Product Information
TMZ-MTA additive is produced by the proprietary technology of modified Mg-Al hydrotalcite technology.
MgO content near 70%, the attrition, particle size distribution and bulk density of additive are closely match with those of FCC catalyst. The application of this additive will maximize the heavy metals (Vanadium, Nickel,Iron, Calcium) resistance of catalyst and minimize the influence of basic nitrogen in feedback. At the same time, the SO3 discharge form FCC flue gas is minimized.
This additive can bring you significant benefit in heavy resid catalytical cracking especially when feedstock API is lower than 22.3, CCR is over 5%, Ni+V on e-cat is
higher than 7,000ppm.
Benefits of metal trap additives includes:
► Feeding more heavy residue in your RFCCU
► Minimize the addition rate of fresh catalyst and keeping constant conversion
► Trapping heavy metals (Vanadium, Nickel, Iron, Calcium) effectively and naturalize the effect of basic nitrogen and sodium.
► Minimize the delta coke and decrease the regeneration temperature
► Remove SOx in FCC flue gas
Commercial references showed that, after 2 weeks of 8-10% injection of metal trap addition in RFCCU, the feed rate of residue can increase about 25-30%, or feeding heaver feed to the unit(CCR increase 20-25%, total of nickel, vanadium, iron and calcium tolerance increase 15-20%). The conversion rate increase 2-3%, target yield
of liquid product increase 1-2%, the SOx in flue gas decrease 60-70%, fresh catalyst addition rate dropped around 30%, regeneration temperature decreased by 5-10℃, saving 60% caustic or decrease 60% waste salt generated of WGS system at the same time.
