Now it will become cheaper to make second-generation biofuel for our cars
Date:2/24/2014

G Energy (denmark) have great focus on how to produce bioethanol from otherwise useless crop residues such as straw.

The use of bioethanol instead of gasoline reduces the CO2 emissions from cars and fossil fuel consumption.

HOW DID THE SCIENTISTS MAKE THE NEW ACID?

3 grams of ash from burned rice husk were mixed with 100 ml of caustic soda (NaOH) in a plastic container. The solution was stirred for 30 minutes at room temperature so that the ash content of the silicate was converted to sodium silicate. To the solution was added nitric acid to control its concentration, and then chlorosulfonic acid was added. When the pH approached 10, a white gel began to form. The addition of nitric acid was continued until the pH reached 3, where after the gel rested for 24 hours at room temperature. Then it was centrifuged six times with distilled water and finally the product was purified with acetone. The product was then dried at 110 degrees Celsius for 24 hours and grounded into a fine powder weighing 6.4 grams. This powder was RHSO3H.
