Waste polypropylene plastic conversion into liquid hydrocarbon fuel for producing electricity and energies

Thermal degradation of polypropylene (PP) waste plastic is batched process studied for the purpose of converting waste PP into liquid hydrocarbon fuel and useful chemicals. The stainless steel reactor is used for conversion to fuel; this reactor chamber has a diameter of 6 inches, height of 18 inches and a temperature input capacity of 500°C. The temperature of 150–370°C was used for PP conversion into fuel. We have also used 1 kg PP waste plastic for conversion into fuel and HZSM-5 catalyst of 5% by preference was used by total weight of sample. Yield percentages obtained from PP to fuel are 92%, 2% light gas and 6% residue. Experimental finish time was 5.25 hours. By gas chromatograph/mass spectrometry instrumental analysis, the PP to fuel carbon range is found to be C3‒ C25, and the low sulfur level is detected by the American Society for Testing and Materials (ASTM) test method to be<1.0 ppm.

New alternative energy from solid waste plastics

Generation of electrical energy from imported fossil fuels is subject to the price fluctuations of the global marketplace and, thus, constitutes a major expense in its distribution to the end users. Even with the current low prices for fuel, residents and businesses in the United States pay a significant price for their utilities, if not higher than many other countries in the world. Emissions from the evaporation and combustion of these traditional fossil fuels contribute to a range of environmental and health problems, causing poor air quality, and emitting greenhouse gases that contribute to global warming. Alternative fuel created from domestic sources has been proposed as a solution to these problems, and many alternative fuels are being developed based on solar, wind, biomass, hydropower, fuel cell, geothermal, etc. Natural State Research, Inc. (NSR) has developed a new alternative hydrocarbon fuel which is produced from abundant waste plastic materials. The existing NSR process efficiently converts waste plastics into a reliable liquid fuel. NSR has demonstrated the feasibility of producing this fuel at the laboratory scale and a pilot plant is being built to scale-up this process. Preliminary tests in the NSR laboratory show comparable electricity generation from NSR fuel when compared to that from the commercially available gasoline with octane number 87 (gasoline-87).

First Simple and Easy Process of Thermal Degrading Municipal Waste Plastics into Fuel Resource

Liquid fuel i.e. hydrocarbon fuel obtained from four different types of waste plastics low and high density polyethylene (LDPE and HDPE), polypropylene (PP) and polystyrene (PS) were carried out in a reactor stainless steel system. Each of the plastics has different chemical and physical properties so the experiments were carried out individually for each of them. Simple thermal degradation was used to melt the plastics at temperature ranging from 120 to 400 0 C. Vapor condensation form the melted plastics produced the liquid hydrocarbon product. Similar standards were followed for each of the plastics during the production process. The effect of reaction on quality and yield of the product were investigated. The liquid product formed was analyzed using gas chromatography (GC) with mass spectrometer (MS) (Clarus-500) and FT-IR spectrometer spectrum 100 (Perkin-Elmer). The chemical properties of the liquid product had varied from each plastic. Each of the liquid products contained low sulfur but each of them varied from each other. The waste plastics can also be randomly mixed with each other prior to the liquid production process. The results of mixed plastics production process indicates higher yield percentage than when they are done separately.

E-Waste Cable Plastic Transforming Oil using Sodium Hydroxide with Activated Carbon

Electrical product usages are increase every day all over the world. Electrical component has plastic part and after use all electrical product through as garbage and creating environmental problem. Some percentage of e-waste plastic can recycle and rest of percentage keep as a land fill. E-waste to oil production process performs with sodium hy- droxide and activated carbon in laboratory scale batch process. Temperature range was 200-420 oC and sodium hydroxide was added 5% and activated carbon was added 5% with e-waste plastic. Electronic waste plastic was use 75 gm by weight. Under labconco fume hood experiment was placed in presence of oxygen without vacuumed system. Produce oil density is 0.90 g/ml and fuel was analyzed with Gas Chromatography and Mass Spectrometer (GC/MS) and carbon chain detected C4 to C33. Electronic waste plastic to oil pro- duction conversion rate was 33.6 %, gas production rate was 16.53 % and left over residue 49.87%. Electrical waste plastic to produce fuel can be use petroleum refinery process for further modification to use able internal combustion engines.
