化苯精制中催化加氢法操作费用高、消耗氢气；硫酸酸洗法脱硫精度低、污染环境；萃取精馏法设备投资大、萃取剂耗量多、循环利用性差；以及下游产品合成对原料苯中硫含量要求非常严格的现状,提出了一种脱硫精度高、操作方便、能耗低、环保、经济可行且能回收利用噻吩的焦化苯提质工艺。

浩瀚色谱（山东）应用技术开发有限公司，采用新方法，研发的填充柱，分析时间短，柱效高，苯和噻吩完全分离，结果满意。

Special column for the determination of thiophene in coking benzene Details:

Name: thiophene packed column

Stationary phase: dedicated

Model: HH-Thiophene2021

Application: Determination of trace thiophene



Benzene is an important chemical raw material. my country is extremely rich in coking benzene resources, but its application is restricted by the refining process. In view of the high operating cost and hydrogen consumption of the current catalytic hydrogenation method in the refining of coking benzene; the sulfuric acid pickling method has low desulfurization accuracy and pollutes the environment; the extractive distillation method has large equipment investment, high extractant consumption, and poor recycling; and downstream product synthesis In the current situation that the sulfur content in the raw material benzene is very strict, a coking benzene upgrading process with high desulfurization accuracy, convenient operation, low energy consumption, environmental protection, economically feasible and recyclable thiophene is proposed.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. adopted a new method and developed a packed column with short analysis time and high column efficiency. Benzene and thiophene were completely separated and the results were satisfactory.
