Abstract
An alkane/fluoroalkane feed is treated with an acidic alumina to reduce the amount of fluoroalkane(s) in the feed. In a particularly preferred embodiment, the feed is treated with a sulfur-containing alumina so as to convert a major portion of fluoroalkane(s) to higher alkane(s).
Claims13
A process for removing fluoroalkanes from alkane streams which comprises contacting a feed stream comprising at least one feed alkane containing 3-10 carbon atoms per molecule and at least one fluoroalkane containing 3-10 carbon atoms and 1-2 fluorine atoms with a sulfur-containing alumina, which contains at least about 0.1 weight-% sulfur, at effective contacting conditions so as to convert a major portion of said at least one fluoroalkane to at least one product alkane having a higher number of carbon atoms than said at least one fluoroalkane.
