FAQ's about Arterran

 

 

What is Arterran Biofuel?

 

Arterran Biofuel is a renewable solid biofuel made from cellulosic feedstocks like wood, manure, agricultural waste and other waste. Cellulose is the most abundant organic polymer on Earth. The cellulose content of cotton fiber is 90%, that of wood is 40–50% and that of dried hemp is approximately 45%.

 

 

What process does Arterran use to make its Biofuel?

 

Arterran’s process uses recyclable catalysts, increased temperature and pressure to create our solid biofuel. The feedstock is combined in a large prep tank with catalyst and agitated. Excess heat from processing is repurposed to the slurry tank to increase the temperature. Once a thoroughly mixed slurry is achieved the material is transferred in batch size to the bioreactors.

 

The bioreactors heat and maintain the slurry at the desired temperature and pressure for a specific time to allow the reaction between the catalyst and the feedstock.

 

After processing the batch slurry is separated, the solids are ready to be compressed and the catalyst is recycled to the prep tank.

 

What is the value of the energy in Arterran Biofuel?

 

To begin we will use the starting point of Megawatt hours per tonne.

 

One Megawatt hour is equal to 3,412,124 Btu and is valued at $31.45 USD per.

(Price data is the average of Bid/Ask from Argus Biomass Markets 

 

Energy content of wood pellets:

 

7,500 Btu/lb. = 16.5 million Btu/t = 4.83 MWh/t = $150.00 per tonne

8,500 Btu/lb. = 18.7 million Btu/t = 5.48 MWh/t = $172.35 per tonne

 

Energy content of AR Biofuels:

 

10,500 Btu/lb. = 23.1 million Btu/t = 6.77 MWh/t = $212.92 per tonne

12,200 Btu/lb. = 26.8 million Btu/t = 7.87 MWh/t = $247.51 per tonne

 

 

 

Who verified the energy content of Arterran's biofuel?

Three independent labs have verified the energy content of Arterran. PowerTech Labs, a subsidiary of BC Hydro, is the leading energy testing lab in Western Canada, Gwil Industries Britley Coal and Minerals Testing Division and SGS. The Gwil test was to confirm our biofuel as a binder for coal fines.

 

Are there any processes similar to Arterran’s?

 

We talk about wood pellets a lot. They are solid and they are a renewable biofuel. Fortunately or unfortunately that’s where the similarity ends. Industrial wood pellets have an energy content of 7,250 to 7,500 Btu per pound. Arterran is 10,000 to 12,000 Btu per pound.

 

The process of Torrefaction (Roasting) creates some similarities as far end product is concerned if wood is used as the feedstock. Torrefaction of wood can be described as a mild form of pyrolysis at temperatures typically ranging between 390°F and 600°F.

 

Pyrolysis is a thermochemical decomposition of organic material at elevated temperatures in the absence of oxygen. However like Arterran Biofuel, torrefaction leads to a dry product with no biological activity like rotting and a hydrophobic product resistant to moisture.

 

Torrefication produces a final product of 8,000 to 8,300 Btu per pound. 

 

Unfortunately Torrefied wood also requires the addition of binders to "glue" the pellets together. 

 

Torrefied is limited to wood as a feedstock

 

Feedstock Variety                                                           Arterran                               Torrefied

Forestry residue: wood chips and sawdust                         Yes                                        Yes

Animal manures and agricultural wastes                             Yes                                        No

Nuisance plants such as Water Hyacinth and Milfoil           Yes                                        No

Forestry waste including slash, bark and leaves                 Yes                                        No

Lawn and garden waste                                                       Yes                                        No

Fast food packaging, cardboard and paper                         Yes                                        No

Municipal Solid Wastes (+- 40% cellulosic material)           Yes                                        No

 

 

What other advantages does Arterran have vs. Wood Chips?

 

Arterran substantially reduces the moisture content of the feedstock used and increases the BTU value per ton. Arterran is dense, dry, water resistant, non-perishable, easily crushed and energy dense, reducing transportation cost per BTU.

 

Arterran’s increased density and lower moisture content allows it to be stored for long periods and if the Arterran is pelletized, its density is doubled, further reducing the cost of transport.

 

 

What other advantages does Arterran Pellets have vs. Coal?

 

When Arterran pellets are used in lieu of coal as a boiler fuel, significantly less ash is produced, and sulfur emissions are low. Further, Arterran’s energy content as measured in BTUs/lb, is comparable to coal. If used as a gasifier feed, Arterran pellets can be ground to a particle size similar to pulverized coal and can be fed into gasifiers designed for coal gasification without further modification.

 

 

Is Arterran Biofuel hydrophobic?

 

Arterran biofuel is hydrophobic.  Wood pellets are hygroscopic and must be protected from the elements, since any moisture becomes added weight and negatively affects the energy content.

 

Every percentage point of moisture negates an equal percentage of Btu’s. Excessive moisture also causes wood pellets to swell, break apart and become useless.

 

 

Does Arterran produce less the ash than coal?

 

Coal produces 6% to 15% toxic ash when burned. Arterran produces less than 2% when burned.

 

 

Does Arterran biofuel decompose and give off gasses?

 

No. As industrial wood pellets decompose, they off-gas Carbon Monoxide, Carbon Dioxide and Methane in enough quantity to pose a potentially fatal hazard to workers involved in handling and shipping. This off-gassing requires a number of air sampling and monitoring devices in the production facility, the warehouse, during shipping and at the end users facility. Arterran does not.

 

 

Does Arterran require special storage?

 

No. Some wood pellet storage facilities require inert gas systems to mitigate the heat produced from decomposition and prevent spontaneous combustion. These additional measures incur additional capital and operating costs.

 

 

Does Arterran Biofuel lower handling cost?

 

Arterrran Biofuel is significantly denser than wood pellets.

 

 

 

Whats the moisture content of Arterrran Biofuel?

 

Coal has a moisture content of 6% to 24%. Wood Pellets have a moisture content of 5% to 10%.
Arterran has a moisture content of 2% to 4%

 

 

 

Can Arterran lower operating costs?

 

Arterran biofuel is less expensive to store, less costly to grind.

 

 

 

What Feedstock’s can Arterran use to make biofuel?

 

Our process is not limited to wood as a feedstock.
Any material with a suitable amount of cellulose will work. 

 

Cellulose Content of availible feedstocks

 

Wood - 45.20%                           Soybean Hulls – 46.0%                   Forage Grass –    35.64% 

Sorghum Straw – 35.87%           Corn Stover – 38.0%                       MSW – +-40%                   

       

 

Municipal Solid Waste is 40% to 50% cellulosic material that is suitable as a feedstock for our process. Local, State, Provincial and Federal statistics estimate 500 to 600 kilograms of MSW per person per year. That equates to 190 to 240 kilograms of AR Biofuel per person per year.
