Air pollution is a leading public health concern that needs to be tackled. About 30% of the total greenhouse gas emissions, such as CO, HC and NOx are due to automobiles. By 2030, the US Department of Transportation aims to reduce light duty vehicle emissions by 18%. This can be achieved by public policy approaches such as implementing emission control norms and performance improvements such as exhaust system design. In this work, the implementation of a pure Zeolite catalyst to reduce the exhaust CO2 emission of a SI engine is studied theoretically and experimentally. The complete exhaust system including the catalytic converter, muffler, and pipes is modeled in a 3D CAD modeling software, using the engine specifications. Current expensive precious metals in the catalytic converter are replaced with a binding agent along with Zeolite catalyst. The exhaust system is fabricated and the experimental tests are performed at the maximum engine RPM to obtain threshold emission reduction values. The results showed obtaining an emission reduction of CO2 at a lower cost. Furthermore, it is found that employing Zeolite sieves can further reduce the pollutant emission at a similar cost.

Co2 Emission Reduction

The pulp and paper (P&P) sector is a dynamic manufacturing industry and plays an essential role in the Austrian economy. However, the sector, which consumes about 20 TWh of final energy, is responsible for 7% of Austria’s industrial CO2 emissions. This study, intending to assess the potential for improving energy efficiency and reducing emissions in the Austrian context in the P&P sector, uses a bottom-up approach model. The model is applied to analyze the energy consumption (heat and electricity) and CO2 emissions in the main processes, related to the P&P production from virgin or recycled fibers. Afterward, technological options to reduce energy consumption and fossil CO2 emissions for P&P production are investigated, and various low-carbon technologies are applied to the model. For each of the selected technologies, the potential of emission reduction and energy savings up to 2050 is estimated. Finally, a series of low-carbon technology-based scenarios are developed and evaluated. These scenarios’ content is based on the improvement potential associated with the various processes of different paper grades. The results reveal that the investigated technologies applied in the production process (chemical pulping and paper drying) have a minor impact on CO2 emission reduction (maximum 10% due to applying an impulse dryer). In contrast, steam supply electrification, by replacing fossil fuel boilers with direct heat supply (such as commercial electric boilers or heat pumps), enables reducing emissions by up to 75%. This means that the goal of 100% CO2 emission reduction by 2050 cannot be reached with one method alone. Consequently, a combination of technologies, particularly with the electrification of the steam supply, along with the use of carbon-free electricity generated by renewable energy, appears to be essential.
