NOVELTY - A biomass solution comprises pretreatment solution having at least one working fluid selected from liquid ionic phosphates, polyammonium ionic liquid sulfonamides and/or poly(ionic liquids); or working fluid component (A1) from a biomass to biofuel conversion process; or a protein fraction preferably hydrolyzed into branched chain amino acids and peptides.    USE - For synthesizing biomass fuels from feedstock e.g. distiller's dried grain with solubles, corn, switchgrass, oat and rice (claimed).    ADVANTAGE - The biomass solution enables high energy efficiency conversion and transformation to alternative fuels including biofuels, which helps for reducing global warming gases. The microchannel heat exchangers and microchannel reactors used in the process increases the efficiency and performance of the system by extensive heat recovery.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a biomass pretreatment process using absorption heat pump having at least one working fluid component in fluid communication with the pretreatment process, involving either hydrolysis process terminated in a rapid expansion step carried out in an energy extraction device or a microchannel device having channels less than 10 microns for reducing precipitated cellulose; or rapid expansion pretreatment process having an expanded gas and a power generating thermodynamic cycle where the expanded gas from the pretreatment process is in fluid communication with a condenser of the power generating thermodynamic cycle as a means of increasing the thermodynamic cycle efficiency of both the biomass pretreatment process and the power generating thermodynamic cycle; or at least one step selected from electrochemical, electrolysis, electrocatalytic, and photocatalytic process step. The working fluid component is either the absorption heat pump refrigerant or refrigerant absorbent. The working fluid increases the biomass surface area in the pretreatment process. The energy extraction device includes gerotor, pressure exchanger, and quasiturbine.
