Metal Contamination Slows Down Key Chemical Process that Makes Gasoline (1 of 6)

Caption

This Ffigure illustrates the analogy between the aging of apples and catalytic cracking particles. Metal deposition on aging FCC particles makes the internal macropore volume, although itself unobstructed, largely inaccessible. This material relates to a paper that appeared in the April 3, 2015, issue of Science, published by AAAS. The paper, by F. Meirer at Utrecht University in Utrecht, Netherlands, and colleagues was titled, "Life and death of a single catalytic cracking particle."
