In order to improve engine performance by reducing hydrocarbon (HC) emissions from cold
start of gasoline engine, firstly, cold-start emission control measures such as pre-treatment …

Efficient separation of xenon (Xe) and krypton (Kr) mixtures through vacuum swing
adsorption (VSA) is considered the most attractive route to reduce energy consumption, but …

With the global emphasis on environmental protection and increasingly stringent emission
regulations for internal combustion engines, there is an urgent need to overcome the …

In this paper, a hydrocarbon (HC) adsorber and converter (HCAC) system is proposed for
hydrocarbon emission control during cold start (Hydrocarbons are adsorbed in HC adsorber …

To reduce pollutant emission of gasoline engine during cold start, ZSM-5 zeolite was
selected as adsorbent and coated on cordierite carrier and encapsulated as a hydrocarbon …

Catalytic oxidation of methane (CH4) over nonprecious Ni/CeO2 catalysts has received a lot
of attention due to the large natural gas reserves found in North America and the prohibitive …

The feasibility of ZSM-5 zeolite for controlling hydrocarbon (HC) emissions during cold start
period of gasoline engine was studied by temperature programmed desorption (TPD) …

Interest in Pd/zeolites as automobile exhaust catalysts has driven research focused on
understanding the chemical environment of Pd active centers. Here, we studied the effects of …

The abatement of harmful nitrogen oxides (NO x) emission during vehicle cold start is
challenging. Passive NO x adsorbers (PNAs) have proven to effectively alleviate NO x …

The C 2 H 4 adsorption and desorption properties of palladium-impregnated zeolites with
different pore systems (ie, Pd-beta, Pd-ZSM-5, and Pd-SSZ-13) but similar Si/Al ratios (13 …
