The y axis is labeled carbon dioxide concentration in parts per million. The y axis begins at 175 and is marked at intervals of 225, 275, 325 and 375. The line on the graph rises and falls between 400,00 and 100,000 years on the x axis, with the highest peaks reached over that time were near 275 on the y axis and the lowest peaks near 175 …

The surface area of carbon has two functions. First, increased surface area with the same sulfur content (80%) in the composite means sulfur distribution among the high surface area carbon is more dilute, e.g. thinner coating on the carbon surfaces. Therefore, compared with low surface area AB and HCNS, the utilization rate of sulfur is …
