Carbon dioxide capture using Adsorption Technology in Diesel Engines

Abstract

Diesel engines are the major sources of Carbon dioxide (CO 2 )emission in the transport sector compared to petrol engines and for this reason the current trend in diesel engine research is shifting towards reduction of CO 2 emissions. Removal of CO 2 from the engine exhaust and recycling it in industrial applications could be a better solution for CO 2 reduction. Out of a few methods available, adsorption and desorption of the CO 2 using zeolite is an ecoomical way to remove CO 2 from the engine exhaust. In this study, CO 2 from the exhaust of a Kirloskar TAF AV1 type diesel engine is captured using zeolite 13X. To optimize the capture of CO 2 from theengine exhaust, three quatities of zeolite are considered in this study. 100, 150 and 200 grams of zeolite is stored in a cylindrical chamber and placed in the exhaust line of the engine. A surge tank is connected before the zeolite chamber to reduce the backpressure of the engine caused by the addition of zeolite chamber. Emissions such as CO 2 ,Unburned hydrocarbon (HC) and Carbon monoxide (CO) before and after the chamber are measured to study the CO 2 adsorption capacity of the zeolite 13X. From the results, it was found that low-cost zeolite sieves can adsorb upto a maximum of 45% of the CO 2 emission from the engine exhaust.
