Using statistical data from Statistics Bureau of Ningxia Hui Autonomous Region, the Grape Industry Development Bureau of Ningxia Hui Autonomous Region, and National Bureau of Statistics, ecosystem service value of grape industry at the eastern foot of Helan Mountain in Ningxia was evaluated from eight facets, i.e., food production, carbon fixation and oxygen release, air purification, soil conservation, water-holding, water conservation and efficiency, eco-tourism, and ecological poverty alleviation.

The catalytic performances for selective catalytic oxidation of H2S were further investigated, all catalysts exhibited high catalytic activities. Among them 5% Fe/Ce-Lap presented the best activity at 180 degreeC and the maximum sulfur yield was up to 96% due to the interaction between iron and cerium, which improved the redox ability of Fe3+ .

- - The review examines various selective catalytic oxidation technologies and catalysts for effectively removing H2S, a harmful byproduct from fluid catalytic cracking (FCC) processes.
- - Current technologies highlighted include Superclaus, Euroclaus, Clinsulf-Do, BSR/Hi-Activity, Selectox, and Modop, each with distinct features and use cases.
- - Catalysts discussed encompass carbon, supported SiC, zeolite, oxide, and pillared clay, with current focus shifting towards SiC due to its potential, while other systems like zeolite are seeing reduced interest and pillared clay remains in early research phases.
