New olefin production routes—A review of defossilised supply chain technologies with regards to surfactant production

With “defossilisation” at the core of many sustainability goals within industry, exploration new synthesis routes to chemicals has never been more vital. As part their Clean Futures initiative, Unilever Home Care published Carbon Rainbow, a scheme which categorizes chemical sources into different “colors,” depending on derivation. One Rainbow is phase out non-renewable “black” carbon from supply chains by 2030. This complements looks toward Net-Zero impact all products cradle-to-shelf scope 2039. Given substantial contributions atmospheric CO 2 emissions production and use conventional surfactants, this paper reviews methods form Linear Alkylbenzene Sulfonate (LAS) through means look utilize Rainbow-categorized outside traditional fossil sources. The focus when reviewing each method overall defossilization LAS process. inventories defossilised collated research will ultimately provide backbone for future study assessment screening. Through literature search technological overview, construction tree diagram showing LAS-appropriate olefins accomplished, illustrating breadth technologies available that share common goal defossilization. expanse works well as options necessary companies, though also resulting in vast array consider assess before pursuing optimum route. In total, 19 were reviewed, forming map containing 27 chain feedstock olefins. therefore shows need short-form screening order green-light are suitable long-form any process adopted.
