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 to form 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. 一种用于生产燃料添加剂的方法，包括：使包含粗混合的C4烃的烃流穿过第一氢化单元，以生产第一产物流；将第一产物流从第一氢化单元传递到甲基叔丁基醚合
