Method for Measuring a Degree of Hydrogenation

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method and measurement device for determining the degree of hydrogenation (hydrogen content) in a liquid that serves as a hydrogen carrier, such as mixtures of dibenzyl toluene or benzyl toluene and their partially or fully hydrogenated forms. The technique works by measuring a physical property of the liquid (like density or optical refractive index), and then uses a known linear relationship between this property and the hydrogenation level to calculate the amount of hydrogen stored or releasable in the liquid. The device can also be integrated into a tank system, displaying available energy and supporting hydrogen storage and release operations.

Use CasesContent extracted from patent full text and abstract with AI.

• Monitoring hydrogen content in tanks storing liquid organic hydrogen carriers (LOHC) for stationary or mobile hydrogen storage systems.
• Enabling real-time measurement and optimization of hydrogen loading/unloading processes in chemical reactors or hydrogen refueling stations.
• Displaying remaining energy or hydrogen content in vehicles powered by hydrogen released from LOHC systems, supporting range estimation and energy management.
• Facilitating energy transaction measurements during refueling of LOHC-based hydrogen at tank stations.
• Enabling safety monitoring and process automation in industrial hydrogen logistics using LOHC technology.

BenefitsContent extracted from patent full text and abstract with AI.

• Provides a simple, rapid, and accurate way to determine hydrogen content in complex mixtures of liquid hydrogen carriers without requiring individual concentration measurements of all components.
• Allows for automation and continuous monitoring in tanks, reactors, and vehicles, improving operational efficiency and safety.
• Enables precise calculation of stored or releasable energy, supporting better energy management for vehicles and stationary systems.
• Reduces cost, complexity, and time compared to traditional chemical or spectroscopic analysis methods for hydrogen content determination.
• Compatible with existing liquid fuel logistics infrastructure since it utilizes liquid carriers amenable to standard pumps, tanks, and measurement tools.
