The present application provides systems and methods for producing isononanol and gasoline and diesel blending components. In at least one embodiment of the present systems and methods, a hydrocarbon feed is cracked in a steam cracker to form a first ethylene stream, a first propylene stream, and a C4 stream comprising isobutene and butadiene. The C4 stream is reacted with a methanol stream in a methyl tertiary butyl ether (MTBE) unit to form MTBE and a butadiene-rich C4 stream. The butadiene-rich C4 stream is selectively hydrogenated in a butadiene unit to form a butene-rich C4 stream. The butene-rich C4 stream undergoes a series of reactions in an isononanol unit to produce isononanol and an olefin-rich stream. The olefin-rich stream is then separate, in a separation unit, a C8, C12, and C16 fuel oil streams.
