Abstract
Un proceso de alta severidad para la deshidrogenación de un hidrocarburo seleccionado a partir del grupo que consiste en propano y butano en la presencia de un catalizador que incluye platino y un material portador no ácido, se mejora substancialmente reacondicionado periódicamente las partículas resultantes del catalizador desactivadas con coque que contienen platino, mediante el movimiento de las partículas del catalizador a través de una zona de combustión, una zona de secado, una zona de redispersión y una zona de reducción. El secado de las partículas del catalizador inmediatamente después de la combustión del coque, mejora substancialmente la operación de la zona de redispersión de platino. El contenido de humedad más bajo en la zona de redispersión permite tener una reacción de equilibrio entre el cloruro de hidrógeno y el oxígeno por una parte, y el agua y el cloro por la otra parte, para cambiarse a la producción de cloro. Este cambio de la reacción de equilibrio se puede mejorar adicionalmente manteniendo un medio ambiente enriquecido con oxígeno adentro de la zona de redispersión de platino. El uso de una concentración mucho más baja de cloruro de hidrógeno desde la zona de regeneración.A highly stringent process for the dehydrogenation of a hydrocarbon selected from the group consisting of propane and butane in the presence of a catalyst that includes platinum and a non-acidic carrier material, is substantially improved by periodically reconditioning the resulting catalyst particles deactivated with Coke containing platinum, by moving the catalyst particles through a combustion zone, a drying zone, a redispersion zone and a reduction zone. Drying the catalyst particles immediately after coke combustion substantially improves the operation of the platinum redispersion zone. The lower moisture content in the redispersion zone allows for an equilibrium reaction between hydrogen chloride and oxygen on the one hand, and water and chlorine on the other hand, to switch to chlorine production. This change in the equilibrium reaction can be further enhanced by maintaining an oxygen-enriched environment within the platinum redispersion zone. The use of a much lower concentration of hydrogen chloride from the regeneration zone.
