Guard Beds & Adsorbents
Shell Catalysts & Technologies offers a wide variety of guard beds & adsorbents which primarily are used upstream of specific hydrogenation steps giving the necessary protection to downstream catalytic processes.
Solutions to Stay Onstream
Through its wide experience and deep know-how, Shell Catalysts & Technologies offers a range of Guard Beds & Adsorbents which can reduce the possibility of unplanned shutdowns and increasing protections for poison sensitive downstream catalyst units.
Arsine/mercury Adsorbent
Shell Catalysts & Technologies has designed an efficient guard bed to protect downstream catalysts from common poisons, specifically sulphur, arsine, and/or mercury. The adsorbents are designed to operate within the reaction system, at standard operating conditions, eliminating the need for the design of a separate poison guard system.
Sulphur guard bed
Shell Catalysts & Technologies offers a variety of sulphur adsorbents designed to trap specific sulphur species. Sorbents include copper products for light sulphur adsorption and nickel adsorbents for more complex sulphur removal. Shell Catalysts & Technologies also offers absorbent and guard bed solutions specifically for upstream customers in areas such as LPG purification.
Technology That Comprehensively Sustains Output
As owners and operators, Shell Catalysts & Technologies understands the importance and role played by guard beds and adsorbents in safeguarding downstream processes and sustaining process economics.
Guard Bed Reactor Frequently Asked Questions
A guard-bed reactor is a crucial component in many refining and petrochemicals processes. It acts as a protection system for downstream catalysts or equipment. By effectively eliminating impurities and contaminants from the process stream, guard-bed reactors enhance catalyst efficiency, extend catalyst lifespan, minimise deactivation risks, improve overall system reliability, and ultimately elevate the quality of the end product. This section also explores other types of reactor commonly used in refining and petrochemicals, and the advantages of fixed-bed reactors.
What is a guard bed reactor?
What is a guard bed reactor?
A guard-bed reactor is a type of reactor used in certain processes to remove impurities or contaminants from a process stream before they reach the main catalyst bed. These impurities can include sulphur compounds, nitrogen compounds, metals, and other contaminants that can potentially deactivate or poison the catalyst used in subsequent reaction steps.
What are the different types of reactors?
What are the different types of reactors?
The different types of reactors used in refining and petrochemicals include fixed-bed, fluidised bed, ebullated bed, and guard-bed reactors. Fixed-bed reactors feature stationary catalyst beds, while fluidised-bed reactors suspend catalyst particles in a fluidising gas. Ebullated-bed reactors use a fluid-like catalyst bed with upward flow. Guard-bed reactors remove impurities before they reach the main catalyst bed.
What are the advantages of fixed bed reactor?
What are the advantages of fixed bed reactor?
The advantages of a fixed-bed reactor include high conversion and selectivity, improved heat transfer, continuous operation, and the flexibility to choose catalysts. These reactors ensure efficient contact between reactants and catalyst, resulting in enhanced reaction performance and reliable operation for a wide range of processes.
What is the difference between fixed bed and trickle bed reactor?
