In the complex world of oil and gas refining, catalysts play a crucial role, acting as the unsung heroes behind many vital processes. While not directly involved in the reactions themselves, catalysts significantly accelerate and enable the transformation of crude oil into valuable products like gasoline, diesel, and plastics.
What is a Catalyst?
Simply put, a catalyst is a substance that speeds up a chemical reaction without being consumed in the process. It acts as a facilitator, providing an alternative pathway for the reaction to occur, lowering the activation energy required for the reaction to start.

Task: Imagine you are a refinery engineer tasked with choosing a catalyst for a new hydrocracking unit. You need a catalyst that:
Explain your reasoning for choosing a specific type of catalyst based on its properties.
Example:
You might choose a zeolite-based catalyst because:
This is a good exercise to help students understand the application of catalyst properties in a real-world scenario. Students should explain their reasoning for choosing a catalyst with high activity, selectivity, and stability. They should also mention specific catalyst types and their advantages based on the provided context. For example, they might choose zeolite-based catalysts, metal-supported catalysts, or bifunctional catalysts and justify their choice with the properties of the specific catalyst type. The answer should be based on the specific requirements of the task and demonstrate understanding of the principles discussed in the text.
