The French company Global Bioenergies announced having purified bio-isobutene to a level of 99.77 %.
Evry/France – Global Bioenergies produces isobutene batches at its industrial pilot plant located in Pomacle-Bazancourt, eastern France. Up to now, 95 % purity was reached, a level sufficient for several applications, such as fuels and paints.
With the assistance of Processium, a chemical engineering company headquartered in Lyon, France, Global Bioenergies was able to purify batches to a much higher level, reaching 99.77 %, the remaining 0.23 % being mostly composed of CO2, an inert gas known to be neutral in most chemical reactions.
Thomas Buhl, Head of business development at Global Bioenergies, comments: "Several applications in the polymers business (rubbers, plastics.) require high-purity isobutene, and 99.77 % corresponds to the polymer-grade standard. We expect that our high-purity bio-isobutene will meet the specifications of the industrial leaders involved in converting isobutene into polymers, and that they will be able to use their existing polymerization processes, designed for fossil feedstocks, without any significant change. The higher the purity, the higher the value: targeting higher-value markets is especially important in the present oil and gas environment."
