Comet工艺使用碎煤和粉矿作原料,其中碎煤中混有脱硫用的少量熟石灰或生石灰,碎煤与粉矿以薄层形式交替铺设,并连续送入转底炉。将这些原料快速升温至1200℃,二氧化碳和水将会与煤中的碳反应生成一氧化
The Comet process uses crushed coal and fines as raw materials, wherein the crushed coal is mixed with a small amount of slaked lime or quick lime for desulfurization. The crushed coal and fines are alternately laid in a thin layer and continuously fed into a rotary hearth furnace. The rapid heating of these raw materials to 1200 ℃, carbon dioxide and water will react with carbon in coal to form a monoxide
