The invention provides methods and apparatus for thermal treatment, e.g. for pyrolysis of lignin. The lignin is provided to a reaction chamber as a paste, which can reduce or avoid process difficulties encountered when heating lignin.

in the presence of pyridine-2,6-dicarboxylic acid and PhI(OAc)(2) can efficiently catalyze the formation of chemoselective dialkyl acetals from styrene derivatives with anti-Markovnikovregioselectivity in good to high yields under mild and benign reaction conditions.
