Abstract: Abstract: In order to evaluate the effect of syngas cooling way of slurry feed gasification on the hydrogen production process, two processes of gasification for hydrogen with petcoke as the feedstock, petcoke water slurry+total quench+high mass ratio of water to dry gas (scheme Ⅰ) and petcoke water slurry+radiant syngas cooler+quench+low mass ratio of water to dry gas (scheme Ⅱ), were developed and simulated. The results showed that the quantity of steam produced by the two schemes are basically equal, while the proportion of high quality steam produced by the scheme Ⅱ is higher. The energy conversion efficiency of scheme Ⅱ and scheme Ⅰ are the same, which is 74%. The exergy efficiency of scheme Ⅱ (62%) is higher than that of scheme Ⅰ(61%). Thus, scheme Ⅱ is better than scheme Ⅰ and is more suitable for petcoke gasification for hydrogen in terms of energy analysis.
