【文章內(nèi)容簡介】 ? 間接液化能量轉(zhuǎn)換率低 ? 最重要的是在經(jīng)濟上無法和石油煉制競爭 ? 煤氣化多聯(lián)產(chǎn)系統(tǒng) 是較好選擇 ?the quality of fuel is bad (direct liquefaction) ?The energy transformation ratio is low (indirect liquefaction), ?economically unfeasible ?The polygeneration is a good option 增加溫室氣體減排成本 Increase the costs of reducing GHG emissions ? 我國在 1995年所排放的 CO2 總量達 30億噸，占世界總排放量的% ? 我國的 CO2 排放遲早會受到限制 ? 常規(guī)技術(shù)的燃煤電站減排 CO2 非常困難 ? The CO2 emission of China in 1995 is % of total emission in the world ? The CO2 emission will be limited sooner or later. ? mitigating greenhouse gas (GHG) emissions in conventional coal power plant will lead to high cost.

The pollution of coal power generation will be lower down to the level of naturalgas fired bined cycle power plants. ? Polygeneration can provide clean transportation fuels, which are much better than petroleum derived gasoline and diesel fuels from them the point of view emission, thus, to reduce the petroleum import significantly. ? Not like “ pure” integrated gasification bined cycle (IGCC), polygeneration based on coal gasification can make the clean power generation economically petitive. ? Produce DME (similar as LPG), solve the distribution energy serve problem in rural area. 煤氣化多聯(lián)產(chǎn)的技術(shù)優(yōu)勢（二） The advantage of modernization coal utilization （ 2） ? 將會使我國汽車工業(yè)、發(fā)動機制造業(yè)走出具有中國特色的道路，實現(xiàn)跨越式前進 ? 清潔地利用高硫煤，解決相關(guān)問題。 ? 為低成本實現(xiàn) CO2減排提供可能 ? A very prospective opportunity for Chinese automobile industry to have own intellectual property and to realize the leapfrog movement forward. ? Use the high sulfur coal cleanly. ? Provide the probability of low cost mitigation of CO2 in the long term. 煤炭現(xiàn)代化的前景 Vision for Modernized Coal E n e r g y C a r r i e r sE l e c t r i c i t yS t e a mT o w n g a sM e t h a n o l / g a s o l i n e b l e n dF T / D i e s e
