Abstract: A method for the production of a fuel additive includes passing a hydrocarbon stream comprising crude mixed C4 hydrocarbons through a first hydrogenation unit to produce a first product stream; passing the first product stream from the first hydrogenation unit to a methyl tert-butyl ether synthesis unit forming methyl tert-butyl ether and a byproduct stream; passing the byproduct stream through a first distillation unit to separate the byproduct stream into a first 1-butene stream, an isobutane stream, and a 2-butene and n-butane stream; forming a second product stream by passing the 2-butene and n-butane stream to a selective conversion unit; passing the second product stream into a second distillation unit to form an n-butane stream and a second 1-butene stream; passing the second 1-butene stream to a fuel additive production unit; and passing the first 1-butene stream to the fuel additive production unit to form the fuel additive.

Abstract: A method of manufacturing a cetane-boosting fuel additive includes reacting formaldehyde and 2-ethylhexanol at a mole ratio of 10:1 to 1:1, or 5:1 to 1.5:1, or 4:1 to 2:1, or 3.5:1 to 2.5:1 in the presence of a heterogeneous acid catalyst at a temperature of 300 to 375° K to obtain a cetane-boosting product mixture comprising H3C(CH2)3CH(CH2CH3)CH2(OCH2)nOH, H3C(CH2)3CH(CH2CH3)CH2(OCH2)nOCH2CH(CH2CH3)(CH2)3CH3, or a combination thereof, wherein n has an average value of 2.8 to 3.2, preferably an average value of 3.
