For refineries, selecting the top hydroprocessing catalyst is crucial. This choice can have a major impact on the efficiency of a refinery’s process, as well as product quality and environmental compliance. The factors we explore in this article are those that need to be considered before choosing the correct hydroprocessing catalyst for specific applications within refineries.
1. The Feedstock Requirements and the Product Requirements
The feedstock and final product are important factors to consider when selecting the right hydroprocessing catalyst. Different catalysts are tailored for different reactions, such as hydrotreating, hydrocracking, hydrogenation, or hydrodenitrogenation. The catalyst chosen should be in line with desired output quality as well as the characteristics of the feedstock.
2. Catalyst Selectivity Activity
Catalyst activity and selectivity play a crucial role in selecting the right catalyst. In terms of catalyst efficiency, the activity will determine the effectiveness with which the catalyst can promote the desired reactions. Selecitivity on the other hand ensures unwanted side-reactions are minimised. Achieving the best product quality requires a balance of these two variables.
3. Compatible with the Process Conditions
Priority should be given to the compatibility between the chosen catalyst and process conditions. Temperature, pressure, composition of the feedstock and reactor type are all factors to consider. To maximize the efficiency of your process, you need to use a catalyser that is able to operate at specified temperatures and pressures.
4. Catalyst regeneration and longevity
It is possible to reduce operational costs by regenerating and reusing a catalyst. Reusable catalysts, and those with longer lives spans can offer significant economic benefits. After carefully weighing up the costs, it is best to choose between new and regenerated catalysers.
5. Environmental Concerns
For refineries, meeting stringent environmental regulations has become a major concern. In order to meet emission regulations and environmental goals, the choice of hydroprocessing catalyst should match. It is crucial to comply with environmental standards by using catalysts for the production low-sulfur, low-nitrogen fuels.
6. Cost and Economical Viability
The cost of the catalyst should not be a deciding factor. The total cost of ownership, which includes purchase, regeneration costs and operating costs, must be evaluated comprehensively. Selecting a catalyser should take into account the long-term cost-effectiveness as well as its economic viability.
