  • Mar 2017
During coal coking process a great deal of sulfurs are produced and are discarded to surroundings, which makes a lot of lands to be occupied and puts the environment to be polluted. In order to find multi-win production mode of coal coking for resources, surroundings and societies, carbon disulfide as an extracting agent was applied to extract sulf...

Context 1
... processes included mainly procedures such as pulverizing and screening of raw material, experimental solid leaching and filter as shown in Figure 1, in which solvent ran in a closed cycle. Key procedures of the process flow chart were extraction unit and filtration unit, in which particle size of raw material and post-treatment of filter liquor and filter cake were considered carefully to improve leaching rate and to decrease solvent losses and environmental damage. ...

This contribution investigates the low ignition temperature of carbon disulfide (CS2) with tubular flow reactor experiments. It explains the extreme flammability of CS2 with kinetic modelling entailing elementary reactions. The experiments are performed under dry conditions for an oxygen-fuel equivalence ratio of 0.7, 1.0 and 1.2 and for a temperat...
