You should know that raw petroleum is separated by distillation into LPG (liquid petroleum gas), gasoline-naphtha, kerosene, gas oil, heavy oil and residual oil. Among them, gasoline as a fuel of cars and naphtha as a raw material of plastic, fiber and ink are very useful. These distillates (C₅～C₁₀ hydrocarbons) support human society.

Diesel engines utilize gas oil, and therefore trucks, diesel trains, ships and generators utilize gas oil co-produced with gasoline. Even if you want to say "I never use cars. I keep my life only with agriculture and fishing.", fisherman's boat and tractors are fueled with gasoline and gas oil.

Gasoline has a huge demand. Practically, all of petroleum products are produced until gasoline is produced until the demand is satisfied, and usage of the co-produced other products is being found until they have been consumed. Therefore, the most important thing is the gasoline production.

Main component of crude oil is heavy and residual oil distillates (components which will be distilled into heavy and residual oil), consisting of large molecules. Therefore, cracking of petroleum into gasoline-naphtha over a zeolite catalyst with Brønsted acid sites are being carried out. In other words, the raw materials of gasoline, plastic and fiber are being produced using the zeolite catalyst. Your life is being supported by catalysts.
