Product introduction

The paraffin oil isobutane dehydrogenation catalyst has few impurities, good stability, high-purity activated alumina as the carrier, and Cr2O3 as the main active component. At the same time, rare earth special additives are added to ensure that the catalyst has high activity, high selectivity and good anti-carbon performance.

The catalyst can be used in fluidized bed, moving bed and fixed bed reactors.

Under a certain temperature and pressure, part of the isobutane in the feed gas undergoes dehydrogenation reaction under the catalytic action of the catalyst to generate isobutene, which is then separated and purified to obtain a high-purity target product.(C4H10→C4H8+ H2)

Service Condotions:

1. Airspeed: 100～1000h-1;

2. Operating temperature: 550～600 ℃;

3. Regeneration temperature: 620～650 ℃;

4. Pressure: Normal pressure ~ 1.0 Mpa.

Product Basic Info

The process of isobutane dehydrogenation to isobutene is divided into two categories: direct dehydrogenation and oxidative dehydrogenation.

Among them, the direct dehydrogenation reaction is a strong endothermic process and needs to be carried out at high temperature; while the oxidative dehydrogenation is different from the direct dehydrogenation, which is not limited by thermodynamics and can be carried out at 400 °C.

The paraffin oil isobutane dehydrogenation catalyst is suitable for both direct dehydrogenation of isobutane and oxidative dehydrogenation.

Among them, the oxidative dehydrogenation reaction temperature is 200-400 °C, and the direct dehydrogenation reaction temperature is above 500 °C. Species identified on the surface of fresh paraffin oil isobutane dehydrogenation catalysts include Cr2+, Cr3+, Cr5+, Cr6+, and α-Cr2O3 crystals, depending on the pretreatment method, Cr loading and precursor species, calcination temperature, and support properties.
