Abstract
The prospects of using catalysts based on metal cell-body and complex-oxide active coatings for purification of waste gases in various industries and transportation have been shown. Effective thermocatalytic neutralizers of harmful substances of chemical productions, for example, for afterburning of acrylonitrile, cresol and other organic compounds, have been created and successfully tested. Neutralizers of exhausts of diesel and Otto engines running on liquid transport and gas fuel have been developed and tested. The catalysts significantly reduce the content of carbon monoxide, fuel soot, nitrogen oxides in the exhausts. The search for new catalytic compositions and improvement of their manufacturing technology is underway. A new efficient absorption dryer for natural gas was created. This was done to ensure uninterrupted operation of transportation using environmentally less hazardous gas fuel during the winter period.
