TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Method: The method (I) further comprises: recovering the first renewable fuel; contacting the second volatile component with a gas-upgrading catalyst (62) to produce a second product which on cooling to a temperature of 1-20 degrees C produces a third volatile component, a second renewable fuel and water; recovering the second renewable fuel; and subjecting the third volatile component to at least one of processing station, dehydration catalyst, aromatization catalyst, gas-upgrading catalyst or combustion gas treatment plant. The method (II) further comprises: recovering the first renewable fuel; contacting the second volatile component with a gas-upgrading catalyst to produce second product which on cooling to a temperature of 0-5 degrees C produces a third volatile component, second renewable fuel and water; recovering the second renewable fuel; routing the third volatile component to the processing stations, dehydration catalyst, aromatization catalyst, gas-upgrading catalyst or combustion gas treatment plant. The method (III) further comprises: recovering the first renewable fuel; contacting the second volatile component with aromatization catalyst to produce second product which on cooling to temperature of 0-5 degrees C produces third volatile component, second renewable fuel and water; recovering the second renewable fuel; contacting the third volatile component with gas-upgrading catalyst to produce third product which on cooling to temperature of 0-5 degrees C produces a fourth volatile component, third renewable fuel and water; recovering the third renewable fuel; and subjecting the fourth volatile component to the processing stations, dehydration catalyst, aromatization catalyst, gas-upgrading catalyst or combustion gas treatment plant. EXAMPLE - Biomass (150 g) comprising commercial sunflower seeds along with dimethyl ether as co-solvent were devolatilized starting at a temperature of 325 degrees C and ending at 575 degrees C with a temperature increment of 50 degrees C for every hour. Methanol (131 g) was passed through a silica alumina catalyst to generate the required co-solvent. The output was passed through three different catalyst columns in series including dehydration catalyst, aromatization catalyst and gas-upgrading catalyst. The fuel was collected at each temperature for each catalyst at half-hour intervals.
