1 國(guó)內(nèi)外煤化工發(fā)展概況
煤化工是以煤為原料,經(jīng)過(guò)化學(xué)加工使煤轉(zhuǎn)化為氣體、液體、固體燃料以及化學(xué)品的過(guò)程。從煤的加工過(guò)程分類(lèi),主要包括干餾(含煉焦和低溫干餾)、氣化、液化和合成化學(xué)品等。在煤化工發(fā)展歷程中,煉焦是應(yīng)用最早的工藝,并且至今仍然是化學(xué)工業(yè)的重要組成部分。煤的氣化在煤化工中占有重要地位,用于生產(chǎn)各種氣體燃料,是潔凈的能源,有利于環(huán)境保護(hù)。煤氣化生產(chǎn)的合成氣是合成液體燃料等多種產(chǎn)品的原料。煤直接液化,即煤高壓加氫液化,可以生產(chǎn)人造石油和化學(xué)產(chǎn)品。在石油資源短缺時(shí),煤的液化產(chǎn)品將替代目前的天然石油。
