By how much less does biodiesel pollute the air than regular gasoline and regular diesel?

Question

Please give in percent, or fractions if possible. Please give accurate answers. Provide the most info you are able to provide. Thank you! :)

Answer 1

Biodiesel helps somewhat, but not nearly as much as people seem to think. According to this data:

http://www.biodiesel.org/pdf_files/fuelf...

It reduces most pollutants by about a factor of 2 (not counting NOx which gets slightly worse).

Not sure on biodiesel vs gas.

Answer 2

All biofuels contribute to global warming on about the same level as traditional fuels through CO2 emissions. This is an inescapable aspect of the chemistry of combustion. The energy in diesel, gasoline, ethanol, and biodiesel is all in the form of hydrocarbon bonds. When these are broken, they form CO2.

Answer 3

The total emission is about the same. The biggest difference is in considering from where the CO2 portion of the emission comes. In petroleum based products all the carbon is fossil based and adds to the atmospheric load. With much more recent plant growth as a fuel source, the ethanol or biodiesel carbon being emitted isn't something that has been locked away for eons, but was removed from the atmosphere last growing season.

It isn't carbon neutral, because the processing from plant matter to fuel does use energy, but the biodiesel is about 75% carbon neutral. Since CO2 emissions are by far the greatest emission from combustion, I feel it should be considered a pollutant, and regulated.

A gallon of gasoline contains energy equal to 115,500 BTU. It will produce 10,874 grams of CO2 when the carbon in the fuel combines with the oxygen in the air. About 8 pounds of gasoline adds 24 pounds of fossil CO2.

A bit less than a gallon of diesel is also 115,500 BTU. It adds 10,963 g of fossil based CO2.

A bit more than a gallon of E85 is 115500 BTU and adds 7,747 g of fossil CO2.

A little more than a gallon of B100 biodiesel, also 115,500 BTU worth, adds 2,746 grams of fossil CO2, roughly 1/4 that of petrodiesel or gasoline.

Oh, Liquid hydrogen reformed from natural gas? 115,500 BTU emits 16,400 grams  of fossil CO2

Answer 4

They are the same. Diesel is no better or worse than gasoline. But diesel engines are more efficient, so from that point of view diesel could be said to be cleaner because less of it is needed to produce the same amount of power. Gasoline engines are up to 38% efficient and diesel engines are about 59% efficient, ideally.

Answer 5

I currently run ethanol (corn alcohol) in a 1999 Dodge 3500 truck. But all Cummins engines were modified from the factory to run on BioD since around 1992 without any modification.

when i go in for inspection and they hook up there little exhaust computer, the readings show about an 80% drop.

Most vehicles are already equipped to run on Alternative Energy. In fact you’re probably even driving one right now and didn’t even know it. Go to www agua-luna com for a list of this vehicles

The following are a couple types of products to make ethanol easily. There are however many materials one can use including sugar cane, corn, wood, etc. The information was cut directly from a guide I offer at www agua-luna com, it is complete but if anyone’s interested in other types of foods to use or a more specific step by step of the process, including building your own still legally, visit www agua-luna com

"THE usual sources of raw material for alcohol Ethanol production from starch are cereal grains such as corn, wheat, rye, barley, milo (sorghum grains), rice, etc. Other types of starch are available from potatoes of all kinds, Jerusalem artichokes, and other high-starch vegetables. Starch conversion is the standard method of production and the one we will discuss here.

It is possible, however, to make alcohol from sugar-producing plants (saccharine material) such as sugar beets, sugarcane, fruits, and others. These substances need no milling (as do grains), but they do require some kind of grinding or squeezing process. Rapid, efficient fermentation of these sugars has not been as well explored as the process using starch.

A third source of fermentables is cellulose, as found in wood and waste sulphite liquor. This more complex process requires the use of acids to reduce the material to wood sugars. Consequently, most do-it-yourselfers should stick to either starch or sugar.

MILLING

All grains must be ground before mashing to expose the starch granules and help them remain in suspension in a water solution. The grain should be ground into a meal -- not a flour! -- that will pass a 20-mesh screen. On a hammermill, however, a 3/16" screen will suffice.

Potatoes and similar high-moisture starch crops should be sliced or finely chopped. Since potato starch granules are large and easily ruptured, it isn't necessary to maintain the hard rapid boil which is required of the tougher, dryer "flinty" starches found in grains.

CONVERSION WITH ENZYMES

For small batches (5 bushels or less), fill the cooker with water (30 gallons per bushel), and add the meal slowly, to prevent lumps from forming. (When, cooking with steam, or at higher temperatures, it is possible to save energy by using less water at the beginning. But for the "small batcher" with an ordinary cooking apparatus, the most complete conversion is obtained by using the full amount of water right from the start to encourage a rapid rolling boil.)

Next, add 3 measuring spoons -- as provided -- per bushel of Alpha Amylase Enzyme (mixed in water) to the mixture and raise the temperature of the mash to 170 deg F (77 deg C), the optimum working environment for the enzyme. Hold the solution at that temperature for 15 minutes while agitating it vigorously.

At this point all the starch available at 170 deg F has been converted to dextrins, so it's time to raise the temperature of the mash to the boiling point. The concoction should be liquid enough to roll at its own rate -- if not, add 2 to 3 gallons of water. Hold the boil for 30 minutes to complete the liquefaction stage. All the starches are now in solution.

Now reduce the temperature to 170 deg F, using the cooling coil, and add 3 more measuring spoons per bushel of Alpha Amylase Enzyme (mixed in water). After 30 minutes of agitation at this temperature, all the previously released starches will have been reduced to dextrins, thereby completing primary conversion.

During secondary conversion the dextrins are further reduced to simple sugars (maltose and glucose) by the beta, or -- to be more exact -- glucoamylase enzymes. You need Alpha Amylase Enzyme and the yeast necessary to carry out secondary conversion and proper fermentation simultaneously, you can add 6 measuring spoons per bushel of the fermentation powder (mixed in water) as soon as you've brought the temperature down to 85 deg F (29 deg C) using the cooling coils."

Hope this helped, feel free to contact me personally if you have any questions if you’d like assistance in making your first self sufficient steps, I’m willing to walk you step by step threw the process. I’ve written several how-to DIY guides available at  www agua-luna com on the subject. I also offer online and on-site workshops, seminars and internships to help others help the environment.

Answer 6

If they are doing the same work it will produce the same CO2. The idea for bio diesel is if the Arabs cut off our oil we could get something to run.
