(521db) Selective Hydropyrolysis-Prehydrotreating-Hydrotreating Process of Grasses to Produce Fuel Components. Nicepd/SiO2 Oxygen Effects in Diesel Emission

Biomaterials were selectively processed using inverted cyclone hydropyrolyisis [1] fluidized bed prehydrotratment [2] and fixed bed hydroprocessing pilot plant. Naphtha-diesel product containing naphthenic-aromatics polyoxygenated hydrocarbons, are stable compatible and reduce Diesel emissions due to oxygen scavenger activity.
