Seasonally, we observed that while the timing of peak soil pCO2 was similar across the watershed, the amplitude of the pCO2 peak was higher in the deep soils due to more variable moisture content.
This technology, which have already been demonstrated and tested, allows treating feedstock with more than 80% moisture content and can lead to high SNG conversion efficiencies.
The corrosion rate is approximately constant in spite of increase of moisture content more than 40%.
Nitrification process becomes more important at low moisture content and low temperature.
Tests of relative difference indicated that soil moisture content was more stable under dry than under wet conditions.
Powders with lower moisture content were more hygroscopic, which is related to the greater water concentration gradient between the product and the surrounding air.
The VOPcPhO TiO2 (90 nm) nano-composite film is comprised of uniformly distributed voids which makes the surface more favorable for adsorption of moisture content from environment.
This suggests that lower moisture content is more desirable for generating less heat, but sod must be irrigated prior to harvest to provide adequate handling properties.
At the end of 200°C, the samples had lost about 17% of their initial weight which was more than the 11% moisture content, suggesting thermal evaporation and possibly onset of some initial thermal decomposition of some tobacco constituents [16,18,19].
More specifically, the residual soil moisture content (θr) was found to be the primary control on MRD, mainly due to the semi-arid climate that was simulated.
