本論文は、代替炭素源（ACS）を利用した化学ビルディングブロックの脱化石燃料化における原料利用可能性の影響を評価する。ロッテルダム港の石油化学クラスターを対象に、多目的最適化モデルを用いて、無制限および制限付きの原料シナリオを分析。結果、原料が無制限の場合はプラスチック廃棄物の熱分解が有望だが、制約がある場合はACSと化石技術の併用が必要となり、脱化石燃料化の度合いが低下する。
English
This paper evaluates the impact of feedstock availability on defossilizing chemical building blocks using alternative carbon sources (ACS). A multi-objective optimization model of the Port of Rotterdam petrochemical cluster compares unlimited and limited feedstock scenarios. Results show that under unlimited feedstock, plastic waste pyrolysis is promising, but with constraints, a mix of ACS and fossil technologies is needed, reducing defossilization levels.

📄 Abstract（原文）
Alternative carbon sources (ACSs) such as CO 2, biomass, and plastic waste can be used to defossilize chemical building blocks (CBBs) such as methanol, olefins, and aromatics. While the existing literature estimates the quantities of ACSs to replace fossil fuel in specific processes, hubs, or areas, this work adds to the current state of the art by evaluating the impact of ACS feedstock availability on the portfolio of technologies that can be deployed to defossilize an existing petrochemical cluster. A superstructure-based multiobjective optimization model of the Port of Rotterdam was run with eight novel ACS-based processes to evaluate the impact of defossilizing CBB production. The paper explicitly evaluates the performance of the cluster using the following performance indicators: amount of feedstock use, byproduct production, CAPEX, electricity demand, water demand, and change in the minimum selling price of the products. Three cases are analyzed: the fossil-based cluster and two cases, one with unlimited and one with limited feedstock availability. The results show that if feedstocks are considered unlimited, plastic waste-based pyrolysis, methanol-to-olefin, and methanol-to-aromatics routes appear to be the most promising technologies. However, when feedstock constraints are included in the model, a combination of ACS and fossil-based technologies is required to meet product demand, and the level of defossilization significantly decreases. This research underscores the critical need to balance technological choices and realistic assessments of ACS feedstock availability to ensure a sustainable and economically viable transition of the chemical industry.
