  • Ethanol Production Process an overview

    The ethanol production process consists of four main stages: Pretreatment: The lignocellulosic material, which mainly consists of cellulose hemicellulose and lignin, is treated with dilute acid at high temperatures and pressure to degrade the lignin and to convert the hemicellulose into xylose and by-products (e.g furfural, HMF and organic acids) ( Esteghlalian et al., 1997 ; Nigam et al., 2011 ).
