請問在煤化工術語中，MTO是什么意思。請問，煤化工中說的MTP，是什么意思?。?/h2>

MTO甲醇制烯烴(Methanol To Olefin，MTO)是煤制烯烴工藝路線的核心技術，是將甲醇轉(zhuǎn)化為乙烯、丙烯的工藝。

MTO工藝開辟了由煤炭或天然氣生產(chǎn)基本有機化工原料的新工藝路線，是最有希望取代傳統(tǒng)的以石腦油為原料制取烯烴的路線，也是實現(xiàn)煤化工向石油化工延伸發(fā)展的有效途徑。乙烯、丙烯是重要的基礎有機化工原料，目前均產(chǎn)自石油路線，由于石油資源緊缺，已經(jīng)嚴重影響到下游的化工產(chǎn)業(yè)。我國的煤炭資源相對豐富，保有儲量超過1萬億噸，利用豐富的煤炭替代石油是一條適合我國國情的化工產(chǎn)業(yè)可持續(xù)發(fā)展道路，是國家能源安全的一個重大戰(zhàn)略課題。煤制烯烴技術是以煤炭為原料，經(jīng)煤氣化、合成氣制甲醇、甲醇制烯烴等工藝過程代替過去只能以石油為原料的烯烴及下游產(chǎn)品的煤炭清潔利用技術。MTP ，甲醇制丙烯簡稱為MTP?；萆こ蹋ㄖ袊┯邢薰臼菢I(yè)內(nèi)為數(shù)不多的集煤化工裝置工程設計、建設及項目管理、開 車及生產(chǎn)運營能力為一體的專業(yè)工程公司之一。承接大型煤化工裝置的工程建設，如：煤制烯烴（MTO）裝置、煤制丙烯（MTP）裝置，甲醇、二甲醚及合成氣裝置等，并提供相應的技術服務.

pa0什么意思？

烯烴其英文為：Poly Alpha Olefin ，縮寫是PAO，聚a烯烴PAO是合成基礎油中的一種，是由乙烯經(jīng)聚合反應制成α烯烴，再進一步經(jīng)聚合及氫化而制成。它是最常用的合成潤滑油基礎油，使用范圍最廣泛。
