Through technological expertise and collaborative solutions, Shell Catalysts & Technologies enables refiners to maximize Hydrocracking performance

Shell Catalysts & Technologies hydrocracking catalysts not only have been in use for decades, but they can be currently found in about 850 hydrotreating units around the world used for product quality upgrading and hydrocracker pretreatment.

These solutions provide refiners with valuable feedstock and product slate flexibility. Several businesses have taken this flexibility to the next level.

Many have adapted their hydrocracking units to handle extreme feeds, while others have transformed their operations and strategies to take advantage of new business opportunities in oil to chemicals (OTC), clean fuels or lubricant base oils. In so doing, these refiners have unlocked some real performance differentiators and transformed the economics of their assets.

Advanced Catalysts for Comprehensive Value

Shell Catalysts & Technologies offers a broad range of zeolite catalysts to satisfy a variety of refinery hydrocracking objectives. We also provide the pretreatment catalysts that are vital to preserving the function of the main cracking catalysts.

We work closely with refiners to select the most appropriate hydrocracking and pretreatment catalysts. This involves a detailed analysis in which reference will be made to feedstock quality; the desired product slate; the design of the hydrocracker and its normal operating regime; the amount of hydrogen available; and the target cycle length. Process modelling and pilot plant trials are part of the toolbox used to pinpoint the best catalysts for individual hydrocrackers and also to develop the most effective unit operating strategy.
