Title (EN) CATALYTIC CRACKING METHOD FOR TREATING A FRACTION HAVING A LOW AMOUNT OF CONRADSON CARBON
(FR) PROCEDE DE CRAQUAGE CATALYTIQUE POUR LE TRAITEMENT D'UNE COUPE A FAIBLE CARBONE CONRADSON.
Abstract:
(EN) The invention relates to a method for the catalytic cracking, using a fluidized bed, of a slightly coking Conradson carbon feedstock of no more than 0.1 wt % and having a hydrogen content of no less than 12.7 wt %, said method including: at least one step of cracking for the feedstock; a step for separating/stripping the effluents of the coked catalyst grains; and a step of regenerating said grains. The method is characterized in that at least one so-called coking carbon or hydrocarbon effluent, having an aromatic-compound content of more than 50 wt % and including more than 20 wt % of polyaromatic compounds, is recirculated over the homogeneously-distributed slightly-coking catalyst before regeneration in order to adjust the delta coke of the method.
(FR) Procédé de craquage catalytique à lit fluidisé d'une charge faiblement cokante de carbon conradson inférieur ou égal à 0,1 % poids et de teneur en hydrogène supérieure ou égale à 12,7 % poids comprenant au moins une étape de craquage pour la charge, une étape de séparation/stripage des effluents des grains de catalyseur cokéset une étape de régénération desdits grains, le procédé étant caractérisé en ce que on recycle sur du catalyseur distribué de façon homogène et faiblement coké avant régénération,au moins un effluent carboné et/ou hydrocarboné dit cokant de teneur en composés aromatiques supérieure à 50% poids, comprenant plus de 20% en poids de composés poly-aromatiques pour ajuster le Delta coke du procédé.
