Sulfur energy from

What is the minimum energy required to synthesize sulfur dioxide from sulfuric acid ... [Pg.122]

Thus, sulfur extrusion from the twisted naphtho[3,4-c/]thiepin is rapid, because in this case less energy is required to form the thianorcaradiene isomer than for a total loss of aromaticity. [Pg.66]

The higher strain energy in thiirene dioxides (19) compared to thiirane dioxides (17) is obvious. Yet, the elimination of sulfur dioxide from the latter is significantly faster than one would expect for a thermally allowed concerted process. Consequently, either aromatic-type conjugative stabilization effects are operative in thiirene dioxides2,12 or the relative ease of S02 elimination reflects the relative thermodynamic stability of the (diradical )99 intermediates involved in the nonconcerted stepwise elimination process. [Pg.400]

Penn State University Researchers Discover Inexpensive Way to Clean Up Sulfur Dioxide from Coal Plants. U.S. Department of Energy, National Energy Technology Laboratory, http //www.netl.doe.gov/newsroom/media rel/mr pennst.html... [Pg.48]

CNG [Consolidated Natural Gas] A process for removing acid gases from natural gas and syngas, using supercritical carbon dioxide. Under development since 1973 by the Consolidated Natural Gas Research Company with assistance from the U.S. Department of Energy and Helipump Corporation. Liquid carbon dioxide is first used to extract the sulfur compounds. Crystallization at the triple point separates these sulfur compounds from the... [Pg.67]

The scheme (Fig. 15.1) thus explained the production of both sulfate and sulfur in equimolar amounts from thiosulfate oxidation. In showing adenylylsulfate as an intermediate, it also provided a feasible route for the conservation of energy from sulfite oxidation by a substrate-level phosphorylation mechanism, in which ADP sulfurylase and adenylate kinase give rise to ATP ... [Pg.208]
