Methane is the most destructive Green-house gas and a promising feedstock capable of producing high value-added products through conversion reactions such as gas-to-liquids (GTL). However, in typical conversion reaction, chemical GTL, harsh condition is essential to activate C-H bond of methane and this process is energy intensive. In contrast to chemical reaction, Bio-GTL using methanotroph recently has been attracted attention because it can be carried out in mild condition. Still, Bio-GTL has several drawbacks, including poor productivity of methanol due to product inhibition and mass transfer problems by differences in solubility of reactants. In this research, we introduce two phase membrane-CSTR to bio-GTL. With CSTR, we could easily remove produced methanol that causes product inhibition and by using cellulose membrane and methane vector as oil phase, we could not only trap methanotroph but also increase mass transfer efficiency by mixing and lower differences in solubility. |
