Making of the coconut shell-based activated carbon filter constituent
The materials involved in this process are the following: 8.5-inch insulated stainless-steel pipe, metal screens/meshes, rubber, two 1-inch sponge gourd, and two 0.5-inch steel wool. The researchers will first mark partitions from the tube with measurements 3in, 4.5in, and 1in (as reflected in Figure 3). The researchers will then cut-open the sides of the 4.5-inch partition without entirely tearing off the side of the cut to somehow make a “lid.” Next, the researchers will cut the metal screens/meshes into four circles with a circumference the same as that of the hole of the 8.5-inch pipe. Then, the researchers will sandwich the edge of the circular metal screens/meshes with rubber to provide friction. This method prevents the metal screens/meshes from displacing due to the force of the air expelled through the main tailpipe. Lastly, the researchers will fit the circular metal screens/meshes, sponge gourds, and steel wools in the designated parts of the 8.5-inch pipe (as reflected in Figure 3).
Making of the coconut shell-based activated carbon filter constituent
The materials involved in this sub-process are the following: coconut shell-based activated carbon, 1.5in x 7in pad of mesh, and water. First, the researchers will crush the coconut-shell based activated carbon while dipping the pad of mesh in water. The researchers will then put the crushed activated carbon on the pad of the mesh. Afterward, they will roll the mesh to secure the crushed activated carbon inside.
Making of pulverized seashells filter constituent
The materials involved in this sub-process are the following: mussel shells. First, the researchers will mechanically pulverize the mussel shells through pounding and grinding. Then, the researchers will subject the crushed mussel shells to calcination (roasting) under direct heat or fire. This process is to reduce the calcium carbonate component of the mussel shells into calcium oxide and to grind it to powdered form further. Aside from this, the adhesive properties of the mussel shells will also develop after the calcination. Next, the researchers will pour the pulverized mussel shells into a cylindrical molder of height 1 inch and a diameter of 2.5 inches. The researchers will leave the mussel shells on airtight (to avoid contact from carbon dioxide) until it dries and hardens completely.
Installing the filter constituents inside the muffler extension
After preparing the filter constituents individually, the researchers will fit these constituents inside the 8.5-inch insulated stainless-steel pipe, as reflected in Figure 3.
Testing of the prototype and analysis of results
The test will include filtering carbon dioxide from a source, letting it flow through the tube with the treatment, and out to a carbon dioxide meter. The researchers will conduct the test in an emission test center located in every place in the country. The carbon emission test will measure the final carbon dioxide output of the vehicle, as well as other greenhouse gases. After the experimentation, the researchers will then analyze their treatment in its efficiency in filtering carbon dioxide. The researchers will examine the procedure in terms of carbon emission. The carbon emission includes measuring the count of carbon dioxide (CO2), carbon monoxide (CO), oxygen (O2), hydrocarbon (HC), and nitrous oxide (NOx).
