TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The material susceptible to the absorption of electromagnetic radiation comprises a transition metal or a Rare-Earth. The transition metal is a non-noble transition metal selected from iron (Fe), magnesium (Mn), zinc (Zn), cooper (Cu) and/or nickel (Ni) (preferably Fe).    TECHNOLOGY FOCUS - POLYMERS - Preferred Process: The material susceptible to the absorption of electromagnetic radiation is introduced into the biomass by impregnating the biomass with a solution of a compound of the material. The solution is an aqueous solution. The biomass is of photosynthetic origin. The biomass comprises cellulose and/or ligno-cellulose. The step (a) involves genetically engineering a plant thus it incorporates the radiation susceptible material into its polymer structure, and producing biomass from the genetically engineered plant; and feeding plants with nutrients rich in radiation susceptible material thus the radiation susceptible material becomes incorporated into the polymer structure of the plants; and converting the plants to biomass material. The electro-magnetic radiation has a frequency in the microwave range (preferably 300 MHz to 300 GHz, preferably 1-100 GHz). The material susceptible to the absorption of electro-magnetic radiation comprises nanoparticles of a magnetic material. The magnetic material is a paramagnetic material, ferromagnetic material or superparamagnetic material (preferably iron oxide). The step (b) involves heating the biomass by subjecting the biomass to an AC magnetic field having a frequency of 1 kHz to 5 MHz. The activated biomass is subjected to liquefaction under mild conditions. The mild conditions comprise a temperature of 150-500 (preferably ambient temperature to 350)degrees C and a pressure of 1-50 (preferably 1-25) bar. The mild conditions comprise hydrothermal conversion conditions; mild pyrolysis conditions; hydrolysis conditions; hydro-conversion, hydro-cracking or hydro-treating conditions; catalytic cracking conditions; or enzymatic conversion conditions. Making (M2) bioliquid susceptible to depolymerization under mild conditions, involves: (a1) introducing a material susceptible to the absorption of electro-magnetic radiation into the bioliquid to form a radiation absorbent bioliquid; (b1) subjecting the radiation absorbent bioliquid to electro-magnetic radiation to form an activated bioliquid. The step (b1) involves a continuous process for converting radiation absorbent biomass to activated biomass including the step of conveying radiation absorbent biomass through a zone where electro-magnetic radiation is generated. The method (M2) involves additional step of converting the activated biomass into liquid and/or gaseous products. The electro-magnetic radiation of the radiation absorbent biomass and the conversion of the activated biomass are carried out in a one step process. EXAMPLE - A biomass material (White Pine wood chips) was initially pulverized with a mechanical mixer for 5 minutes to reduce the particle size to 5 mm. This wood material was wet milled (15 wt.% slurry based on the dry weight (150degrees C) of the wood) along with raw high iron-containing (Fe=40%) bauxite (bauxite to wood ratio of 5:100) in a planetary high energy mill (Pulverisette 6). The milled slurry was subjected to microwave radiation to activating the biomass material.
