LOHCHub | 液体有機水素キャリア技術仕様＆永久炭素除去エンジニアリング
ジベンジルトルエン等の液体キャリアを用いた常温常圧での安全な緑色水素タンカー海上輸送、バイオマス発電・パルプ工場排煙からのバイオ起源CO2回収(BECCS/BiCRS)、およびEU CRCF基準に基づく炭素隔離。 (Liquid Organic Hydrogen Carriers, Catalytic Hydrogenation/Dehydrogenation Loops & Green H2 Logistics).
Operational Chemical Loops & Carbon Sinks
- 01. Catalytic Hydrogenation & Loading: Green hydrogen from water electrolyzers reacted with lean carrier (H0-DBT) at 140-180°C and 30-50 bar. Stores ~6.2 wt% H2 with exothermic heat recovery. (Process Flow: Electrolyzer H2 (30 bar) -> Trickle-Bed Reactor -> Ru/Al2O3 Catalyst Bed -> Liquid H18-DBT -> Ambient Bulk Tanks)
- 02. Ambient Fleet Logistics & Bunkering: Transport of fully hydrogenated carrier (H18-DBT) at room temperature and 1 atm using standard IMO Type II chemical tankers and railcars with zero boil-off loss. (Process Flow: Port Marine Loading Arm -> Handysize Chemical Tanker -> Oceanic Transit (Ambient 1 atm) -> Offload Terminal Buffer)
- 03. Endothermic Dehydrogenation & Release: Endothermic dehydrogenation of H18-DBT at 280-320°C over Pt/Al2O3 catalyst. Releases pure hydrogen for fuel cells via PSA, recovering lean H0-DBT for return cycling. (Process Flow: Liquid H18-DBT Feed -> Microchannel Reactor (Pt/Al2O3, 300°C) -> PSA Separator -> ISO 14687 Grade D H2 -> Lean H0-DBT Recycle)
- 04. Biogenic Carbon Removal (BECCS/BiCRS): Capture of point-source biogenic CO2 from biomass plants, dense-phase supercritical liquefaction at 100+ bar, isotopic 14C verification, and permanent basalt/saline mineralization. (Process Flow: Biomass Flue Gas -> Piperazine Amine Scrubber -> Supercritical Compression (120 bar) -> Deep Saline Aquifer Mineralization)
Process Engineering Layers & Safety Envelopes
- Layer 1: Exothermic Catalytic Hydrogenation & Upstream Ingress: Multi-tubular trickle-bed reactors packing ruthenium on gamma-alumina catalysts (Ru/Al2O3). Hydrogenates lean aromatic carrier molecules up to 99.4% saturation degree with active heat integration.
- Layer 2: Ambient Liquid Logistics, Chemical Tankers & Intermodal Terminals: Liquid carrier storage utilizing standard atmospheric carbon-steel and stainless-steel tanks. Compatible with conventional bunkering arms, ISO tank railcars, and IMO Type II chemical tankers without cryogenic insulation.
- Layer 3: Endothermic Release, Catalyst Bed & Pressure Swing Adsorption: Microchannel and shell-and-tube reactors packing platinum catalysts (Pt/Al2O3). Industrial waste heat or fuel cell thermal exhaust supplies 65 kJ/mol H2 endothermic enthalpy, releasing high-purity hydrogen.
- Layer 4: Biogenic Carbon Dioxide Removal (BECCS/BiCRS) & CRCF Compliance: Point-source carbon capture from biogenic flue streams using advanced amine and enzymatic absorbents. Supercritical dense-phase pipeline transport and verified mineralization in basalt or deep saline aquifers under EU CRCF.
