Gasification is a high temperature/pressure chemical process is used to convert a carbon feedstock in to CO and H2for use in power generation and the production of chemicals. It is also a source of hydrogen. Gasifiers are processing vessels containing high temperatures and pressures. They are also being considered as a critical component of advanced power generation technologies that target near zero emissions because they facilitate efficient CO2capture for storage or reuse. During gasification, impurities in the carbon feedstock liquify, forming a slag that attacks the refractory liner used to protect the high-pressure containment shell where gasification occurs, resulting in significant wear, reduced service life, and replacement costs. This technology can provide a porous high chromia refractory brick for gasifier environments where slag penetration is mitigated through use of carbon arranged in a manner compatible with the high chromium content of the refractory brick, reducing significant decreases in material performance.
