NOVELTY - A processor comprises a material densifier optionally including a preheater for preheating biomass material, and a microwave unit for conducting microwave-assisted torrefaction of biomass material. The microwave unit comprises a material transfer feed pipe provided with gas and/or liquid outlets to enable rapid removal of gas and/or liquid formed during the process.    USE - Processor for use in microwave torrefaction of biomass material such as lignocellulosic material, cellulose, hemicellulose, or lignin (claimed).    ADVANTAGE - The processor allows for energy efficient biomass processing by using microwave technology, provides high yield of pyrolysis oil at low temperature (less than 300 degrees C), and produces high calorific value char (from biomass) having physical properties suitable for direct use in energy production at low temperature.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a process for microwave torrefaction of biomass material such as lignocellulosic material, including densifying biomass material, optionally preheating, torrefying the material in microwave processor, and collecting gas and/or liquid formed during the process;    (2) a micronized biomass char material;    (3) a method of producing micronized biomass char material, by microwave torrefaction of biomass material and micronizing;    (4) a method of producing L-glucosan by microwave torrefaction of biomass material in the presence of ammonia ( less than or equal to 5 wt.%) or hydrochloric acid ( less than or equal to 30 wt.%), in which the L-glucosan comprises 40-80 wt.% biomass;    (5) a process of manufacturing glucose by microwave torrefaction of biomass material in the presence of ammonia or protic acid to produce L-glucosan, and digestion of L-glucosan;    (6) a method of producing biochar by microwave torrefaction of biomass material in the presence of sulfuric acid ( less than or equal to 5 wt.%) or hydrochloric acid;    (7) a method of producing biowax by microwave torrefaction of biomass material in the presence of trialkylamine;    (8) a fuel comprising micronized lignocellulosic char material or biochar material; and    (9) an oil, preferably secondary oil, derived from microwave torrefied biomass.
