Technical Specification of Waste Tyre/Rubber Pyrolysis
1 Scope
This Standard specifies the general rules, comprehensive resource utilization products,
pollutant emission control and marking, packaging, storage and transportation for the
waste tyre/rubber pyrolysis production.
This Standard applies to the waste tyre/rubber pyrolysis production, as well as the
environmental impact assessment, design, completion acceptance and operation
management of new, rebuilt, and expanded waste tyre/rubber pyrolysis production
facilities.
This Standard is not applicable to waste rubber and plastic products listed in the
Directory of National Hazardous Wastes, and neither is applicable to the waste rubbers
such as waste nitrile rubber, fluorine rubber, neoprene, etc. treated by the pyrolysis
method.
2 Normative References
The following documents are essential to the application of this document. For the
dated documents, only the versions with the dates indicated are applicable to this
document; for the undated documents, only the latest version (including all the
amendments) is applicable to this document.

Gaseous Pollutants Emitted from Exhaust Gas of Stationary Source
GB 30000.7 Rules for Classification and Labelling of Chemicals - Part 7:
Flammable Liquids
condensable combustible gas.
3.4 Pyrolysis oil derived from waste tyre/rubber
Oil products that are produced by pyrolysis using waste tyre/rubber as raw materials.
3.5 Pyrolysis recovered carbon black
A solid product rich in carbon black that is produced by pyrolysis of waste tyre/rubber.
3.6 Recycled steel wire from pyrolysis
The solid product of steel wire that is recovered in the pyrolysis process of waste
tyre/rubber.
3.7 Non-condensable combustible gas
Combustible gas that fails to condense after passing through the oil-gas cooling
system.
3.8 Volatile organic compounds; VOCs
All organic chemicals that participate in atmospheric photochemical reactions.
NOTE: This Standard defines different VOCs control indicators according to different control
objects and detection methods:
a) For the VOCs in the exhaust gas discharged from the exhaust gas cylinder, use "non-
methane hydrocarbon" as the control index;
b) For the escape of VOCs generated by the leakage of components such as pyrolysis
equipment and pipelines, use a detector that meets the specified performance
requirements to detect the VOCs concentration at the specified location as the control
index.
3.9 Non-methane hydrocarbon
The general term for all hydrocarbons except methane (by carbon).
NOTE: Non-methane hydrocarbon is used in this Standard as a comprehensive control index
for exhaust volatile organic compounds (VOCs) emissions.
3.10 VOCs detector
A portable detection instrument, based on the principles of photoionization and infrared
principles, that can quickly display the concentration of volatile organic compounds in
the air.
is less than 120kW·h/t; and the energy consumption of pyrolysis process is less than
80kW·h/t. The consumption of only non-condensable combustible gas produced by the
system as a heat source is not included in the calculation. The energy consumption for
deep processing of pyrolysis recovered carbon black and recycled steel wire from
pyrolysis shall be calculated separately; and the comprehensive energy consumption
calculation method of each product shall be in accordance with GB/T 2589.
4.2.3 The non-condensable combustible gas and flue gas waste heat recycling
technology shall be fully used; adopt energy-saving and environmentally friendly
heating methods to reduce energy consumption and flue gas emissions.
4.2.4 The temperature of the solid product discharge of the pyrolysis device shall be
lower than 80°C; and the solid product discharge system shall be airtight to prevent
dust pollution.
4.2.5 A combustible gas detection and alarm system shall be installed in the complete
system of waste tyre/rubber pyrolysis, and its setting shall comply with the provisions
of SY/T 6503.
4.3 Equipment
The technical requirements of the complete set of equipment for waste tyre/rubber
pyrolysis shall comply with the provisions of GB/T 32662.
5 Comprehensive Resources Utilization Products
5.1 Pyrolysis oil derived from waste tyre/rubber
The pyrolysis oil derived from waste tyre/rubber is the main liquid product of waste
tyre/rubber pyrolysis. Its calorific value is one of the important indicators to measure
the comprehensive utilization of resources. The calorific value of the product shall be
determined in accordance with the method specified in GB/T 384; the calorific value is
about 38MJ/kg~46MJ/kg. The specific technical indicators and requirements of
pyrolysis oil derived from waste tyre/rubber shall be negotiated and determined by both
parties.
5.2 Pyrolysis recovered carbon black
The pyrolysis recovered carbon black is the main solid product of waste tyre/rubber
pyrolysis. After pyrolysis regenerated carbon black has been removed, crushed, and
selected, it can be further processed into granulation to produce the pyrolysis
recovered carbon black that meets the market demand. The technical indicators and
requirements are determined by the supplier and purchaser through consultation.
5.3 Recycled steel wire from pyrolysis
ρ’ – actually-measured emission concentration of air pollutant, in mg/m3.
6.7 The device or nozzles in the pyrolysis equipment, that are frequently opened (open
at least once every 2 days of operation), shall be equipped with a partial or overall
exhaust gas collection and purification device. The waste gas overflowed during the
blowdown is collected can be discharged after purification treatment. The discharge of
pollutants shall comply with the provisions of HJ 1034.
6.8 The crushing of the pyrolysis recovered carbon black shall be carried out in a
closed system to collect and treat dust.
6.9 The water for waste tyre/rubber pyrolysis production shall be recycled. The
produced wastewater shall be equipped with supporting wastewater collection facilities.
The wastewater shall be treated and recycled in the plant area; the discharging of the
treated wastewater shall comply with the provisions of GB 8978.
6.10 Noise pollution shall be controlled during the whole production process of waste
tyre/rubber pyrolysis; and noise emission shall comply with the provisions of GB 12348.
