Special column for determination of thiophene in coking benzene
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.
