“…While preparing the pyrolysis oil, it is suggested that the catalysts should be used in order to increase the liquid proportion in the yield. In this regard Miandad, et al [30] performed gas chromatography-mass spectrometry analysis and found that use of catalyst like activated alumina for the production of waste tyre pyrolysis oil reduced the aromatic hydrocarbon compounds to 60.9% compared to 93.3% when produced without catalyst. Salan et al [31] have also used catalysts like clinoptilolite and meerschaum for the catalytic pyrolysis of pulper rejects and compared their performance.…”

The need of the substitute fuels in compression ignition engines has been the major requisite of the today's world. Due to progressive diminution in crude oil and their subsequent environmental effects many researchers are working on various alternative fuels like biodiesel, methanol, alcohols, CNG, LPG, biogas. Fulfillment of the stringent emission norms is also a great concern as the fuel suggested should also offer the desired performance and should be economically and environmentally proven. Hence the oil extracted from the waste tyre is the biggest emanating fuel tested for its behavioral analysis when blended with diesel on single cylinder Variable compression ratio diesel engine. Trials are conducted with 100% diesel and then 10%, 25%, 35%, 50%, 60%, 75% and 90% TPO (tyre pyrolysis oil) blends with diesel with varying the load. It is observed that the various performance indicators like BP, IP and BMEP are boosted with rise in the proportion of TPO in the fuel oil for all loads. Increase in the BTE is found highest for moderate load up to 2.6 kg and maximum for TPO 90. Mechanical efficiency found to be maximum at TPO 35 at higher load. Lower specific fuel consumption obtained for TPO10 blend at low load and maximum at TPO 60. From the emission analysis it is found that CO emission tends to reduce up to moderate load, but increases consistently further with the load. HC emission found to be decreased with increase in TPO proportions with minimum for TPO 90 at all loading conditions. CO 2 emission gradually increased with progressive rise in the load and increases rapidly for higher loads. NO x emission and smoke increased gradually with increase in the TPO proportion. Analyzing the performance of TPO for different proportions with diesel, TPO 90 is the better alternative to enhanced output and efficiency. Whereas for lower fuel consumption and emissions TPO 10 be recommended. Again it is also seen that moderate proportion of TPO (TPO35) gives highest cylinder pressure and reduction in the fragrant sulfur.

“…The use of calcium carbonate (CaCO 3 ) in the pyrolysis of horse manure allows for lower temperatures due to the catalytic effects of CaCO 3 as a possible source of CO 2 [34]. Co-pyrolysis of different plastic mixtures [35], as well as the use of catalysts [36][37][38][39], has also yield interesting results concerning the productivity and quality of the PDO components.…”

Processing of biomass feedstocks to produce energy, fuels, and chemicals via a combination of different applied technologies is considered a promising pathway to achieve sustainable waste management, with many environmental and economic benefits. In this chapter, we review the current state of the main processes associated with energy recovery and biofuel production under the concept of waste biorefineries. The reviewed technologies are classified into thermochemical, biological, and chemical, including combustion, gasification, steam explosion, pyrolysis, hydrothermal liquefaction, and torrefaction; anaerobic digestion, fermentation, enzymatic treatment, and microbial electrolysis; and hydrolysis, solvent extraction, transesterification, and supercritical conversion. Their brief history, current status, and future developments are discussed within a perspective of valorization and managing of current waste streams with no solution.

“…Os resultados indicam que a adição de 10 % de CaO aparentemente piora as condições de troca térmica no reator, levando a uma pirólise incompleta da borracha inicial. Miandad e colaboradores 16 obtiveram resultado semelhante utilizando Ca(OH)2, com 55 % de resíduo sólido. Com relação à capacidade de sequestro de enxofre durante a pirólise, a presença de CaO levou a uma redução modesta, mas significativa, da quantidade de enxofre na fração líquida de 0,77 para 0,58 %, uma redução de 24 %.…”

The increased generation of waste tires in recent decades has raised concerns and questions about its impact on the environment. The simple disposal is no longer admissible and the use of new processes imposes itself. The chemical recycling through the pyrolysis of the waste tires is one of these alternatives, transforming the material into gaseous, liquid and solid fractions that can be completely reused, even in the productive chain of the tires. This work evaluates the pyrolysis of rubber waste from discarded tires in the absence and presence of different catalysts and characterizes the obtanied fractions based on IR, 1 H and 13 C NMR analysis. The focus was on the liquid fraction, which by its characterization has great potential as a source of raw materials for the chemical industry or for use as fuel.
