Abstract

The significance of tire disposal, an attractive waste to convert into burning oil or absorber etc., has been increasing day by day. However, if it does not change into a useful form, it will damage the nature and the living things. Thus, pyrolysis, a well-known method, which is used to convert recycle tire waste into gas, liquid and char. On the other hand, the waste pyrolysis oil or waste tire oil (WTO) has a substantial avaliable calorific value similar to those of fossil fuels. Due to pyrolysis reaction, high amount of sulfur is detected in the WTO; therefore, another step of explosion applied to WTO to decrease sulfur and also re-upgrade quality of oil with such catalysts as Calcium Oxide (CaO) and Natural Zeolite (NZ) at a ratio from 2 to 10 with an increase of 2 for each step, individually. It is noticed that distillation test is a key analysis for separation discrimination of rich or lean quality fuel. As a consequence of mixture of catalyst-WTO reactions, the best curve was observed at a 10% CaO-WTO mixture which was close to diesel#2 and the mixture was separated into two new fuels as light (Gasoline Like Fuel or abbreviated as GLF) and heavy one (Diesel Like Fuel or shortened as DLF) due to temperature differences. According to distillation, FT-IR, NMR and UV–vis were used to analyze WTO, GLF and DLF for defining their characterization as well. Thus, the characterization result data of samples have quasi-equivalent with standard petroleum in open literature, and can be combusted in engine as well.

  • Plastic and tire waste are viable feedstocks for alternative fuels because they are composed of long-chain polymers that can be thermally depolymerized into smaller hydrocarbon molecules analogous to conventional fuels and often with high calorific values.

    “The fundamental chemical basis allowing plastic and tire waste to be viable feedstocks for alternative fuels lies in their composition of long-chain polymers, which can be thermally depolymerized into smaller hydrocarbon molecules analogous to those found in conventional fuels, often possessing high calorific values [321,322].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
