Title:

METHOD FOR GASIFYING TIRE CHIP

Document Type and Number:

Japanese Patent JP3676390

Kind Code:

B2

Abstract:

PURPOSE: To gasify tire chips into a gas which does not contain impurities such as a fine coal powder and has a stable calorific value while reducing the amt. of a waste produced, such as char.
CONSTITUTION: Tire chips are gasified by using a packed-bed gasifier having a feed preheating zone, a dry distillation zone, a water-gas producing zone, a combustion zone, and an ash storage zone installed in this order from the upper side. The gasification is done by filling a homogeneous mixture comprising 100 pts.wt. tire chips and 5-200 pts.wt. at least one solid carbonaceous fuel selected from coke, coal, and oil coke into the feed preheating zone to form a packed bed, passing the packed bed continuously or intermittently through all the subsequent treating zones, simultaneously supplying continuously or intermittently a mixture of steam and air to the water-gas producing zone and air to the combustion zone, and taking out a distillation gas and a fuel gas mainly comprising water gas.
