Assessment of advanced coal gasification processes
Technical Report
·
OSTI ID:5385617
A technical assessment of the following advanced coal gasification processes is presented: high throughput gasification (HTG) process single stage high mass flux (HMF) process (CS/R) hydrogasification process and the catalytic coal gasification (CCG) process. Each process is evaluated for its potential to produce synthetic natural gas from a bituminous coal. Key similarities, differences, strengths, weaknesses, and potential improvements to each process are identified. The HTG and the HMF gasifiers share similarities with respect to: short residence time (SRT), high throughput rate, slagging, and syngas as the initial raw product gas. The CS/R hydrogasifier is also SRT, but is nonslagging and produces a raw gas high in methane content. The CCG gasifier is a long residence time, catalytic, fluidbed reactor producing all of the raw product methane in the gasifier.
