Climate change in Washington related emissions are the dominant source of GHG emissions and have increased from 61.2 MMT CO-equivalent (CO-e) in 1990 (excluding residual fuel for transportation) to 74.6 MMT CO-e in 2004, while their share has increased from 79% of total emissions to 85% over the past fourteen years. Carbon dioxide is the dominant GHG followed by methane, nitrous oxide, perfluorocarbon and sulfur hexafluoride. Non-energy industrial global greenhouse gas emissions have lowered from 14% to 9%, mainly due to reduced emissions from aluminum production. This has been the result of two key elements: process changes that reduced CO and PFC emissions per
Carbon dioxide reforming the commercialization of this process is that the hydrogen that is produced tends to react with the carbon dioxide. For example, the following reaction typically proceeds with a lower activation energy than the dry reforming reaction itself: Typical catalysts are noble metals, Ni or Ni alloys. In addition, a group of researchers in China investigated the use of activated carbon as an alternative catalyst. Carbon dioxide reforming Carbon dioxide reformation (also known as dry reformation) is a method of producing synthesis gas (mixtures of hydrogen and carbon monoxide) from the reaction of carbon dioxide with hydrocarbons such as methane. Synthesis
