Lignocellulose biomass is heterogeneous in nature have different ratios of xylans and cellulose sugars , and requires processing to closely homogeneous fractions and consistency for its application in the production of variety of fuels and biochemical. The breakdown of biomass is a key first step in the conversion of cellulosic sugars ,and this process has posed the great challenge to the economically viability of recovering sugars and its application for fuels and biochemicals.
This presentation will review Sweetwater Energy’s overall process of optimizing dilute acid pretreatment conditions of various heterogeneous biomass feedstocks . Importance of optimizing and methods of pretreatment conditions [time , temperature , pressure and particle size ] will be reviewed. Intent is to generate homogeneous, uniformly exploded and cooked, consistent particle size post treatment. Deriving a uniformly sized pretreated feedstock enabled and improved enzyme saccharification yields . In addition, specific challenges in controlling inhibitors sugar syrup will be discussed in details . Finally in technology scale up and accelerating the path to process commercialization and finally direct applications of SWE sugars in ethanol , biochemical and advanced fuels, will be reviewed .
