2020 CATALYST HANDBOOK INDUSTRY CATEGORIES PROCESS CATEGORIES COMPANY INDEX REFINING FCC DURASOx-N Application: Reduction of SOx in flue gas from fluid catalytic cracking units. Description: DURASOx-N contains multiple technologies (Fig. 1) that capture sulfur in the regenerator and release it on the riser side as H2S, which most refiners can then process by the Claus process. DURASOx-N contains a high level of both magnesium (the capturing agent) and catalytic metals for SOx capture. Advantages: High activity and low attrition. Suitable for units sensitive to losses and opacity. Refiners can use DURASOx-N as part of an overall plan to comply with environmental regulations and consent decrees with the EPA. Economics: DURASOx-N is a preferred additive when refinery economics favor an additive solution vs. operating a caustic scrubber. A refiner may also defer capital investment in a scrubber by using DURASOx-N. Catalyst system * Cerium/vanadium co-metal Matrices * Synthetic hydrotalcite Binders * Synthetic, integral binder DuraSOx-N is built on Albemarle's hydrotalcite technology Fig. 1. DURASOx-N catalyst details. Development: Compatible with all of Albemarle's FCC catalysts.
