【摘要】：近10年來(lái),中國(guó)石化石油化工科學(xué)研究院(RIPP)在開(kāi)發(fā)新一代催化裂化技術(shù),包括生產(chǎn)清潔燃料、加工劣質(zhì)原料、生產(chǎn)化工原料等的催化裂化技術(shù)過(guò)程中,在反應(yīng)化學(xué)基礎(chǔ)理論方面獲得了諸多新認(rèn)識(shí),如重油催化裂解鏈的引發(fā)反應(yīng)路徑具有多元性,大分子烴經(jīng)五配位正碳離子引發(fā)鏈反應(yīng)將導(dǎo)致大量干氣的生成;正碳離子的異構(gòu)化反應(yīng)是影響丙烯生成的重要反應(yīng)路徑;丙烯是重油一次裂解反應(yīng)和汽油中烯烴二次裂解反應(yīng)的共同作用結(jié)果;乙烯的生成來(lái)自自由基反應(yīng)和正碳離子反應(yīng)等。概述了在新認(rèn)識(shí)指導(dǎo)下形成的原始性創(chuàng)新技術(shù)及其工業(yè)實(shí)踐結(jié)果,并展望了催化裂化技術(shù)的發(fā)展方向。
[Abstract]:In the past 10 years, RIPP has been developing a new generation of FCC technologies, including the production of clean fuels, the processing of inferior feedstocks and the production of chemical feedstocks. In the basic theory of reaction chemistry, many new ideas have been obtained. For example, the initiation path of catalytic cracking chain of heavy oil is diverse, and the reaction of macromolecular hydrocarbon through five-coordinated positive carbon ion initiation chain will lead to the formation of a large amount of dry gas. The isomerization of cationic ions is an important reaction path affecting the formation of propylene, and propylene is the result of both the primary cracking of heavy oil and the secondary cracking of olefin in gasoline. The production of ethylene comes from free radical reaction and positive carbon ion reaction. The original innovative technology formed under the guidance of new knowledge and its industrial practice results are summarized, and the development trend of catalytic cracking technology is prospected.
