Determination of Oxygen and Nitrogen in Butadiene Produced by Oxidative Dehydrogenation of Butene by Packed Column
Packed column for determination of oxygen and nitrogen in butadiene oxidative dehydrogenation of butene

Name: Packed column
Specification: 3m*3mm
Model: 5A

Using H-198 iron-based catalyst, the actual operation of butadiene oxidative dehydrogenation to butadiene is carried out on a φ3.4m fluidized bed. The influence of factors such as raw material composition, reaction temperature, oxygen-to-olefin ratio, water-to-olefin ratio, butene space velocity and catalyst in the production process on the operation is discussed. The suitable operating conditions are considered as follows: the content of isobutylene in the raw materials is ≤0.5% (mass), the reaction temperature is 375±8°C, the inlet pressure of the reactor is 0.039-0.059 MPa, the oxygen-to-ene ratio is 0.65-0.70 (mol ratio), and the water-to-ene ratio is 6- 10 (mol ratio), butene space velocity 185-200h~(-1). Under these conditions, the butadiene yield can reach 63.25%, and the selectivity can reach 87.8%.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses a 5A molecular sieve packed column to determine the content of O2 and N2 in the production of butadiene by oxidative dehydrogenation of butene. The column efficiency is high, the separation is good, and the results are satisfactory.
