The same UCR group has also demonstrated previously that carbon nanotube based catalysts can double the Pt utilization, potentially leading to a significant cost reduction for fuel cell production.

β¦ Synopsis
refineries. This could cost industry $55 M/y. The changes in the rules would update current EPA restrictions on emissions from refinery modifications. Refiners would have to add state-ofthe-art emissions control equipment on new or updated facilities. Refiners would also have to change certain work practices. The environmental benefits are put at $950 M/y. Over a five-year period, the changes would cut the combined emissions of particulates, sulfur dioxide and nitrogen oxide emissions by almost 56,000 tonne/y. Fluid catalytic crackers, fluid coking units, delayed coking units, process heaters and other fuel gas combustion devices or sulfur recovery plants would be affected.

carbon dioxide in the recycle gas. The production cost of the plant will be cut dramatically without affecting its production capacity. It is predicted that after the renovation, the plant's consumption of ethylene and oxygen will be decreased by over 10,000 tonne/y and over 40,000 tonne/y, respecti
