Request a sales quoteAliphatic Alkylation in Petroleum Refining provides a fundamental understanding on the alkylation process, from molecular-level interfacial properties to macroscopic industry plants. Since the direct distillation of oil fractions does not satisfy the whole demand for fuel feedstocks, processes such as reforming, isomerization, and alkylation are needed to fulfill the market requirements within the gasoline pool. From the processes mentioned above, this book covers one of the most important refining processes due to the high quality of the alkylate with high research octane number (RON).
Although the Aliphatic alkylation with H2SO4 and HF as catalysts have been industrialized for many years, there still exists lots of problems due to the complex heterogeneous reaction, such as the thermodynamics, reaction mechanism, molecular-level interfacial properties, and so on.
- Introduces industrial alkylation technology and process safety with different catalysts
- Highlights reaction mechanisms and kinetic models using different catalysts
- Presents interfacial behaviors between reactants and catalysts that are fundamental in the process intensification of Aliphatic alkylation
Chemists and chemical engineers interested in industrial Aliphatic alkylation, its process optimization and intensification
