TWO-STAGE PROCESS FOR THE CONVERSION OF TAR SAND TO LIQUID FUELS AND SPECIALTY CHEMICALS

摘要

A process is disclosed for converting Tar Sand to fuels and/or valuable c hemicais. The process comprises the steps of a) activating Tar Sand to make it more susceptible to conversion; c) partially converting the Tar Sand to a solubilized material; and d) subjecting the unconverted Tar Sand to a secon d conversion step. The process optionally comprises a step b) of adding a so lvent to the activated Tar Sand. In a preferred embodiment the solubilized T ar Sand obtained in step c) is removed before the unconverted Tar Sand is su bjected to step d).
