New catalyst comprising silver deposited on aluminum oxide, and zinc oxide, useful e.g. in selective catalytic reduction reaction of nitrogen oxides by hydrocarbons and/or oxygenated compound

摘要

Catalyst comprising silver deposited on aluminum oxide, and zinc oxide, is new. Independent claims are included for: (1) catalytic conversion device, comprising the catalyst deposited on a monolith; and (2) vehicle comprising motor and an exhaust line connected to the motor outlet, where the catalyst or the catalytic conversion device is disposed on exhaust line.
