製油所の水素化脱硫（HDS）とガス精製が脱炭素化・持続可能燃料処理にどう寄与するかを、二次データの比較技術評価で分析した研究。最新のNiMo/CoMo触媒は硫黄除去99%の超低硫黄軽油を実現し、アミン系ガス精製はCO₂を90〜95%除去する。水素リサイクルと低炭素水素の導入により、製油所全体の排出量を30〜40%削減し得ることを示す。途上国では老朽インフラ・高硫黄原油・低炭素水素の調達制約が導入障壁となる。
English
A comparative technology review of how hydrodesulfurization (HDS) and amine gas sweetening can advance refinery decarbonization and sustainable fuel processing. Modern NiMo/CoMo catalysts achieve 99% sulfur removal and ultra-low-sulfur diesel, while amine sweetening captures 90–95% of CO₂. Integrating hydrogen recycling and low-carbon hydrogen could cut total refinery emissions by 30–40%, though aging infrastructure, high-sulfur crude, and limited low-carbon hydrogen constrain adoption in developing economies.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の製油所はSSBJ・有報でのScope 1/2開示と脱炭素燃料供給の両立が課題であり、水素管理とCCSを組み合わせたプロセス統合の視点は、国内精製業のトランジション計画やGX投資判断に示唆を与える。ただし途上国文脈が中心のため直接の制度対応論ではない。
In the global GX context
Refinery process decarbonization sits at the heart of Scope 1 abatement and transition planning under ISSB/CSRD, where fuel producers must disclose credible pathways. The paper's quantified integration of HDS, gas sweetening, and hydrogen management offers a technology-level reference for transition finance and low-carbon fuel standards, particularly for emerging-market refiners.

📄 Abstract（原文）
This work seeks to understand the contribution of hydrodesulfurization (HDS) and gas sweetening to advancing decarbonization of refineries and the processing of sustainable fuels. Specifically, the objectives focus on analyzing the mechanisms of HDS and gas sweetening, evaluating the innovations on catalysts and solvents, examining the strategies on the use of hydrogen, the capture of carbon, and proposing integrative strategies for the modernization of refineries in the developing world. Secondary data were sourced from peer-reviewed journals, refinery documents, patents, and publications from international bodies and were analyzed and modelled for comparative technological performance assessment. Findings showed that modern NiMo and CoMo catalysts yield ultra-low diesel and attain 99% Sulphur removal, while modern amine gas sweetening systems attain 90-95% CO₂ removal. Adding to decarbonization strategies the recycling and low-carbon hydrogen infusion of the process closing and decarbonization may be reduced by 30-40% of total emissions. Integration of hydrogen management, including recycling and low-carbon production, amplifies decarbonization outcomes, with potential emission reductions of 30–40%. Challenges in developing economies include aging infrastructure, high-sulfur crude input, and limited access to low-carbon hydrogen, which constrain technology adoption. Recommendations focus on catalyst and solvent modernization, hydrogen optimization, process integration, and policy frameworks that incentivize sustainable refinery operations. The study concludes that system-wide integration of HDS, gas sweetening, and hydrogen management is essential for achieving environmental compliance, ultra-clean fuel production, and alignment with national and international energy transition goals.
