Hematite (α-Fe2O3) has been proved to be a promising sorbent for mercury removal in various situations. The mercury removal performance of α-Fe2O3 was investigated using a simulated coal gasification syngas containing Hg0, N2, HCl, and/or H2S, a series of experiments were designed with HCl and H2S separately and both employed. For a better understanding in the interaction between HCl and H2S in mercury...
Removal of sulfur from petroleum improves the performance of refineries and reduces air pollution from fuel combustion. Biodesulfurization can selectively remove sulfur from petroleum, but improved biocatalysts are needed. This study illustrates a new approach to obtain improved desulfurization biocatalysts. A synthetic gene (Sulpeptide, S1) encoding high proportions of the sulfur containing amino...
This paper reports the characterization of successive extract fractions collected during the liquefaction in tetralin of a UK low-rank bituminous coal (Linby), by the use of size exclusion chromatography and u.v. absorption and u.v. fluorescence spectroscopies in a closely related manner. Successive liquefaction product fractions shift progressively to greater molecular masses with increasing extent...
