The interest and relevance of the present paper is in the current waste plastics valorization scenario. The rapid depletion of fossil sources carbon as crude oil and their ever-increasing costs has led to an intensive search for alternative fuels. The renewable green fuel (RGF) or alternative fuel was obtained from waste low and high-density polyethylene (LD-PE, HD-PE) or polyolefin’s and computer-body through pyrolysis process using a CdCO3 from 23 °C to 400 °C. Five types of hydrocarbons were observed through 2D GCxGC/TOFMS, such as 7.621 % paraffin’s, 53.66 % branched / cyclic hydrocarbons, 14.83 % aromatics, 0.37 % phenanthrenes, and some unclassified compounds were 27.11 %. The research octane number of RGF was 88.29. The bromine number of RGF is 34.03 %. RGF was suitable for diesel engines and diesel furnaces without any upgrading. During the first, second and third pyrolysis experiments, 98 g, 95 g and 100 g (wt %) waste granules with 2 g, 5 g and 0 g (wt %) CdCO3 into RGFs were 85 %, 89 % and 80 % collected; uncondensed gases were 14.22 %, 10.15 % and 19.52 % collected; the residue were 0.78 %, 0.85 % and 0.48 % collected.

Makalah ini membahas tentang pengaruh laju aliran bahan bakar CNG (compressed natural gas) terhadap performa kendaraan roda empat jenis minibus. Pengaturan dan pengujian dilakukan untuk mencari setelan laju aliran CNG yang terbaik agar performa kendaraan optimal. Tahap pertama dari penelitian ini adalah pemasangan peralatan kit konverter tipe injeksi sequensial pada kendaraan. Selanjutnya dilakukan pengujian performa kendaraan menggunakan  dyno  test  atau  sasis  dyno.  Pada  awalnya,  bahan  bakar  yang  digunakan  adalah  Pertamax  RON (research  octane  number)  92  yang  kemudian  diganti  dengan  CNG.  Dari  pengujian  dua  bahan  bakar  tersebut diketahui bahwa terjadi penurunan daya dan torsi kendaraan bila menggunakan CNG. Tahap berikutnya adalah melakukan pengaturan laju aliran CNG dengan cara mengatur durasi penyemprotan injektor. Hasil uji yang ditampilkan dalam bentuk grafik putaran terhadap daya dan putaran terhadap torsi memperlihatkan bahwa performa kendaraan  berbahan  bakar  CNG  dengan  pengaturan  laju  aliran  gas  meningkat  sekitar  3%.  Sedangkan  bila penggunaan CNG dibandingkan dengan Pertamax RON 92, terjadi penurunan daya dan torsi pada kendaraan sebesar 12,4% dan 23,7%.Kata kunci : ratio laju udara, CNG, kit konverter, laju aliran gas, mesin bensin

The most advantageous way of managing plastics, according to circular economy assumptions, is recycling, i.e., reusing them. There are three types of plastics recycling: mechanical, chemical and energy recycling. The products of the pyrolysis process can be used for both chemical and energy recycling. Possibilities of further use of pyrolysis products depend on their physicochemical parameters. Getting to know these parameters was the aim of the research, some of which are presented in this article. The paper presents the research position for conducting the pyrolysis process and discusses the results of research on pyrolysis products of waste plastics. The process was conducted to obtain the temperature of 425 °C in the pyrolytic chamber. Such a value was chosen on the basis of my own previous research and literature analysis. The focus was on the migration of sulfur and nitrogen, as in some processes these substances may pose a certain problem. Studies have shown high possibilities of migration of these elements in products of pyrolysis process. It has been shown that the migration of sulfur is similar in the case of homogeneous and mixed waste plastics—it immobilizes mainly in pyrolytic oil. Different results were obtained for nitrogen. For homogeneous plastics, nitrogen immobilizes mainly in char and oil, whereas for mixed plastics, nitrogen immobilizes in pyrolytic gas.

In the present work, the effect of adding ethanol or methyl tertiary butyl ether (MTBE) to gasoline on the regulated and unregulated emissions from an internal combustion engine with a typical three-way catalyst was studied. The addition of ethanol to fuel (10% w/w) increased both the research octane number and the Reid vapor pressure of the fuel, whereas adding 11% w/w MTBE caused an increase only in the research octane number of the fuel. When the fuel contained MTBE, less hydrocarbons, carbon monoxide, and acetaldehyde were emitted in the tailpipe. The increased emissions of acetaldehyde and ethanol were the main disadvantages of using ethanol.

Thermal and catalytic pyrolysis of virgin low-density polyethylene (LDPE), high-density polyethylene (HDPE), polypropylene (PP) and mixtures of LDPE/PP were carried out in a 200 mL laboratory scale batch reactor at 460 °C in a nitrogen atmosphere. Thermogravimetric analysis (TGA) was carried out to study the thermal and catalytic degradation of the polymers at a heating rate of 10 °C/min. The amount of PP was varied in the LDPE/PP mixture to explore its effect on the reaction. In thermal degradation (TGA) of LDPE/PP blends, a lower decomposition temperature was observed for LDPE/PP mixtures compared to pure LDPE, indicating interaction between the two polymer types. In the presence of a catalyst (CAT-2), the degradation temperatures for the pure polymers were reduced. The TGA results were validated in a batch reactor using PP and LDPE, respectively. The result from thermal pyrolysis showed that the oil product contained significant amounts of hydrocarbons in the ranges of C7–C12 (gasoline range) and C13–C20 (diesel range). The catalyst enhanced cracking at lower temperatures and narrowed the hydrocarbon distribution in the oil towards the lower molecular weight range (C7–C12). The result suggests that the oil produced from catalytic pyrolysis of waste plastics has a potential as an alternative fuel.

Rapid Pyrolysis

Of the different methods for recycling plastic, pyrolysis offers the possibility to overcome the limitations of mechanical recycling, which requires large amounts of clean, separate and homogeneous plastic waste to ensure the quality of the final product. Pyrolysis is the chemical decomposition of plastic materials by thermal degradation in the absence of oxygen. The plastic waste is introduced into a chamber, where it is subjected to high temperatures, and the gases generated are condensed in order to obtain a distillate hydrocarbon. This paper presents the results obtained from the pyrolysis of plastic waste mixtures of polypropylene, high density polyethylene, and low density polyethylene. In a first stage, the plastic waste is subjected to a rapid pyrolysis process at temperatures of 440-450 °C, obtaining a mixture of heavy hydrocarbons. Subsequently, these hydrocarbons are subjected to a distillation process, first at a temperature of 180 °C, where a hydrocarbon with properties similar to those of gasoline is obtained, and then at a temperature of 360 °C, yielding a hydrocarbon with properties similar to those of diesel.
