???? 據(jù)ICIS網站3月9日消息 利安德巴賽爾周二表示，在未來五到六年內，利安德巴賽爾可能會開始建設一個世界級的化學品回收工廠。

????利昂德巴塞爾首席執(zhí)行官鮑勃?帕特爾表示：“我的希望是在未來五、六年內建設一個世界級的工廠。” 鮑勃?帕特爾在世界石油化工大會上發(fā)表了自己的看法。

????利安德巴賽爾已委托在意大利費拉拉的一個中試規(guī)模的工廠，該工廠正在測試該公司與卡爾斯魯厄理工學院（KIT）共同開發(fā)的MoReTec工藝技術。

????這一過程依賴于一種催化劑，這種催化劑能夠提供選擇性，將廢塑料加工成更接近石腦油的熱解油。

????化學或分子循環(huán)利用把廢塑料分解成原料，裂解爐可以用來制造乙烯。公司可以將乙烯轉化為聚乙烯（PE）。

????相比之下，機械回收將廢舊塑料再熔融成顆粒，再加工成新材料。機械回收可以減少溫室氣體的排放，而且不需要建造化工廠。

????然而，塑料每次機械回收都會降解。經過足夠的循環(huán)，塑料必須被丟棄或作為燃料燃燒。

????機械回收也需要清洗和分類。有些塑料不易機械回收。

????帕特爾指出了化學回收的其他優(yōu)勢，它可以在更大的規(guī)模上運作，并且可以生產美國監(jiān)管機構聯(lián)邦藥物管理局（FD）批準的塑料。

????帕特爾說：“歸根結底，分子回收或將廢物轉化為原料是解決辦法，因為這可以大規(guī)模進行。這種循環(huán)是游戲規(guī)則的改變者，我們可能還需要五年才能看到這種情況在全世界更加普及。”

????Lyondellbasell may build world-scale chem-recycling unit in 6 years

????Lyondellbasell could start construction on a world-scale chemical recycling plant in the next five to six years, the CEO said on Tuesday.

????"My hope is over the next five, six years, we're in construction of a world-scale unit," said Bob Patel, Lyondellbasell CEO. He made his comments during the World Petrochemical Conference by IHS Markit.

????Lyondellbasell had commissioned a pilot-scale plant in Ferrara, Italy, that is testing the company's MoReTec process technology that it developed with the Karlsruhe Institute of Technology (KIT).

????The process relies on a catalyst that provides selectivity to process the waste plastics into a pyrolysis oil closer to naphtha.

????Chemical or molecular recycling breaks down waste plastic into feedstock that crackers can use to make ethylene. Companies can then convert the ethylene into polyethylene (PE).

????By contrast, mechanical recycling remelts waste plastic into pellets that can be re-processed into new materials. Mechanical recycling can result in fewer greenhouse gas emissions and it does not require the expense of building chemical plants.

????However, plastic degrades each time it is mechanically recycled. After enough cycles, the plastic has to be discarded or burned as fuel.

????Mechanical recycling also requires washing and sorting. Some plastic is too filthy for mechanical recycle.

????Patel noted other advantages of chemical recycling. It can operate on larger scales and it can produce plastic approved by the Federal Drug Administration (FD), a US regulator.

????"Ultimately, molecular recycling or turning waste into feedstock is the answer because it can be done at scale," Patel said. "That loop of circularity is a game changer. We're probably five years away from seeing this being more prevalent around the world."
