    2,3-Butanediol Separations

    Background and Goals 2,3-butanediol (BDO) is gaining attention in the global market as an intermediate product for several applications, such as liquid fuel or as a fuel additive. It can be produced through fermentation in low concentrations (<10 wt%). Therefore, BDO separation/concentration is required for … Read More
