Liquid Collection<br />

Primary pyrolysis products are vapors and<br />

aerosols from decomposition of cellulose,<br />

hemicellulose and lignin.<br />

Liquid collection requires cooling and<br />

agglomeration or coalescence of aerosols.<br />

Simple heat exchange can cause<br />

preferential deposition of heavier fractions<br />

leading <strong>to</strong> blockage.<br />

Quenching in product liquid or immiscible<br />

hydrocarbon followed by electrostatic<br />

precipitation is preferred method.
