Abstract
Methods are disclosed for converting propane and higher alkanes to their corresponding alcohols through a multi-step process with olefin as an intermediate. Methods are also disclosed for facilitating the transportation, purification or other treatment of propylene and higher olefins using a chemical conversion to the corresponding alcohol and reconversion to olefin. Methods are also disclosed for converting propane and higher alkanes to olefins using the corresponding alcohol as a temporary intermediate to minimize purification, transportation and/or other treatment costs.
Claims10
A method for the production of alcohols having three or more carbon atoms from corresponding alkanes comprising:
- a) converting at least a portion of a reactant stream comprising propane and/or one or more longer-chain alkanes to an intermediate product stream comprising one or more corresponding olefins through a catalytic oxidative dehydrogenation reaction;
- and
- b) converting at least a portion of the intermediate product stream comprising one or more corresponding olefins to a product stream comprising one or more corresponding alcohols through an indirect catalytic hydration reaction.
A method for the sequential hydration of two or more alcohols from two or more corresponding alkanes comprising:
- a) converting a reactant stream comprising two or more alkanes to an intermediate product stream comprising olefins;
- and
- b) converting one or more olefins in the intermediate product stream comprising olefins to a first product stream comprising one or more alcohols under selective hydration conditions with respect to one or more other olefins in the intermediate product stream comprising olefins through an indirect catalytic hydration reaction.
