“…One of the most promising ways to recycle automobile tires is the steam gasification technology [4][5][6][7]. Its advantages are explosion safety, neutralization of environmentally hazardous compounds in the vapor-gas mixture, higher the energy value of gas-phase products, activation of the carbon particles pore structure and the possibility of the smooth regulation of raw materials thermal conversion.…”

The technical characteristics of liquid hydrocarbons obtained by steam gasification of the recycled automobile tires were studied as well as the features of their combustion process. Steam gasification of grinded tires was carried out in a tubular reactor using superheated steam with 500°C temperature and 5 kg/h mass flow rate. The obtained characteristics were compared with a traditional liquid fuel oil. The technical characteristics were determined via the standard analytical methods. An ignition and a combustion of liquid hydrocarbon samples were carried out in the combustion chamber at different temperatures of heating medium Tg = 450–700°C. Gas-phase combustion products were analyzed using a flow-through gas analyzer. It was found that liquid hydrocarbons were characterized by a low pour point (-43°C – (-52) °C) and comparable to calorific value of traditional fuel oil (40.56–43.3 MJ/kg). In addition, the studied samples of liquid hydrocarbons were characterized by a lower ignition delay time (by 56 %, on average) and flame burning time (by 30 %, on average). Combustion process of the studied samples (including traditional fuel oil) was accompanied by the formation of micro-explosions.

The huge amount of waste tires (WTs) have been disposed to surroundings which cause dangerous effect on nature. Owing to recycled WTs, the pyrolysis is a good technique to dismiss harmful effect of the WTs, by converting into gas, liquid and solid. The present study has two steps of liquefaction at a batch reactor. Firstly, conversion of the WTs into gas, waste tire oil (WTO) and char. Then the WTO were blended with calcium oxide (CaO) or natural zeolite (NZ) at different ratio and pyrolyzed to obtain high quality oil, similar to gasoline fuel (GF) or diesel fuel (DF). The distillation curve is a good key to define fuel quaility. Thus, 10% CaO-WTO blend curve near to the DF. Unfortunately, the mixture was distillated at 54 o C, lower than the DF. Therefore, the blend was separated into two fractions due to intial-final boiling points as 150 o C to 360 o C, named as Diesel like fuel (DLF); between 54 o C to 150 o C, called as gasoline like fuel (GLF). Finally, samples were analyzed to characterizate by GC, ICP-MS, TGA and DSC for similarities of conventional fuels. The heavy metals and other elements of samples were analyzed by ICP-MS techniques. TGA is a good test to determine the oxidative and thermal stabilities of fuel while DSC was used to determine crystallization onset temperature on fuel samples. GC analysis is done for detemening of gas heating value and beside gas contents which has a comprehensive with standard burnable gas. Based on GLF and DLF with unliquified gas results, all of components of products can be burned in engine without any problem.

“…Tires, the main components of which are the natural and artificial synthetics, carbon black and additional additives such as sulphur, zinc oxide, stearic acid, have very high resistance to abrasion and corrosion. Therefore, degradation of tires on their own is very difficult and unlikely [3][4][5][6].…”

Effect of curing methods and scrap tyre addition on properties of mortarsMechanical, thermal conductivity, and porosity properties of scrap tyre incorporated mortars are examined experimentally in this study for various curing conditions. Cement mortars were prepared by adding 0%, 1%, 5%, 10% and 18% of scrap tyre by cement weight, and the mortars were subjected to three curing procedures for 14 weeks. The lowest thermal conductivity values were obtained on samples containing 18% of scrap tyre by water curing and wetting-drying curing as 1.09 and 1.14 W/mK, respectively. The maximum compressive strength of 61.5 MPa was obtained on a pure sample cured by wetting and drying, while the flexural strength of pure and a 1% additive incorporated samples, which were also cured by wetting-drying, amounted to 9.1 and 8.2 MPa, respectively.
