AMBER™

AMBER catalysts are frequently used, high-quality catalysts from the Albemarle portfolio and are manufactured using ADM-20 matrix technology, which is common to its high-accessibility catalysts. AMBER is the benchmark for maximum transportation fuels against which all other gas oil catalysts are measured. In addition, AMBER catalysts are solutions for non-residue processing refiners that require excellent bottoms conversion and the gasoline and olefin selectivity that these catalysts offer.

AMBER catalysts possess high accessibility (high mass transfer, as measured by the Albemarle Accessibility Index, AAI). Albemarle FCC catalysts feature the highest AAI in the industry. The high-accessibility structure offers large heavy feed molecules quick access to the active sites and facilitates rapid egress of the products without secondary reactions (Figure 1).

AMBER catalysts contain specialty ADZ zeolites with high activity and exceptional hydrothermal stability. The advanced matrix technology (ADM‑20) in AMBER catalysts protects the zeolite, thereby enhancing its activity and enabling selective cracking of bottoms to the lowest possible levels.

The advantages of AMBER are
- maximized gasoline and distillates production
- improved bottoms conversion and higher intrinsic activity
- controlled hydrogen transfer and overcracking, which results in higher LPG olefinicities
- improved resistance to poisons (nitrogen, coke and metals)
- improved strippability.
