Liquid fuel production from waste tyre pyrolysis and its utilisation in a Diesel engine

摘要: Abstract The possibility of using, in Diesel engines, a liquid fuel derived from waste synthetic polymeric matrices, such as scrap tyres, was evaluated this paper. obtained by combined thermo-mechanical cracking process carried out at moderate temperatures (300–500 °C). Fuel properties the pyrolytic oil were analyzed with standard methods, showing density, viscosity, calorific value and flash point comparable to those commercial automotive (DF), but significantly higher sulphur content lower cetane number. Also other pyrolysis products (gas solid) analysed terms yield composition order individuate their potential re-uses. A preliminary engine investigation on 440 cm 3 single-cylinder using two tyre (TPO)–Diesel blends: TPO20 (containing 20% TPO 80% DF volume basis) TPO40. cytotoxicity genotoxiticy particulate exhaust emissions D7 strain Saccharomyces cerevisiae yeast cells vitro short-term tests. Results compared only. Engine performance, different speed loads, showed that use not involve significative differences torque, power, specific consumption respect DF, while TPO40 leads general worsening combustion characteristics. Lubricant analysis, made end tests, certain level contamination. No meaningful mechanical inconvenience occurred during experimental activity. In assays particulates similar cytotoxic potency no genotoxic effect for TPO/Diesel blend emissions.
