Ebullating Bed Resid (EBR) for bottoms cracking and upgrading uses DCS, ECAD, LS, HSLS, and HCRC® series solutions. EBR systems provide contaminant removal central to control of sediment formation and maximum desulfurization activity for transportation fuel specifications. ART EBR systems are the answer to high resid conversion to distillate and VGO, low sediment in reactor effluent, lower sulfur in bottoms for fuel oil and low sulfur fuel producers, good MCR conversion and the highest possible HDN.
Designed by ART’s technical experts, catalyst systems, including dual catalyst systems, are customized using state of the art and tailor-made catalysts in all platforms to meet diverse and changing needs. Our catalyst systems are optimized for different feeds and provide flexibility to customize support properties and metals function.
DCS
ART’s demetallization catalyst technology was commercialized in the 1980s to address very high contaminant feeds and for use in the first stage of the multi-reactor systems. The very high pore volume with good attrition characteristics and excellent sediment control allows EB refiners to achieve very high catalyst utilization rates. This EB catalyst is the industry benchmark for very high metals capacity.
ECAD
ART’s ECAD catalysts were developed to offer high metals capacity and good HDS and HDMCR conversion.
Its key features are very good metals capacity for high feed contaminant metals and good HDS and HDMCR conversion activity, at very good sediment control. This platform allows lower catalyst addition rates, and/or the flexibility to process more difficult and opportunity crude feedstocks.
LS
LS Catalyst is low sediment technology used for a wide array of feedstocks, including heavy crudes.
ART has developed several technology platforms to achieve different benefits within specific EBR unit constraints. The LS platform was the first commercially available EBR catalyst to provide low sediments for a variety of feeds including the very difficult Urals VR.
HSLS
The HSLS platform provides high sediment control (very low Sediment/Resid Conversion ratio) with very good HDS and HDMCR conversion.
This proven catalyst system offers the most optimum catalyst usage in the first stage or as standalone in the multi-reactor catalyst system. The HSLS catalyst technology has been extremely successful for a wide variety of feedstocks, and allows very high flexibility to maximize resid conversion most economically with low catalyst addition rate.
HCRC®
The HCRC® catalyst platform offers ultra-high HDS activity for EBR hydrocracking.
Refiners can move their EBR RHC units to higher catalytic and lower thermal conversion and still meet increasingly stringent requirements for ultra-clean fuels (VTB Sulfur).
The catalyst is intended for use after the first stage of the multi-reactor system, and in combination with the DCS, ECAD or HSLS platforms.
HCRC catalysts offer higher resid conversion and improvements in HDS, HDMCR, HDN and product API. This platform gives refiners the flexibility to move to a lower reaction severity to significantly reduce sediment/coke formation, maximizing operability in the EB RHC process.
