Process

Dehydrogenation of lower paraffin hydrocarbons


Product Type

Microspherical chromia-alumina catalyst is applied in petrochemicals to produce monomers for synthetic rubber and methyl tertbutyl ether (MTBE) synthesis. Catalyst АОК-73-24 shows high activity in dehydrogenation of isobutane into isobutylene.

Advantages
High catalytic activity in the temperature range of 540-610°С Competing catalytic activity and performance compared to world counterparts The technology features reduced capital and operating costs vs fixed-bed dehydrogenation The technology is characterized by a low cost of final products Minimal entrainment of the active component, due to the high strength of fixing the active component on the carrier Low consumption rate vs spray-dried catalysts High abrasion resistance with high mechanical strength of the catalyst Uniform particle size distribution ensures optimal hydrodynamic parameters in fluidized-bed reactor Increased service life due to high mechanical strength Catalysts are developed and manufactured in Russia In-house production.

Application

Catalyst AOK-73-24 is applied in a fluidized bed. The isobutane-isobutylene fraction is used as a feed. The dehydrogenation reaction is endothermic and is carried out at a temperature of 540-610°C.

The dehydrogenation section consists of a dehydrogenation reactor and a regenerator. The catalyst circulates between reactor and regenerator. The catalyst is regenerated by coke burning-off.
