利安德巴塞尔或在6年内建成世界规模化学品回收工厂

据ICIS网站3月9日消息 利安德巴赛尔周二表示，在未来五到六年内，利安德巴赛尔可能会开始建设一个世界级的化学品回收工厂。

利昂德巴塞尔首席执行官鲍勃?帕特尔表示：“我的希望是在未来五、六年内建设一个世界级的工厂。” 鲍勃?帕特尔在世界石油化工大会上发表了自己的看法。

利安德巴赛尔已委托在意大利费拉拉的一个中试规模的工厂，该工厂正在测试该公司与卡尔斯鲁厄理工学院（KIT）共同开发的MoReTec工艺技术。

这一过程依赖于一种催化剂，这种催化剂能够提供选择性，将废塑料加工成更接近石脑油的热解油。

化学或分子循环利用把废塑料分解成原料，裂解炉可以用来制造乙烯。公司可以将乙烯转化为聚乙烯（PE）。

相比之下，机械回收将废旧塑料再熔融成颗粒，再加工成新材料。机械回收可以减少温室气体的排放，而且不需要建造化工厂。

然而，塑料每次机械回收都会降解。经过足够的循环，塑料必须被丢弃或作为燃料燃烧。

机械回收也需要清洗和分类。有些塑料不易机械回收。

帕特尔指出了化学回收的其他优势，它可以在更大的规模上运作，并且可以生产美国监管机构联邦药物管理局（FD）批准的塑料。

帕特尔说：“归根结底，分子回收或将废物转化为原料是解决办法，因为这可以大规模进行。这种循环是游戏规则的改变者，我们可能还需要五年才能看到这种情况在全世界更加普及。”

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."
