TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The step of (d) is carried out via a liquid-vapor contacting unit in the absorption and quenches apparatus. The temperature of the biomass pyrolysis effluent stream is at least 300 degrees F (149 degrees C). The temperature of the cold quench fluid feed is less than 850 degrees F (454 degrees C). The step of (b) is carried out via a separation apparatus (25) comprising cyclone, wash column and/or absorption column. Preferred Components: The cold quench fluid is a solvent comprising hydrocarbon solvents and/or substituted hydrocarbon solvents. The separable component is derived from the wet pyrolysis oil or the char. The separable component is absorbed and/or dissolved in the solvent under a solvent-to-wet-pyrolysis-oil ratio equal to or greater than 1:1, where more than 50% of the separable components separate outside the solvent phase. The solvent to the wet-pyrolysis-oil is 1:100-100:1, preferably 1:2-20:1. The separable component is furans, substituted furans, anhydrosugars, phenolic compounds, polyphenolic compounds, carboxylic acids, carboxylates, substituted carboxylic acids, aldehydes, ketones, substituted aldehydes or ketones, alcohols, polyols, substituted alcohols or polyols, water, char, chemical and/or physical. The cold quench fluid feed is a thermally stable aromatic solvent comprising at least 30%, preferably less than or equal to 30% aromatic carbon. The aromatic solvent is aromatic extracts from solvent extraction of vacuum distillates, and its sub-fraction. The aromatic solvent is a cracked refinery stock comprising heavy cycle oils, heavy coker gas oils, heavy visbreaking distillates, heavy thermal cracking distillates and/or clarified catalytic cracking decant oils, and its sub-fraction. The aliphatic solvent is one or more extracts from solvent extraction of vacuum residues. The aliphatic solvent is refinery stock comprising vacuum gas oil, intermediate and heavy vacuum distillates, naphthenic oils, heavy hydrocracker distillates, and/or heavy distillates from hydroprocessing, and its sub-fraction.
