Waste Tires to Synthetic Diesel and Jet Fuel - An Efficient New Process for Waste Refining
Every year in the United States and Canada, between 325 and 350 million scrap tires are generated. Approximately 20% of these tires are reused as "retreads" - often for trucks: the old tread is ground off the tire and replaced with a new tread. About 25% of all used tires are still dumped in landfill sites. Other tires are incinerated (so-called "tire derived fuel", or TDF). Burning 1 ton of waste tires such as is done in many power plants produces about 450 kg of toxic gases. The damage to the environment is obvious.
BioSynEnergy
is collaborating with respected engineering firms in the US and EU that have developed and commercially deployed proprietary, highly efficient processes for converting waste tires (and even plastic waste) into high quality, synthetic fuels (gasoline, diesel and jet fuels that rival ane even surpass the quality and energy value of products refined from petroleum. Depending upon the cost of waste tires (in some locations, a lucrative tipping fee is paid for tire disposal), the production cost per gallon of synthetic fuel will usually vary between $2.65 USD and $3.75 USD per gallon.
Controlled, ultra-clean, close-coupled thermolysis-gasification technology first converts waste tires/plastics into very pure syngas (hydrogen + carbon monoxide). This syngas is then transformed via a two-step, catalytic , refining process into synthetic diesel and jet fuel (gasoilne may also be produced if desired). Although waste tires contain sulphur from vulcanization (tires contain 40% natural rubber), the synthetic fuels we produce from them contain less than 0.1% sulphur and no other contaminants.
Other waste tire conversion systems, most of which use some kind of pyrolysis platform, produce complex pyrolytic oils that vary widely in chemical make-up, are highly corrosive, and often contain contaminants. The BioSynEnergy process produces a continuous stream of high quality, synthetic fuels that can be used in diesel or jet engines without further processing or filtering.
Our technology is modular and scalable and can be deployed quickly. The basic modular unit converts 24 tons of waste tire shreds daily and requires about 1/2 acre of space; if more processing capacity is desired, additional 24-ton units can be added. With no smokestack, no effluent, low noise, EU environmental certification, and a low building profile, tthe BioSynEnergy system can be located anywhere. The system is controlled with user-friendly, PC-based software that automates and monitors the entire process. A variety of sensors transmit performance data continuously to the local operator and over an Internet connection and a central monitoring station to quickly identify even the slightest problem or anomaly.
The system, with only slight modifications and software adjustments, can also profitably produce synthetic fuels from biomass, including any species of microalgae (see www.panalgaea.com).
