Description

Насто щее иэобре:еине относитс к способам очистки катализаторов конверсии углеводородов,от летучих веществ , в частности к способу удалени водорода и углеводородных газов из катализатора риформинга перед его регенерацией.The present invention relates to methods for purifying hydrocarbon conversion catalysts from volatile substances, in particular, a method for removing hydrogen and hydrocarbon gases from a reforming catalyst before it is regenerated.
Известен способ очистки катализаторов конверсии углеводородов от летучих веществ путем продувки катализатора инертным газом, например азотом , под повышенным давлением с последующим сбросом давлени от атмосферного .A known method of purification of catalysts for the conversion of hydrocarbons from volatile substances by blowing the catalyst with an inert gas, for example nitrogen, under elevated pressure followed by depressurization of atmospheric pressure.
Недостатком этого способа вл етс больша длитель ость операции продувки , превышающа врем регенерации катализатора.The disadvantage of this method is the long duration of the purging operation, which is longer than the regeneration time of the catalyst.
Цель изобретени - ускорение процесса очистки.The purpose of the invention is to accelerate the cleaning process.
Дш этого подъем и сброс давлени осуществл ют кратковременными чередующимис импульсами (прот женность каждого импульса не более 60 сек) , повтор их от 2 до b раз, причем газ подают восход щим потоком.Above this, the pressure is lifted and released by short alternating pulses (the length of each pulse is not more than 60 seconds), they are repeated from 2 to b times, with the gas being supplied by the ascending stream.
Применение указанного способа позвоп ет в сопоставимых услови х снизить количество остаточных летучих веществ на катализаторе до 0,5% по The use of this method allows, in comparable conditions, to reduce the amount of residual volatile substances on the catalyst to 0.5% by weight.
сравнению с 2% при непрерывном способе продувки.compared to 2% with continuous purging.
Пример. Порцию катализатора весом от 20 до 90 кг после охлаждени водорюдом или рециркулирующим га зом до загружают в шлюзовой бункер , который представл ет co6of цилиндрический сосуд с конической донной частью и вентил ционной линией, содержащей в верхне- части сосуда ограиичйтельнбе-отверстие дл получени возрастани давлени .Example. A portion of the catalyst weighing from 20 to 90 kg after cooling with hydrogen or recirculated gas is loaded into a lock bin, which is a co6of cylindrical vessel with a conical bottom part and a ventilation line containing in the upper part of the vessel a limited pressure opening.
Водород и нефть удал ют с катализатора введением азотного дуть . При открытой вентил ционной линии объем газа, равный объему шлюзового бункера , добавл ют за период времени, равный 30 сек. Это приводит к возрастанию давлени приблизительно до 0,8 а В конце данного периода времени поток вход }дего в шлюзовой бункер laSoта прекращают, и давление снижают до атмосферного за период времени, равный примерно 36 сек. За врем этой операции вентил ционный газ, содержащий углеводородные газы, удал ют с катализатора. Операции в такой последовательности повтор ют два раза. Затем катализатор, очищенный от водорода и нефти, перенос т в регенерациОнную секцию.Hydrogen and oil are removed from the catalyst by introducing a nitrogen blow. With an open ventilation line, a volume of gas equal to the volume of the lock bin is added over a period of 30 seconds. This leads to an increase in pressure to approximately 0.8 a. At the end of this period of time, the flow of dego into the lock hopper of laSota is stopped, and the pressure is reduced to atmospheric for a period of approximately 36 seconds. During this operation, the vent gas containing hydrocarbon gases is removed from the catalyst. The operations in this sequence are repeated two times. Then the catalyst, purified from hydrogen and oil, is transferred to the regeneration section.
В конце операции очистки катализатор содержит по весу около 0,5 летучих веществ (водорода и углеводородов, имеющих точку кипени ниже ). В сопоставимых услови х после непрерьлвной Прюдувки одинаковым количеством азота в течение этого же периода времени катализатор может содержать по весу около 2% летучих веществ.At the end of the cleaning operation, the catalyst contains by weight about 0.5 volatile substances (hydrogen and hydrocarbons having a boiling point below). Under comparable conditions after continuous Prudukovka with the same amount of nitrogen during the same period of time, the catalyst may contain by weight about 2% of volatile substances.
