The increase in CO2/CH4 ratio is found to expand the coke removal zone.
Numerical modeling of workpiece temperature along with experimental measurement by a pyrometer is performed to determine the temperature at the material removal zone during LAM and to analyze the temperature gradient information to delineate the occurrence of cracking.
Secondly, the external positioning allows high temperature gradients between the heat removal zone and the active area resulting in a good adjustability of appropriate reformate conversion temperatures (e.g. 160 °C) and a more compact cell design.
Our observations of ant, spider, and bird behavior at these sites suggests that competitor removal did not deter predator foraging on plants with a 10 cm removal zone.
For this reason, this zone also has been called the "tree-removal zone".
Here we report the results of a systematic study aimed at determination of optimal conditions for chemical abrasion of single zircon grains to ensure complete removal of zones that were affected by Pb loss in a single high temperature leaching step.
They conclude that mass removal from source zones is ineffective unless a large fraction of the entrapped free-phase NAPL is removed.
If the longitudinal structure of cellulose I fibrils is as illustrated in Figure 2, with recurring regions of non-crystalline polymers along the fibril axis, preferential removal of these zones could result in an apparent increase in LFD.
The design of an effective groundwater remediation system involves the determination of the source zone characteristics and subsequent source zone removal.
