Abstract
Inventia de fata se refera la un procedeu de regenerare a unui catalizator utilizat în procedee de cracare catalitica în faza fluida (FCC), dar aceasta se poate folosi în orice procedeu în care se arde carbune sau cocs pe un catalizator solid, sub forma de particule. Procedeul consta în arderea carbunelui depus pe catalizatorul contaminat si dezactivat, la o temperatura cuprinsa între 640 si 760 degree C si împartirea catalizatorului în doua parti, din care a doua portiune se reintroduce în arzator. înainte de trecerea în arzator, portiunea a doua de catalizator regenerata, sus-mentionata, este combinata cu catalizator dezactivat si cu o prima portiune din gazul de regenerare sus-mentionat, care contine oxigen, pentru a forma o faza densa într-o zona verticala de amestecare-ridicare, plasata între punctul de introducere al primei portiuni de gaz de regenerare continînd oxigen si punctul de introducere al celei de-a doua portiuni a gazului de regenerare continînd oxigen, care este introdus la partea inferioara a arzatorului în zona de amestecare-ridicare, catalizatorul avînd o densitate de 0,160 si 0,558 kg/dm3, viteza superficiala a gazului de regenerare fiind cuprinsa între 0,03 si 4,57 m/s, temperatura între 480 si 760 degree C, iar raportul între catalizatorul regenerat si catalizatorul consumat fiind cuprins între 1:3 si 4:1.The present invention relates to a process for the regeneration of a catalyst used in fluid catalytic cracking (FCC) processes but this can be used in any process in which coal or coke is burned on a solid particulate catalyst . The process consists in burning the deposited carbon on the contaminated and deactivated catalyst at a temperature of between 640 and 760 ° C and dividing the catalyst into two parts, from which the second portion is reintroduced into the burner. Prior to switching to the burner, the second portion of the above-mentioned regenerated catalyst is combined with the deactivated catalyst and a first portion of the above-mentioned regeneration gas containing oxygen to form a dense phase in a vertical zone between the point of introduction of the first oxygen-containing regeneration gas portion and the point of introduction of the second portion of the oxygen-containing regeneration gas which is introduced at the lower side of the burner into the mixing zone- the catalyst having a density of 0.160 and 0.558 kg / dm3, the superficial velocity of the regeneration gas being between 0.03 and 4.57 m / s, a temperature between 480 and 760 degrees C, and the ratio between the regenerated catalyst and the spent catalyst ranging from 1: 3 to 4: 1.
