Abstract
Processes for producing high-octane-number fuel components, particularly those useful for AvGas blends, can be advantageously produced from hydrocarbon feed streams comprising C8+ aromatic hydrocarbons. Such feed streams may be produced by, among others, separation and other optional post-processing of an effluent produced from a steam cracker (e.g., a liquid feed steam cracker cracking liquid feeds such as naphtha and/or other crude fractions, a gas steam cracker cracking gas feeds such as ethane and/or propane), hydrocarbon reforming of a crude fraction or steam cracker effluent fraction, C6-C7 aromatic hydrocarbon methylation, transalkylation between C6-C7 aromatic hydrocarbons and C9+ aromatic hydrocarbons, isomerization of C8 aromatic hydrocarbons, and toluene disproportionation processes.
