Will the Industry Standards for Oil Yield of Waste Tire Pyrolysis Equipment Change with Technological Development?

The industry standards for the oil yield of waste tire pyrolysis equipment are dynamically adjusted as technology advances, with the evolution of standards being highly linked to technological progress, mainly reflected in the following aspects:

1. Technological breakthroughs directly drive the upgrading of standard indicators

Application of catalytic pyrolysis technology: With the maturity of technologies such as magnetron nanocatalysis and multiphase catalytic reactors, the actual industrial oil yield has stabilized at 45%-50%, and some advanced equipment has even exceeded 50%. This has prompted the updated standards (e.g., GB/T 26731-2024) to raise the requirement for pyrolysis oil recovery rate from the early ≥40% to ≥45%.

Popularization of continuous processes: After fully enclosed continuous pyrolysis technology replaced the traditional batch process, it not only improved the stability of oil yield but also reduced energy consumption and emissions. Industrial specification requirements have clearly encouraged the adoption of continuous equipment, which has indirectly driven the optimization of oil yield indicators.

2. Standard revisions proactively adapt to technological iteration

Dynamic update of existing standards: The original GB/T 26731-2011 standard, which could not adapt to new technologies such as continuous pyrolysis, was revised to GB/T 26731-2024 in 2024, adding clear requirements for pyrolysis temperature control (450-600℃) and oil yield indicators.

Reserving space for technological innovation: Clauses such as "encouraging the adoption of new technologies and processes" in standards like GB/T 32662-2016 reserve space for the integration of future technologies such as catalytic enhancement and intelligent control, ensuring that standards can continuously adapt to technological development.

3. Policy and environmental protection demands accelerate standard upgrading

Driving force of policy orientation: Government departments including the National Development and Reform Commission have set the target of "achieving an average industrial oil yield of 40% by 2025", forcing enterprises to improve efficiency through technological upgrading and thus driving the improvement of standard indicators.

Integration of environmental protection and energy efficiency requirements: As environmental protection requirements become more stringent, standards focus not only on oil yield but also bind it with indicators such as carbon emissions and energy self-sufficiency rate. For example, standards in regions such as the EU have closely linked oil yield improvement with the application of low-carbon technologies.

4. Future trend: In-depth integration of standards and technology

In the future, industrial standards will follow technological iteration more closely, for instance:

Introducing evaluation indicators for new technologies such as intelligent pyrolysis and low-carbon recovery;

Promulgating product quality standards for pyrolysis oil (e.g., the special pyrolysis oil standard expected to be released in 2026), which will further drive the dual improvement of oil yield and quality in a reverse manner.
