Abstract
There is provided an improved electrically heatable catalytic converter formed of an electrically heatable corrugated thin metal monolith and having a collimator axially spaced upstream of the electrically heatable monolith, said collimator having the purpose of straightening and subdividing the gas flow to minimize the tendency of the leading edges of the corrugated thin metal monolith to be folded over in use.
