Reactor Jing 150-230 DEG C drying 12-24h are put into, then roasting 2-5h is obtained urging for dehydrogenating propane at 500-700 DEG C
Agent.
The catalyst slurry is 30-80% by the solid content being mixed to prepare of one or more in selenium, tellurium, silicon and water
Serosity.
Preferably, step 1）In each raw material weight degree be：Aluminium hydroxide 42%, boehmite 38%, field
Cyanines glue 9.5%, sodium silicate 3%, water 7.5%.
The invention has the beneficial effects as follows：Research and develop new propane dehydrogenation catalyst and there is advanced technical characterstic：1st, product is not
Pretreatment is needed, can directly be entered device reaction, be eliminated the complex techniques processes such as desulfurization, dearsenization, deleading.2nd, filler is applied to third
The individually dehydrogenation such as alkane, iso-butane, while being also adapted to the mixing dehydrogenation for propane with butane.3rd, your gold catalyst not exclusively relies on
Category, adopts base metal for main body；Mechanical is corroded, and reduces the cost of product.4th, regeneration is conducive to without oxychlorination condition
Device is long-term, stable and safe operation, the advantages of reducing energy consumption.5th, the reactivation heat of catalyst can make circulation profit with return system
With can turn that the thermal efficiency is high, low power consumption and other advantages according to circulated heat controlling reaction temperature.
