4. Analysis of Ash and Minerals . 4.1 Introduction. The "ash content" is a measure of the total amount of minerals present within a food, whereas the "mineral content" is a measure of the amount of specific inorganic components present within a food, such as Ca, Na, K and Cl.Determination of the ash and mineral content of foods is important for a number of reasons:

C/N Ratio - CORNELL Composting

C/N Ratio Tom Richard and Nancy Trautmann. Once you have calculated the moisture content of your compost mixture, the other important calculation is the carbon-to-nitrogen ratio (C/N). Grass clippings and other green vegetation tend to have a higher proportion of nitrogen (and therefore a lower C/N ratio) than brown vegetation such as dried leaves or wood chips.

Sieving and Acid Washing as a Pretreatment to Fast ...

May 22, 2019· In this work, ash reduction in biomass pyrolysis oil via sieving the fines portion of a hog fuel as well as washing the fractionated hog fuel with nitric acid was investigated prior to the conversion in CanmetENERGY-Ottawa's 5–10 kg/h fast pyrolysis system. It was found that sieving the material was much less influential on the liquid yield ...

• The solids load of 23.2 remains in the final product as ash. Similarly, in the case of process b, the solids load in the final product becomes 22.7 instead of 23.2 in process a. Moreover, a digestion gas equivalent of 39.5 is gained, which in turn is a source of energy.

The Equivalence Ratio: The Key To Understanding Pyrolysis ...

We find that on a dry ash free basis most "biomass" falls in a narrow range of composition. In our calculations the "carbon ratio formula" for typical biomass (dry, ash free basis) was taken to be CH1.4O0.6. The high heating value for this composition is 22.2 kJ/g (9550 Btu/lb) and the low heating value is 21.0 kJ/g (8987 Btu/lb).

Pool pH Calculator

Check pool pH levels often. Pool water pH is one of the best measures of balanced pool water. The pH of a human tear is 7.5 so the ideal range for best swimmer comfort is between 7.4 - 7.6 but 7.2 - 7.8 is considered an acceptable pool water range. Maintaining proper pH levels is essential for swimmer comfort, protection of pool equipment and effectiveness of the chlorine.
