Synergistic effect of Brønsted acid and platinum on purification of automobile exhaust gases
The catalytic purification of automobile exhaust gases (CO, NOx and hydrocarbons) is one of the most practiced conversion processes used to lower the emissions and to reduce the air pollution. Nevertheless, the good performance of exhaust gas purification catalysts often requires the high consumption of noble metals such as platinum. Here we report that the Brønsted acid sites on the external s...
متن کاملMethod 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.
متن کاملPhysiological changes in certain test plants under automobile exhaust pollution.
Plants are the only living organisms which have to suffer a lot from automobile exhaust pollution because they remain static at their habitat. But such roadside plants like Nerium indicum Mill., Boerhaavia diffusa L., Amaranthus spinosus L., Cephalandra indica Naud., and Tabemaemontana divaricata L. can easily avoid the effects of air pollution by altering their physiological pathways pertainin...
متن کاملNon-thermal Plasma Treatment of Automotive Exhaust Gases
Treatment of NOx in diesel engine exhaust represents a big opportunity for the environmental application of low-temperature plasmas. In this paper NOx conversion to N2 was investigated by Plasma/Catalyst System Catalytic activity was enhanced by the assistance of plasma ,and the plasma/Catalyst system showed higher NOx conversion. It is shown that the plasma by itself cannot chemically reduce N...
متن کاملOptions for Abating Greenhouse Gases from Exhaust Streams
This report examines different alternatives for replacing, treating, and recycling greenhouse gases. It is concluded that treatment (abatement) is the only viable short-term option. Three options for abatement that were tested for use in semiconductor facilities are reviewed, and their performance and costs compared. This study shows that effective abatement options are available to the photovo...
