Abstract

Refineries processing heavy, high metals feedstocks have reused other refineries' spent cracking catalyst for the past ten years without observing any yield debits. ChemCat has developed a process whereby a refinery can reuse its own spent catalyst without suffering any yield debits. The new DEMET process is being demonstrated in the world's first commercial fluid cracking catalyst rejuvenation and demetallization plant. The plant is located in Meraux, Louisiana and processes 20 tons/day of spent cracking catalyst for local refineries. The plant removes contaminant metals from zeolite catalysts, while simultaneously increasingly the zeolite and matrix surface areas. The demetallized catalyst has a higher activity and better selectivity than the undemetallized spent catalyst. The demetallized catalyst is also more hydrothermally stable than the spent catalyst. ChemCat's DEMET process enables refiners to eliminate the high cost of spent FCCU catalyst disposal and to significantly reduce their consumption and cost of fresh catalyst.

DEMET-process for demetalization of fluid cracking catalysts

Conference Elvin, F; Otterstedt, J; Sterte, J - American Chemical Society, Division of Petroleum Chemistry, Preprints; (USA)

The control of the activity and selectivity of FCCU catalyst is the key to optimum yields and maximum profitability. Currently, refineries employ two methods of control: the addition of fresh catalyst, and the addition of good quality equilibrium catalyst. Onsite FCCU catalyst demetalization, called DEMET, is a third alternative which has been developed by ARCO and the ChemCat Corporation. The DEMET concept is based on thirty years of research and development by ChemCat, ARCO and its predecessors. The DEMET procedures are used to remove active metal contaminants from the surface of equilibrium catalysts. This results in increased activity and improvedmore »« less
Fresh, spent and dematallized spent FCCU catalysts characterized by detailed elemental analysis of powder and leachate

Conference Pavel, S; Elvin, F

Elemental analyses of spent Fluid Catalytic Cracking (FCCU) catalyst powders and leachates are necessary to characterize the total FCCU catalyst system and any potential environmental considerations. Fresh, spent, and demetallized spent FCCU catalysts were leached by various methods and in accordance with the Toxicity Characteristic Leaching Procedure (TCLP). TCLP results were compared to Land Disposal Restrictions--Phase II (LDR-II) Universal Treatment Standards (UTS). The DEMET process takes a portion of the spent catalyst and removes a portion of the metal contaminants, enabling the refiner to recycle demetallized spent FCCU catalyst, thus reducing the solid waste by on-site or off-site processing.

Vanadium poisoning effect on catalyst isolated

Journal Article Elvin, F - Oil Gas J.; (United States)

Extensive testing of commercial FCCU catalysts has shown that when all metals are removed by demetallizing the catalyst, the catalyst is effectively reactivated. But because vanadium is the primary metal associated with catalyst activity, it is important to understand the effect on catalyst activity when only the vanadium is removed. To isolate the vanadium effect on catalysts, ChemCat Corp. has performed tests on various nonzeolitic amorphous catalysts, zeolitic rare earth (REY) catalysts, and zeolitic ultra-stable (USY) catalysts where the vanadium was the only metal removed. Results were compared to reactivation by the Demet process, which effectively removes the vanadium asmore »« less
Reactivation and passivation of equilibrium FCCU catalyst

Conference Elvin, F

ChemCat has developed a new catalyst rejunvenation process, DEMET, which reactivates fluid catalytic cracking catalyst as it removes contaminant metals. The new process both prevents and reverses thermal deactivation, deactivation due to metals, and deactivation due to nitrogen compounds. It also increases both zeolite and total surface area, although the zeolite unit cell size remains unchanged. The rejuvenated catalyst makes 14% more gasoline and 70% less hydrogen than the unrejuvenated catalyst at constant coke yield and constant reactor temperature. The new process can reduce FCCU catalyst consumption by over 90%, and in the future, fresh catalyst will only be requiredmore » to compensate for unit losses.« less
New FCCU DEMET{reg_sign} process to produce demetallized spent catalyst with high activity and low hydrothermal deactivation rates

Miscellaneous Pavel, S; Elvin, F

Fluid Catalytic Cracking is a valuable refining process to upgrade heavy hydrocarbons to high valued products. During the cracking reaction, catalyst is contaminated by deposited metals from feedstocks which include nickel, vanadium, et al. To compensate for decreased FCCU feedstock conversion and product selectivity, a portion of the circulating catalyst equilibrium inventory is withdrawn for spent catalyst disposal, and fresh catalyst is added to the system. DEMET{reg_sign} is a valuable process to demetallize spent catalyst for recycle to the FCCU. The DEMET receives a portion of the spent catalyst and removes a portion of the metal contaminants, enabling the refinermore »« less
