NOVELTY - Method for increasing flash point of starting liquid involves supplying starting liquid to component (A), heating the component (A) at 20-200 degrees C, and obtaining a processed liquid product, in which the processed liquid has increased flash point and reduced concentration of volatile components than the starting liquid, and a volatile components product.    USE - Method for increasing flash point of starting liquid produced by thermal conversion e.g. pyrolysis of petroleum materials and biomass e.g. wood, wood residue and agricultural residue for producing chemical or fuel e.g. biofuel, ethanol, methanol, biodiesel, and hydrogen fuel.    ADVANTAGE - The method enables effective and selective reduction of volatile components of starting liquid produced by thermal conversion of biomass and petroleum materials. Along with controlled amount of devolatilized organic chemicals, water can also be removed by operating the systems under deeper vacuum or slightly higher operating temperature.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) system (100) for thermal conversion, which consists of a feed system (105), a reactor (110), and condensing chambers (120,130) which are maintained at more than 30 degrees C; and    (2) method of processing, which involves introducing a devolatilized liquid material into a fluidized catalytic cracker, in which the devolatilized liquid material is produced by thermally converting biomass and/or petroleum materials, forming starting liquid, supplying the starting liquid to component (A), heating the component (A) at 20-200 degrees C, obtaining a devolatilized liquid material which has an elevated flash point temperature and reduced concentration of volatile components with respect to starting liquid, and obtaining volatile components product.    DESCRIPTION OF DRAWING(S) - The drawing shows schematic view of thermal conversion unit to produce primary liquids.
