佑護德爾托拉王國的寶帶被偷走，上面鑲嵌的7顆寶石被藏在了德爾托拉最黑暗恐怖的地方。沒有了寶帶的佑護，邪惡勢力暗影領(lǐng)主輕而易舉攻占了德爾托拉王國。年僅16歲的里夫面臨人生最大的挑戰(zhàn)，他必須去那些黑暗恐怖之地找回7顆寶石：黃寶石、紅寶石、貓眼石、天青石、綠寶石、紫水晶和鉆石——當(dāng)它們鑲嵌在德爾托拉寶帶上時，不但能庇佑后人登上德爾托拉的王位，還能保護人民免受暗影領(lǐng)主的殘酷壓迫。本書是“拯救德爾托拉”系列的第三部。雖然里夫、巴爾達和茉莉三人志趣并不相投，但經(jīng)過之前的磨合變得越來越有默契�，F(xiàn)在他們已經(jīng)成功找到了黃寶

Gasification process
Coal undergoes a series of chemical and physical changes in a gasification process. At drying stage when coal is heated at temperature higher than 100 ℃, most of the moisture is driven out. At devolatilization stage when coal temperature is increased to 500 ℃, significant devolatilization begins. More volatile materials are released at this stage. Liable bonds between the aromatic clusters in coal structure are cleaved, generating much smaller fragments. Fragments with low molecular weights will vaporize and escape from the coal particle to constitute light gases and tar. At gasification stage when coal temperature is higher than 900 ℃, maximum volatile yield occurs. More gas products were produced in the presence of CO, CO2, CH4, H2 and H2O. The yield and composition of volatile compounds depend on the heating rate and final temperature. Volatile yield at rapid-heating rates is normally 20-40% higher than that at slow-heating rates.
Gasifier
According to the fluidization regime, coal gasifiers are generally classified as moving bed, fluidized bed and entrained flow bed.
