MIXING METHODS AND SYSTEMS TO FEED CATALYST PRECURSOR INTO STOCK CONTAINING LOW-GRAVITY OIL Russian patent published in 2011 - IPC B01J8/00 B01F13/00 C10G11/00 

FIELD: process engineering.

SUBSTANCE: invention may be used in petrochemical industry. Catalyst precursor 202 is first mixed with thinner 204 to produce diluted catalyst precursor 207. Stock 208 containing low-gravity oil with viscosity exceeding that of catalyst precursor 202 is divided into two flows 208a and 208b. First flow 208a contains 30% to 90% of stock 208. Diluted catalyst precursor 207 is mixed with first stock flow 208a to produce mixed composition of oil stock to be mixed with residual part of stock 206b that contains low-gravity oil.

EFFECT: efficient dispersion of catalyst precursor.
