“…Based on our previous research for establishing this system, measurements of the desulfurization breakthrough characteristics of CaCO 3 washcoated on the monolith acquired at 650 • C and 10 4 h −1 demonstrated that the necessary amount of CaCO 3 for running the diesel engine for 10 5 ∼2.1-2.2 L. In this paper, enhanced SO 2 -capture performance with lower temperature activation was developed to cope with the wide temperature region for diesel exhaust. Mixing a basic material with basic CaCO 3 is proposed as a technique for achieving the aforementioned goals.…”

4DENOSO Corporation, Kariya city, Aichi Prefecture, Japan NO x emitted from diesel engines is one of the major air pollutants in most countries. To reduce NO x emission, NO x storage/reduction (NSR) catalysts have been developed for diesel systems. The catalyst for NSR is strongly poisoned with sulfur. This paper reports the synthesis of Na-doped CaCO 3 as a new material for SO 2 adsorption. Measurements of the desulfurization breakthrough characteristics using monolith washcoated Na-doped CaCO 3 were investigated at 450 • C. The Na-doped CaCO 3 absorbed ∼77.6-90.6 mg -SO 2 /g -material of SO 2 at 450 • C (where CaCO 3 is 8 mg -SO 2 /g -material ). Investigation of the source of the improved sulfur absorption capacity of the Na-doped CaCO 3 relative to the parent material via x-ray diffraction (XRD) and scanning electron microscopy-energy-dispersive x-ray spectroscopy (SEM-EDX) analyses revealed that the new material forms a composite partially composed of Na 2 Ca(CO 3 ) 2 . The enhanced SO 2 absorption capacity derived from the formation of composite materials is demonstrated herein. SO 2 contained in the exhaust gas is absorbed at a lower temperature than with previously reported systems. In order to elucidate the SO 2 absorption mechanism of the composite materials, further studies and synthesis of materials with greater absorption capacity are required.

“…We also established that CaCO 3 reacts well with SO 2 at 650 • C [5]. Furthermore, the desulfurization characteristics of CaCO 3 under low SO 2 concentration and high space velocity conditions were evaluated [6].…”

In this study main purpose of the project is to reduce the pollution which is caused due to vehicles exhaust gas and ensure the environment pollution free. Aim to maximize the efficiency of emission control as compare to other Reduce the back pressure and increase the efficiency of an engine. Vehicle exhaust gases like carbon dioxide (CO2), hydrocarbon (HC) and carbon monoxide (CO) are highly toxic. These components are the major problem to environment and health. Therefore, our main concern is designing of packed column and analyze the dual absorbent system to reduce the toxic of emission of gases. In this study we are using a group of two absorbent named ZSM-5 and MORDENITE having catalyst PLATINUM materials with the ability to absorb CO2, carbon monoxide, NOx and HC which is coming out from the vehicular engine after the exhaust process. The dual absorbent was able to remove CO up to 88.04%, HC up to 68%, NOx up to 75.96% and CO2 up to 69.38% for 10min.
