PRODUCT INTRO

A new fixed-bed catalyst-evaluation platform built around the Joule-heating effect, with in-house control software and algorithms. By passing current directly through the conductive carbon felt holding the catalyst, or through a conductive catalyst bed, Joule heat is generated inside the bed, achieving second-scale rapid heating and delivering heat directly into the reaction zone. It also integrates an independent electric-furnace mode that can run separately from or in comparison with the Joule-heating mode on the same reaction platform. It shares the multi-channel feed and control architecture of the tabletop/vertical fixed-bed reactors, with four gas channels and one liquid channel as standard. Suited to catalytic studies that require rapid heat input or temperature-program switching and are compatible with the electrode and reaction-tube materials, such as high-temperature endothermic catalysis in green-hydrogen production and pyrolysis of plastics and biomass.

PRODUCT ADVANTAGES

• Second-scale rapid heating — Joule heat is generated inside the conductive bed, shortening the heat-transfer path for fast response; suited to transient kinetics and rapid catalyst screening
• Same-bed dual heating modes — Joule heating and an independent electric furnace can heat the same bed, enabling comparison of internal vs. external heating without disassembly
• Isolated non-intrusive wall-adjacent thermometry — the thermocouple sits against the outer wall of the quartz liner, electrically isolated from the powered bed, avoiding heating-current interference and without piercing the bed
• In-house control software — the JouleReact software and control algorithms are developed in-house, with power closed-loop, predictive-temperature control and per-loading self-tuning that adapts to different catalysts and suppresses overshoot
• Multi-level safety interlocks and full logging — software multi-level safety interlocks plus power-supply hardware over-voltage/over-current protection, with per-second CSV logging
• Replaceable electrode feedthrough — graphite electrode in the hot zone, PTFE insulating liner and standard SS316 ferrule fitting in the low-temperature zone, allowing repeated disassembly and consumable replacement
• Adjustable bed height — the catalyst bed height can be adjusted according to loading amount and experimental needs
