  1. Question 1

    Q1. A refinery technician must choose between thermal cracking and catalytic cracking. Which outcome distinguishes catalytic cracking from the thermal process?

    • A) Catalytic cracking produces gasoline of higher octane number
    • B) Thermal cracking requires lower temperatures than catalytic
    • C) Catalytic cracking produces only gaseous alkanes
    • D) Thermal cracking utilizes silica and alumina as catalysts

    Answer: Catalytic cracking produces gasoline of higher octane number

    Explanation: Catalytic cracking yields higher quality gasoline with higher octane numbers, whereas thermal cracking primarily produces lower quality unsaturated hydrocarbons.
