Dual-Reactor Evaluation Unit

The XINYU HUACHUANG Dual-Reactor Evaluation Unit is a high-efficiency laboratory system designed to accelerate catalyst screening and process optimization. Featuring two independent parallel reaction channels, it allows simultaneous evaluation of different catalysts or varying operating conditions under identical parameters. Equipped with precise mass flow controllers, multi-zone heating, and intelligent PLC automation, this unit significantly reduces experimental cycles while ensuring highly reproducible, comparable data for industrial scale-up.

Working Principle

● Core Mechanism: Dual-Reactor Evaluation Unit operates on a parallel plug-flow principle. Reactants are precisely metered via mass flow controllers and distributed into two independent reactor tubes. The gas-solid or liquid-solid reactions occur within the fixed catalyst beds, and products are analyzed online to evaluate conversion rates and selectivity.

● Reactor Materials: To accommodate diverse chemical environments, we offer premium reactor materials including high-purity Quartz (for corrosion resistance and visibility), SS316L (for standard high-pressure applications), Hastelloy, and Inconel (for extreme high-temperature and highly corrosive conditions).

● Process Integration: Dual-Reactor Evaluation Unit is highly versatile and pairs seamlessly with various catalytic processes, including selective catalytic reduction (SCR), Fischer-Tropsch synthesis, methanol-to-olefins (MTO), VOC oxidation, and biomass gasification. It also integrates flawlessly with online analytical instruments like GC, FTIR, or MS.

Technical Specifications

Selection Guide

● Define Your Process: Clearly identify the reaction type (e.g., highly exothermic, high-pressure hydrogenation) to determine the required temperature, pressure, and reactor material.

● Parallel vs. Series: Choose parallel operation for comparing different catalysts under identical conditions. Choose series connection if you need to simulate multi-stage industrial reactors or study intermediate products.

● Analytical Needs: Determine the number of sampling points. Dual reactors require at least a 2-port or multi-port sampling valve, or dual GCs for simultaneous online analysis.

● Scale-Up Consideration: If future scale-up is planned, select a reactor diameter and catalyst bed volume that aligns with your pilot-plant dimensions to ensure kinetic data transferability.

Frequently Asked Questions (FAQ)

Q1: How does the Dual-Reactor Evaluation Unit handle the synchronization of product analysis for two parallel reactors?

A: Unlike standard units, our system features an intelligent multi-port switching valve matrix. This allows the Industrial PLC to automatically alternate the effluent from Reactor A and Reactor B into a single online analyzer (e.g., GC or FTIR) at precise intervals. This ensures that both reactors share the same high-precision analytical instrument without cross-contamination, significantly reducing equipment costs while maintaining strict data comparability.

Q2: Can the two reactors operate under completely different pressure regimes simultaneously?

A: Yes. While many dual systems share a common gas manifold, our Dual-Reactor Evaluation Unit features fully independent back-pressure regulator (BPR) loops for each reactor. This allows Reactor A to operate at atmospheric pressure for thermal cracking evaluation, while Reactor B operates at 10 MPa for high-pressure hydrogenation testing, all within the same footprint.

Q3: How does the system prevent cross-contamination when using a shared heating furnace for both reactors?

A: The dual reactors are housed in a single furnace but are physically isolated by high-performance thermal insulation baffles. Furthermore, each reactor is equipped with its own dedicated thermocouple array connected to independent PID control loops. This ensures that even if one reactor undergoes a strong exothermic reaction, the temperature of the adjacent reactor remains completely unaffected.

Q4: Does the unit support differential testing where one reactor acts as a baseline?

A: Absolutely. The PC software features a "Master-Slave" baseline tracking mode. You can set Reactor A to run a standard reference catalyst under fixed conditions, while Reactor B tests a novel catalyst with varying parameters. The software automatically overlays the conversion and selectivity curves of Reactor B against the real-time baseline of Reactor A, instantly highlighting performance deviations.
