Methane in Air Quality and Automobile Exhaust Emission Standards

Monolithic Three-way Palladium Catalytic Converters for Automobile Exhaust Emission Control

This article presents the research results on production and performance of palladium-only catalytic converters. Monolith is used as the catalyst carrier and gamma alumina as the substrate. Dipping method is used for monolith washcoating. Palladium as the active metal is impregnated on gamma alumina using wet impregnation to produce catalyst samples. The effects of factors such as percent solid...

Study of Air Pollution Due to Automobile Emission in Ooty

Ooty the Head Quarters of Nilgiris Districts has a large Number of commercial and non-commercial vehicles, due to increasing industrialization and Tourism related activities. In this thesis a study was conducted on vehicle pollution in Ooty town to asses pollution contribution from transport sector. Pollution due to auto exhaust has assumed menacing proportion in the developing countries like I...

Method for determining H2SO4 in automobile exhaust.

A relatively simple procedure for measuring H2SO4 in auto exhaust will be presented. The system is compatible with the Federal constant volume sampler (CVS unit). The time required to get sufficient sample for titration is 15-30 min. Values on sulfates in exhaust with a catalyst car and a noncatalyst car agree well with literature data obtained by dilution tube and filtration techniques.
