The maleic anhydride catalyst (n-Butane method)

Brand Name: YMA5601

Application scenario: maleic anhydride synthesis for n-butane oxidation in fixed bed

Technical features: high activity, high selectivity, high air speed, high butane concentration, low butane consumption, low double acid impurity content, high strength, low pulverization rate, high life

Advantages and characteristics:

1、 Higher yield: high-density catalysts have more active centers compared to low-density catalysts, and could achieve higher air speed and higher selectivity at lower temperature, achieving higher maleic anhydride yield, device yield, and life.

2、 Lower consumption: ensure the crude maleic anhydride yield at the reactor outlet, help the maleic anhydride unit to improve and optimize the control of butane and solvent consumption, and reduce the operating cost.

3、 Longer cycle: The significant reduction of the by-product reduces the formation of polymers in downstream equipment, reduces the frequency and time of parking cleaning equipment, and extends the operating cycle.

4、 Lower waste water: achieve lower sewage production with the support of Yussen group experts.

5、 MA Operating Experience: Yussen is both a maleic anhydride factory and a maleic anhydride catalyst manufacturer. Yussen group now has a single set of production capacity of 150,000 tons of maleic anhydride production equipment, and the product quality is excellent. Maleic anhydride units with a capacity of 290,000 tons are under construction. Rich experience in efficient operation, normal maintenance and abnormal handling of maleic anhydride unit catalyst.

6、Technical support: the professional technical service team provides guidance for the whole reaction system redesign; provides continuous technical support during the catalyst life cycle to optimize the performance; quickly and effectively solve the abnormal problems of the catalyst using process.
