Abstract:
Provided is a desulfurization process using a combination of a suspension bed and a fixed bed, comprising mixing the desulfurization slurry with a hydrogen sulfide containing gas to obtain a first mixture, and passing the first mixture into a suspension bed reactor from bottom to top, with controlling the first mixture to have a dwell time of 5-60 minutes in the reactor to allow they contact and react sufficiently with each other; subjecting a second mixture obtained by the reaction to gas liquid separation to produce a gas phase, feeding the gas phase into a fixed bed reactor for carrying out a second desulfurization to obtain a purified gas. The process of the present invention may reduce the sulfur content in the hydrogen sulfide containing gas from 2.4-140 g/Nm 3  to 50 ppm or less by using a suspension bed, and further reduce the sulfur content to less than 10 ppm in conjunction with a fixed bed. The invention achieves high efficient desulfurization by combining the suspension bed with the fixed bed connected in series. The process of the present invention is simple and reasonable, with high desulfurization efficiency, simple equipment, little occupation of land and low investment, which is very suitable for industrial promotion.

Claim (Index 4):
The desulfurization process of  claim 1 , wherein, the desulfurization slurry has a desulfurizer concentration of 1-5 wt %.
