The researchers found that reducing the amount of KOH used by at least 50%, with a sludge-to-KOH ratio of 3:1 at a maximum temperature of 800 °C (1,472 °F) was optimal, producing a yield of 0.63 ...

The new technique, called the activated magnetic sludge process, was described today to scientists gathered in New Orleans for the weeklong 225th national meeting of the American Chemical Society ...
