Abstract:
Processes for increasing a virucidal activity of a fiber substrate are disclosed. A fiber substrate comprising borosilicate is provided. The fiber substrate may comprise acidic functional groups. An antiviral metal salt solution is introduced to the fiber substrate to form an antiviral substrate. The pH of the antiviral metal salt solution is adjusted, and an antiviral metal ion is exchanged with a proton from the acidic functional groups. The antiviral metal is present in an amount ranging from about 0.001 to about 3.0 wt. % of the antiviral fiber substrate. The antiviral fiber substrate is incorporated into a filter media before or after the deposition of the antiviral metal onto the fiber substrate.

Abstract:
An alkylation process is described. The alkylation process includes contacting a feed comprising a paraffin or an aromatic with an olefin feed in the presence of a liquid Lewis acid catalyst in an alkylation reaction zone under alkylation conditions to form a reaction mixture comprising alkylation products and the liquid Lewis acid catalyst. The liquid Lewis acid catalyst is the liquid reaction product of a donor molecule and a metal halide. The alkylation products are separated from the liquid Lewis acid catalyst and recovered.

Abstract:
A method of regenerating an acidic catalyst is described. A borane compound is contacted with an acidic catalyst that contains conjunct polymer, which releases the conjunct polymer from the acidic catalyst. The acidic catalyst can then be re-activated with acid. The conjunct polymer can be separated from the borane compound, and the borane compound can be recycled.
