Title: PERRMANCE ASSESSMENT OF CATALYST ACTIVITY IN FLUID CATALYTIC CRACKING UNIT
Authors: CHUKWUNONSO, IFEACHQ
Issue Date: Nov-2008
Abstract: The study was aimed at assessing the performance of tatalyst activity in a fluid catalytic I i I cracking unit. The extent to which the feed is con~erted to the desired product (i.e. I I conversion) was used as basis. i ! A given model which was tested using the known operating variables was used to assess the I effect of changes in the values of the operating parameterf on the performance of the catalyst activity. It was discovered that high catalyst-to-oil ratiQ, reaction temperature, and micro! activity test favours the performance of the catalyst a~tivity and increasing the feedrate without a proportionate adjustment of the other process 1ariables decreases the performance of the catalyst activity. It was detelmined that for Im3/hr rise in feedrate, the co&esponding temperature adjustment I should be about OAoC and such adjustment must be done gradually to avoid thermal shock on I I the catalyst, the operating allowable temperature limit must not be exceeded and the I deactivating temperature of the catalyst must not be reacped. Erractic catalyst flow in stand pipes was determined to be the major problem in the op1ration of a fluid catalytic cracking unit.
