Industry-leading FCC Pretreatment Catalyst Solutions
Refiners worldwide are reporting significantly enhanced refinery economics after working with Shell Catalysts & Technologies to optimise the performance of their integrated Fluid Catalytic Cracking (FCC) complexes.
Shell Catalysts & Technologies offers a range of industry-leading FCC pretreatment catalyst solutions and works closely with refiners to design catalyst systems that match their specific performance goals. We follow a highly diagnostic process in which we listen to customers to gain a thorough understanding of their situation. This enables us to devise a value-adding catalyst system designed to lie within those constraints and leverage the most value from their assets.
Success in this application with a large variety in feeds and objectives requires catalyst systems that combine main-bed catalyst performance with SENTRY portfolio protection from poisons and foulants ; integrated offerings for improved process performance upstream, internal, and downstream from the CFH; and technical excellence to develop, monitor and optimise unit performance
Sustaining leadership in this application comes through the cornerstones of ensuring day-to-day performance together with continuous improvement, technical expertise, and focused research & development program that has been providing market leading FCCPT solutions for years. These cornerstones are enabled by broad based refining knowledge, an ability to engage, diagnose, develop and lead change and an ability to gain customers trust and grow long-term relationships.
Building on the proven capability and reliability of the CENTERA™ technology platform, Criterion is now delivering the CENTERA GT™ level of performance. In the FCC Pretreat application, performance is measured by many metrics and success is achieved through the application of a custom designed catalyst system. Enabling continued FCCPT performance gains, three new products have been developed providing top-tier performance in HDS, HDN, and AroSat while maintaining the proven stability and contaminant tolerance Criterion FCCPT catalysts have been well known for.
|DN-3655||FCC Pretreat|| |
CENTERA GT DN-3655, a step-out Type II nickel-molybdenum catalyst for FCC feed pretreatment (FCC-PT). Compared to previous generations, CEN-TERA GT DN-3655 provides significant nitrogen removal (HDN) and sulfur removal (HDS) improvements. It is especially well-suited for high quality FCC feed production in moderate to high pressure units processing difficult feeds, where nitrogen removal and hydrogenation reactions are valued to improve FCC conversion levels.
CENTERA GT DN-3655 enhances HDS and HDN performance and stability across a broad range of scenarios, particularly in high severity applications that require maximum activity to overcome unit limitations. Applications where DN-3655 is particularly well-suited include:
|DN-3651||FCC Pretreat||CENTERA® DN-3651 is Shell Catalysts & Technologies’ is an industry proven high activity NiMo catalyst for moderate-to-high pressure FCC Pretreat operation. DN-3651 has very high HDS and HDN activity while it maintains ASCENT stability and metals capacity for improved cycle performance with exceptional polyaromatic saturation optimising FCC conversion|
|DN-3551||FCC Pretreat||ASCENT DN-3551 is a widely used proven catalyst featuring high activity, exceptional metals capacity and stability for improved cycle performance and reliability when processing difficult feedstocks.|
|CENTERA GT DC-2655|| |
CENTERA GT DC-2655 is a new Type II Co-Mo with Ni promoter catalysts for FCC-PT service providing step-out gains in performance from previous generations. Enhances FCC Pretreat performance and stability across a broad range of scenarios, particularly in applications that require very high activity to overcome unit limitations. Applications where DC-2655 is particularly well suited:
|CENTERA™ GT DC-2656|| |
CENTERA™ GT DC-2656 is a new Type II Co-Mo with Ni promoter catalysts for FCC-PT service providing step-out gains in performance from previous generations. Provides the deep desulfurisation required to meet clean fuel requirements and flexibility to process heavier feeds, maximise ULSD cut points, and extend unit cycle length. DC-2656 is especially suited for high quality FCC feed production in moderate-to-high pressure units where desulfurisation (HDS), denitrification (HDN), and hydrogenation reactions improve FCC conversion and reduce sulfur related operational constraints. Either by itself or combined with a customised catalyst system, DC-2656 generates balanced performance and superior FCC feed quality across a broad range of high severity scenarios requiring maximum activity. Applications where DC-2656 is particularly well-suited include:
