Biomass -8, Wood Ethanol: Enzyme & Acid Hydrolysis
• -->cont: • :
• Forest Residual: Cellulosic Ethanol, & other Fuels: There are many
combos but main types are: -Enzymatic Hydrolysis based, some
pretreatments include classic sulfuric acid, alkaline to low cost
Sub/Supercritical water etc:(Chempolis, St1 biofuels, Sekab, Mitsui Zosen -
, dins +),(also see Agri left over p111-113)
-Acid Hydrolysis based,: Fundamentally different business model compared
to all other main biofuel technologies. Sulfuric Ethanol is around 100yrs+
as major byproduct of Sulfite Pulping(Borregaard+) which is now mostly
phased out by Kraft Pulp.
High temperature Dilute Acid Hydrolysis Ethanol production(0.2-5% range
H2SO4), this simple continuation of supposed to be “good only for
pretreatment” process is ignored by most of modern west(Kirov Ethanol+):
wood boiling/distilling with “semi” SubCritical water element. Its operation
mode is rather more like some pulp-paper mill like business model(eg
Rayonier-Tembec Temiscaming+) than low value fuel making. -->cont:
