Patent number: 7182796Abstract: The present invention provides an odorant suitable for use in fuel gases, such as liquefied natural gas (LNG), city gas, and LP gas, or methane gas, propane gas, butane gas and hydrogen gas. Preferably, the present invention provides a novel odorant that can also be used for fuel gases for fuel cells, including hydrogen gas. The odorant for fuel gases of the present invention has a perceptual threshold of 1 ppb or less, and includes a compound that has no sulfur atoms and no nitrogen atoms in its molecules. The odorant for fuel gases of the present invention is suitable for use in fuel cells that use hydrogen gas or other gases as a fuel.Type: GrantFiled: November 22, 2002Date of Patent: February 27, 2007Assignee: Soda Aromatic Co., Ltd.Inventor: Yutaka Kato
