Thermal cracking is a refinery process that breaks larger hydrocarbon molecules into smaller molecules like gasoline. The presentation discusses various aspects of thermal cracking including: 1. The necessity of cracking to produce more gasoline from heavier crude oil fractions. 2. The main types of cracking - thermal cracking and catalytic cracking. Thermal cracking uses high temperatures without a catalyst. 3. Key thermal cracking processes like Dubbs, pyrolysis, visbreaking, and coking which use different temperatures and pressures to produce different product yields. 4. The thermal cracking reactions of decomposition, hydrogenation, polymerization, and cyclization that alter the hydrocarbon molecules. 5. Commercial thermal cracking units and how they operate to continuouslyRead less
