Abstract
A solid catalyst, such as a molecular sieve catalyst or solid acid catalyst, is supported by a binder, such as amorphous silica or alumina, wherein the binder is charged with metal ions to form an ion-modified binder. The ion-modified binder is capable of attachment to polar contaminants and inhibit their contact with the catalyst. The catalyst can be a zeolite and can be the catalyst for an alkylation reaction, such as the alkylation of benzene with ethylene.
