Pretreatment usually results in a considerable mass loss of plant biomass components, depending on the type of pretreatment method, the applied experimental conditions, and the type of
biomass used for conversion As shown in Tables 1 and 2, the pretreatment severity influenced the percent- age of mass loss. Likewise, higher losses were observed when different pretreatment residence times were compared at the same temperature. As a result, the mildest pretreatment condition of
180 C for 6 min had the lowest mass loss and the results at more
