TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Process: The process further comprises catalyst comprising chromium, lanthanum, aluminum, copper, cobalt or sodium or catalyst comprising copper, cobalt, chromium or potassium.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: In the process, the step of providing the aqueous alcohol stream, comprises passing synthesis gas comprising hydrogen, carbon monoxide and carbon dioxide through catalytic zone. The step of removing the lower alcohols from the aqueous alcohol stream results in at least a 1:1.4 weight ratio of 3C to C4+ alcohols in the resultant aqueous alcohol stream. The step of removing the lower alcohols from the aqueous alcohol stream comprises: providing the aqueous alcohol stream to a distillation column; and removing isopropanol from the aqueous alcohol stream. The process further comprises: providing an overhead product stream including methanol, ethanol and water associated with the ethanol azeotrope from the distillation column to a second distillation column to separate the methanol; providing a bottoms product including C3+ alcohols and water from the distillation column to an extraction column; providing a solvent to the extraction column; operating the extraction column counter-currently; and distilling the extract exiting the top of the extraction column in a third distillation column to separate the C3+ higher alcohols from the solvent. In the process, energy generated from passing the synthesis gas through catalytic zone is used to provide energy to reboiler, second reboiler or third reboiler for driving the distillation column, second distillation column or third distillation column respectively. The energy from the overhead product stream from the distillation column is used to provide energy to a second reboiler for driving the second distillation column and no additional energy is required to drive the distillation column, the second distillation column and the third distillation column. Preferred Components: The solvent is gasoline. EXAMPLE - No suitable example given.
