Solution Approach 2:
The invention extracts and eliminates the harmful combustion process and flue gas generation from the system by using electric resistance heating elements embedded in ceramic catalyst modules, separating the heating function from the catalytic reforming function
2Productivity
If conventional hydrogen production processes are used, then established production capacity is achieved, but operational flexibility and efficiency are limited
Solution Approach 1:
The invention introduces dynamic control capabilities through electric resistance heating elements that can be independently controlled, allowing rapid adjustment of temperature and process conditions to optimize for different operating scenarios, feedstocks, and product requirements
Solution Approach 2:
The invention segments the catalyst into modular ceramic modules with embedded heating elements, allowing independent control and optimization of different reaction zones, enabling flexible process configuration and rapid start-up/shutdown operations
3Temperature
If conventional heating methods are used in catalytic reforming, then high temperature conditions are achieved, but flue gas emissions and heat loss occur
Solution Approach 1:
The invention replaces the mechanical/chemical combustion heating system with an electric resistance heating system embedded directly in the catalyst modules, eliminating the need for external burners and flue gas management while providing direct, efficient heat transfer to the reaction zone
Solution Approach 2:
The invention nests the electric resistance heating elements within the ceramic catalyst modules themselves, creating a integrated structure where the heating function is embedded within the catalytic function, enabling direct heat transfer and eliminating heat loss to the environment
