“…To reduce exhaust emissions, some researchers also conduct research with the chemical reaction of ammonia, as has been done by [16]. The solid-SCR (selective catalytic reduction) system using ammonium carbamate (AC) is designed to increase the efficiency of reducing NOx emissions and compensate for the deficiency of UWS (urea aqueous solution).…”

The use of fossil fuels in transportation equipment, especially motorized vehicles, will have an extraordinary effect on air pollution. Therefore, air pollution becomes very important problem today. The amount of percentage of air pollution from transportation sources in Indonesia is 70.5 % CO, 18.34 % HC, 8.89 % NOx, 0.88 % SOx, and 1.33 % particulate matter. Given the danger of exhaust emissions, especially carbon monoxide which can cause death for humans who inhale it, therefore efforts are needed to control air pollution from motorized vehicles. There are several methods that can be used, one of which is to use adsorbents. Activated carbon can be used as an adsorbent. One alternative that can be applied as an adsorbent is peat soil-activated carbon which is abundant and easy to make as an adsorbent. By utilizing the abundant peat-soil which is a great potential area of Banjarmasin, South Kalimantan. In this experimental study; model l has a diameter of 20 mm, model 2 has an outside diameter of 20 mm and an inside diameter of 10 mm, and model 3 is without adsorbent. The length of this model is the same. Testing with a 2005 Honda Kharisma motor vehicle with an engine speed of 1000, 2000, and 3000 rpm. CO and HC emission tests using a gas analyzer were carried out. Testing was also carried out using a dyno test to determine the engine performance of a motorcycle that was installed with an adsorbent on the exhaust gas. The results showed that peat soil adsorbents with perforated circle designs can reduce CO gas emissions by 55 % compared to the others. Besides that, the use of peat soil adsorbents with hollow circle designs can also reduce HC gas emissions by 3.51 %. The results of the engine performance test showed that there was no significant effect of using this adsorbent on torque and power. In conclusion, peat soil adsorbents used to reduce exhaust emissions in motorized vehicles can be applied

“…The potential of solid SCR systems has also been explored in non-vehicular applications like off-road engines and marine engines. A solid SCR system was designed for NOx reduction from a 1.1 MW marine electric generation engine by Woo et al 44 The deNOx performance of the system was evaluated and compared with the already installed UWS system. It was observed that the tailpipe NOx for the solid SCR system was 15% of the UWS SCR system.…”

Several NOx reduction technologies have been developed to alleviate the impact of NOx emissions on the environment and meet the more stringent upcoming emission legislation. Although UWS is the most commonly used NOx reduction technology, it has various issues listed in this article. Several alternative technologies based on solid materials as a gaseous ammonia source are developed to eradicate these issues. This article reviewed the solid SCR systems currently being developed as an alternative to UWS for deNOx applications. Furthermore, the chemistry of the various ammonia storage materials used in these systems and their potential to produce gaseous ammonia for use in SCR have been evaluated. Furthermore, the deNOx performance of ammonium salts-based and metal ammine chlorides-based solid SCR systems have been evaluated. Besides, we have discussed various numerical modeling and simulation approaches applied to develop these solid SCR systems. Due to gaseous ammonia injection solid SCR systems offer better NOx conversion efficiency compared with UWS systems, especially at low exhaust gas temperatures. The authors believe this article will be helpful for future studies in this field to further develop and establish these solid SCR systems as a viable alternative deNOx technology.
