Axens’ commercial hydrocracking catalysts upgrade a wide range of heavy feedstocks to produce the desired slate of products while meeting ultimate quality targets. Depending on operator conversion targets, it relies on a combination of products derived from Grading, Demetallization, Hydrotreatment and Hydrocracking. Scheme on the left represents a typical catalytic arrangement for high conversion single-stage or two-stage hydrocracking.
When associating Impulse® hydrotreating catalysts with Craken® hydrocracking catalysts, reaching the highest performances is possible.
- Impulse® NiMo catalysts are extremely hydrogenating catalysts, which exhibit maximum HDN and HDA activities, and therefore offer an optimum feed preparation for the downstream cracking catalyst, even when processing very refractory feedstocks.
- Craken-D catalysts provide maximized middle distillate yields while improving cold flow properties.
- Craken-Flex catalysts have been developed to optimize middle distillate and naphtha yields, while the hydrotreated Unconverted Oil complies with the most stringent base oil standards
HR 508, based on the ACE technology, ensures a smooth transition of activity between demetallization layers and the superior HDT activity of the Impulse NiMo catalysts.
HR 508 is especially suitable to enhance the stability of the catalytic system.
HRK 658 provides very high hydrodenitrification and aromatic hydrogenation activities, as well as high desulfurization activity.
These features are particularly interesting in the hydrotreatment of VGO feedstocks upstream of hydrocracking catalyst.
