The gasification process of coal oil water (COW) slurry in new-type coal water slurry(CWS) gasification furnace was studied with numerical simulation method. The temperature and concentration fields were obtained for the gasification furnace. The simulated results showed that the gasification effect of the new-type coal water slurry gasification is better than the common coal water slurry gasification. In the new-type gasification furnace, the average temperature is slightly increased and the carbon translative ratio is increased by 1.81%. The effective component (CO+H2) in coal gas at the outlet of the furnace is increased by 10.58%, and the concentration of CO2and H2O is greatly decreased. The H2O dissolution ratio is greatly increased and the gasification effect is obviously better that that of the common coal water slurry.

A new type of graft copolymer, sulfonated humic acid-acrylic acid resin (SHA), was synthesized and developed as dispersant for highly-loaded coal water slurry (CWS) from Chinese Binchang coal. In this study, The formulation, stability and rheology of the slurry with SHA were investigated. The experimental results show that SHA can reduce effectively CWS viscosity at low dosage, and that the CWS with SHA has excellent stability within 48 h and exhibits shear-thinning apparent viscosity/shear rate behavior. Based on the above, SHA is a promising dispersant for highly-loaded CWS in the practical use in industry.
