TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The method (m1) further involves rupturing lignocellulose in the biomass to produce ruptured biomass including the inorganic material, and the rupturing is performed before washing the biomass; it further involves air drying the inorganic-material-depleted biomass, performed before pyrolyzing step. The drying is performed at 20-50 degrees C. The method (m1) further involves conveying the carbon dioxide produced from the pyrolyzing for the drying. The rupturing is carried out by crushing or chopping the lignocellulose in the biomass. The solvent is maintained at 10-90 (preferably 50) degrees C. The washing includes washing ruptured biomass using recycled solvent. The recycled solvent is maintained at 30-70 (preferably 50) degrees C. The pyrolyzing is carried out at 200-400 (preferably 200-350) degrees C in the absence of oxygen. The pyrolyzing is carried out for 10 minutes to 24 hours. The method (m1) further involves densifying the combustible biomaterial to produce biocoal; soaking the ruptured biomass in the solvent before the washing the ruptured the biomass; pressing the inorganic-material-depleted ruptured biomass to squeeze out the residual solvent after the washing the ruptured biomass; and drying the inorganic-material-depleted ruptured biomass after the screw pressing. The densifying is carried out using a pelletizer to produce biocoal pellets. The soaking is carried out at 30-70 degrees C. The soaking is carried for 5-90 minutes. The solvent has a pH that is 4-7. The drying involves air drying the inorganic-material-depleted ruptured biomass or drying the inorganic-material-depleted ruptured biomass using syngas produced from the pyrolyzing, and where the syngas includes one member selected from alcohols, aldehydes, carboxylic acids, carbon dioxide, carbon monoxide, methane, butane, propane, and hydrogen. The method (m2) further involves washing a third discrete amount of biomass with the second effluent stream to produce a third effluent stream where the third effluent stream has a higher concentration of inorganic material than the second effluent stream; washing the second discrete amount of biomass with the solvent after the washing the first discrete amount of biomass with the solvent; and washing different discrete amounts of biomass ranging from a first discrete amount of biomass to an N discrete amounts of biomass, washing the Nth discrete amount of biomass with an (N-1)th effluent stream, which results from washing (N-1) discrete amounts of biomass, where N is a whole number that is greater than 2. Washing the Nth discrete amount of biomass produces an Nth effluent stream which has a higher concentration of inorganic material than the (N-1) effluent stream. The Nth effluent stream is recycled back as solvent for washing another discrete amount of biomass or is conveyed for effluent treatment. The method (m2) further involves collecting the first effluent stream in a first collection chamber after the washing the first discrete amount of biomass; pumping the first effluent stream to a position from where the first effluent stream can be dispensed to wash the second discrete amount of biomass; collecting the second effluent stream in a second collection chamber after the washing the second discrete amount of biomass; pumping the second effluent stream to a position from where the second effluent stream can be dispensed to wash a third discrete amount of biomass; unloading the first discrete amount of biomass after the washing the first discrete amount of biomass with the solvent; and advancing the second discrete amount of biomass to a position from where the washing of the second discrete amount of biomass is carried out, and the advancing is performed after the washing the first discrete amount of biomass. The method (m3) further involves conducting an Xth washing cycle, which includes washing an Xth of N discrete amounts of biomass using a solvent to produce a first effluent stream associated with the Xth washing cycle, washing an (X+1)th of N discrete amounts of biomass using the first effluent stream associated with the Xth washing cycle to produce a second effluent stream associated with the Xth washing cycle and washing other discrete amounts of biomass to satisfy a condition of washing the Nth discrete amount of biomass using an (N-X)th effluent stream associated with the Xth washing cycle, where the X is a whole number ranging from 3 to the N. Each of the N discrete amounts of biomass is washed with the solvent. The washing the first discrete amount of biomass is carried out by spraying the solvent on the first discrete amount of biomass. The washing the N discrete amount of biomass includes washing a total of the biomass which weighs 1-1000 metric tons. The N discrete amount of biomass is washed with 1000 liters and about 40 mega-liters of solvent. Each of the N discrete amounts of biomass weighs 1 kg and about 100 metric tons. Each of the N discrete amounts of biomass is washed with 't' volume of solvent i.e. 0.5 l to 4 mega-liters. The washing the first discrete amount of biomass occurs for 5-90 minutes. The solvent is maintained at 10-90 (preferably 20-70) degrees C. The first effluent stream associated with the first washing cycle is maintained at 10-90 (preferably 50) degrees C. The method (m3) further involves draining the first effluent stream associated with the first washing cycle into a first collection chamber; pumping the first effluent stream associated with the first washing cycle such that it is dispensed above the second of the N discrete amount of biomass to produce the second effluent stream associated with the first washing cycle; collecting the second effluent stream into a second collection chamber; emptying the first bin after washing the first discrete amount of biomass with the solvent; after the first washing cycle is complete, advancing the second bin to a position so that the second bin can undergo washing using the solvent during the second washing cycle; after the first washing cycle is complete, displacing a spray configured to dispense the solvent to a position such that the solvent is sprayed above the second of the N discrete amounts of biomass; after a single washing cycle of one discrete amount of biomass contained inside one bin is complete, displacing a spray configured to dispense the solvent to position such that the solvent is sprayed above another discrete amount of biomass, which is not previously washed; heating the second effluent stream after the washing the second discrete amount of biomass; and sieving the first effluent stream before the washing the second discrete amount of biomass.
