Gasification is a high temperature/pressure chemical process is used to convert a carbon feedstock in to CO and H2 for 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 CO2 capture 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.
