An improved process for pyrolyzing worn tires and other organic waste to extract valuable materials and reduce pollution. The process involves heating the waste inside a double-walled reactor using a preheated coolant circulating between the walls. This provides uniform heating without external burners, prevents contamination, and allows efficient extraction of solid, liquid, and gaseous pyrolysis products. Multiple reactors can be used in parallel to increase throughput. The coolant is warmed in a separate boiler.

Waste tire pyrolysis system that avoids explosion risks by using a hot gas generator to maintain proper temperature inside the pyrolysis reactor. The generator uses LPG, diesel, and air injection to generate hot gases that heat the reactor instead of relying solely on waste tire pyrolysis gases. This prevents explosive dust buildup by avoiding exposure of hot pyrolysis products to air. The generator also has cooling air supply to regulate reactor wall temperature.

Flexible pyrolysis apparatus and method for treating carbonizable waste like tires and plastics with different pyrolysis temperatures. The apparatus has multiple reaction chambers of decreasing size. Materials are first pyrolyzed in a larger chamber, then further pyrolyzed in smaller chambers. Gases are directed to different destinations after the second pyrolysis stage. This allows efficient pyrolysis of different materials at optimal temperatures in each chamber. It also enables treating waste like tires with mercury, where some components pyrolyze at lower temps.

Continuous batch pyrolysis system for recycling waste tires into valuable products. The system uses batch processing instead of continuous processing to improve product quality. The system involves batch reactors, heating units, solids processing units, gas/liquid processing units, and control units. The batch reactors pyrolyze waste tires in an oxygen-free atmosphere to produce pyrolysis products like oil, gas, and char. The system optimizes pyrolysis conditions for high quality products. Internal heat conductors in the reactors facilitate rapid heat transfer. This allows efficient batch processing of large volumes of waste tires to recover valuable products like oil and char. The system scales up to commercial size.

A pollution-free method and plant for recycling organic waste like tires and plastics without generating pollutants. The method involves two-stage coal preparation using a reactor for pyrolysis. The pyrolysis converts the waste into pyrolysis oil, carbon, and gases. The carbon is recovered and used as fuel. The gases are burned to provide heat for the reactor and excess used as fuel. The oil is further refined. This closed-loop recycling avoids pollution compared to open-air pyrolysis.

A pyrolysis reactor for waste tires that improves efficiency and reduces costs by shortening the pyrolysis and cooling times. The reactor design features a bottom-mounted heater to create high temperatures inside. It also has an intake pipe near the reactor wall to prevent waste tires from entering the gas stream. The reactor rotation speed is increased to shorten pyrolysis time. Cooling is accelerated by circulating cold air through the reactor during rotation. This allows quicker char removal and reactor turnover. The shorter processing times reduce energy consumption compared to conventional reactors.
