Definitions

  • U.S. Patent No. 4,257,871 discloses a process for producing olefins from a vacuum residue by first separating, preferably by solvent extraction, the asphalt therein, blending resultant asphalt-depleted fraction with a lighter fraction, e.g., a vacuum gas oil, and then subjecting the blend to a conventional catalytic hydrogenation step prior to thermal cracking.
  • a lighter fraction e.g., a vacuum gas oil
  • the residual fraction comprises heavy tar produced as the product of steam cracking and/or the bottoms product of a vapor liquid separator drum integrated into the steam cracker.
  • the second hydrocarbon stream is a C 4 to C ⁇ Q containing stream and an example composition is given in Table 1 below.
  • the relative amounts of the second hydrocarbon stream and the residual fraction in the third hydrocarbon stream are not particularly limited but, in general, the blend should contain from about 50% to about 90% by weight of the residual fraction.
  • the total amount of oxide modifier present in the catalyst may be between about 0.05 wt% and about 20 wt%, and preferably is between about 0.1 wt% and about 10 wt%, based on the weight of the final catalyst.
  • the methylation process may suitably be carried out in fixed, moving, or fluid catalyst beds. If it is desired to continuously control the extent of coke loading, moving or fluid bed configurations are preferred. With moving or fluid bed configurations, the extent of coke loading can be controlled by varying the severity and/or the frequency of continuous oxidative regeneration in the catalyst regenerator.

Abstract

Dans un processus de valorisation d'hydrocarbures, une charge d'hydrocarbures est traitée dans un vapocraqueur, et/ou un craqueur catalytique, et/ou un cokeur, et/ou un hydrocraqueur, et/ou reformeur, dans des conditions appropriées pour produire un premier flux comprenant des hydrocarbures oléfiniques et aromatiques. Un deuxième flux composé principalement d'hydrocarbures aromatiques et oléfiniques C4 to C12+ est récupéré dans un premier flux et mélangé audit deuxième flux avec une fraction résiduelle provenant d'un vapocraqueur ou d'une unité de distillation atmosphérique ou sous vide pour produire un troisième flux. Le troisième flux est ensuite soumis à une pyrolyse catalytique dans un réacteur, dans des conditions efficaces pour produire un quatrième flux présentant une teneur en benzène et/ou en toluène accrue par comparaison avec ledit deuxième flux et comprenant un sous-produit d'oléfine C3. Le sous-produit d'oléfine C3 est récupéré et le benzène et/ou le toluène sont récupérés dans le quatrième flux.
