Abstract

Production of lower-molecular-weight hydrocarbons from higher-molecular-weight hydrocarbonaceous material by heating at an elevated temperature in the presences of a guanidinium compound such as guanidinium carbonate, oleate, palmitate stearate or phenolate. The invention is especially applicable to coal liquefaction and gasification.
