查询词典 sulfur bacterium

The δ^34S values of ore minerals vary slightly from -3.1‰ to +0.7‰ with an average value of -1.1‰ and the δ^34S values of the ore-bearing porphyries are -1.4‰ and -1.5‰, indicating that sulfur is mainly derived from the magma of porphyry.

Since H〓S and SO〓 adsorbed on TiO〓 could react with each other and TiO〓 is the medium of their electron transfer, thus SO〓 could not be adsorbed quite strong on the active site of TiO〓, which makes it more resistant to sulfating and increase the stability of catalyst. Finally, the model and mechanism of the reduction of SO〓 by NH〓 to elemental sulfur is advanced as follows: on the sulfide catalyst, ammonia is decomposed to N〓 and H〓, and H〓 reacts with SO〓 to form the intermedium of H〓S; then H〓S and SO〓 react as Claus reaction on TiO〓 catalyst.

反应系统中过量水蒸气的存在使催化剂表面某些活性位被水蒸气抑制使活性和选择性有较大幅度降低，但这种影响是可逆的，不会造成催化剂永久性中毒；另外当单质硫和水蒸气同时存在时，在〓催化剂上能够生成硫化氢和二氧化硫，而且由于硫化氢和二氧化硫化学吸附能力不同而导致它们的脱附顺序不同，硫化氢的生成温度总是低于二氧化硫的生成温度，说明过量水蒸气的存在会导致氧化物催化剂上逆克劳斯反应的发生；而在硫化物催化剂上几乎没有硫化氢和二氧化硫生成，说明硫化物催化剂能够抑制逆克劳斯反应的发生。
