Abstract
Methods and compositions for stabilization and subsequent hydrogenation of a microbial-derived immiscible olefin are described. The methods comprise separating immiscible olefin from a mixture comprising an aqueous solution, microbial cells and immiscible olefin thereby forming a crude olefin composition; purifying the crude olefin composition thereby forming a purified olefin composition; and adding a phenolic antioxidant to the purified olefin composition wherein the phenolic antioxidant is a phenol derivative containing an unfused phenyl ring with one or more hydroxyl substituents. The methods further comprise reacting the purified olefin composition with hydrogen in the presence of a hydrogen catalyst such that hydrogen saturates at least one double bond in the olefin. Hydrogenated compositions produced by the methods are further provided.
