Medium Pressure Flow Controller（MP-3050FC）

Product catalog summary
Overview: The document introduces a new flow control system designed for online gas chromatography (GC) analysis of products formed by catalytic reactions under medium pressure (up to 1 MPa). This system is particularly beneficial for reactions such as the conversion of ethanol to ethylene.
Key Features:
  • The system ensures that peak retention times on chromatograms remain unaffected by pressure changes, thanks to the use of a deactivated restrictor tube and an Open Split interface.
  • Existing GC equipment, including separation columns and detectors, can be used without modifications, facilitating easy upgrades from Tandem and Single µ-Reactors.
  • The Medium Pressure Flow Controller (MP-3050FC) is a major component, supporting various gases like helium, hydrogen, and nitrogen, and operates with a power supply of 100/240 VAC, 50W.
Specifications:
  • Reactor pressure control ranges from 0.3 to 0.98 MPa, with constant pressure control using the GC's column head pressure controller.
  • The system includes standard accessories such as a deactivated restrictor tube and an Open Split interface.
  • It is compatible with recommended GC and GC/MS systems for µ-Reactors.
User Preparation: Users need to prepare a column nut for the GC injector and a ferrule with an internal diameter of 0.5 mm. Note that Auto-Shot Sampler and Selective Sampler are not compatible with the MP-3050FC.
Application Example: The document provides an example of the system's application in the conversion of ethanol to ethylene using a catalyst (H-ZSM-5) at 250ºC with helium as the carrier gas. The split ratio is 1/100, and the sample size is 1 µL, detected using an FID detector.
Conclusion: This new flow control system offers significant advantages in maintaining consistent retention times across varying pressures, enhancing the efficiency and accuracy of GC analysis in medium pressure catalytic reactions.

Medium Pressure Flow Controller（MP-3050FC）-1

Optional accessory for Tandem and Single µ-Reactors Medium Pressure Flow controller; MP-3050FC Online analysis of medium pressure catalytic reaction MAJOR FEATURES 1) New flow control system allows online GC analysis of products formed by catalytic reaction under 1 MPa. 2) Peak retention times on chromatogram are unaffected by pressure (see figure on right). (Conversion from ethanol to ethylene) Retention times greatly altered by pressure Conventional Ethylene Employing deactivated restrictor tube and Open Split interface, retention times of peaks are independent of pressure. 3) Currently used GC, separation column, and detector can be used without modifications. 4) Easily upgradable Single µ-Reactors. Retention times unaffected by pressure and Catalyst: H-ZSM-5 at 250ºC, carrier gas: He (100 mL/min) Split ratio: 1/100, sample: ethanol (1 µL), detector: FID Column: UA1-30M-2.0F, GC oven: 30 (4 min)-@20/min-230ºC Pneumatics of MP Tandem µ-Reactor system Gas chromatograph Carrier (reaction) gas HP solid sampler Flow controller (EPC, AFC, etc.) Medium pressure flow controller MP-3050FC Flow controller Specifications • Reactor pressure control: 0.3~0.98 MPa (Constant pressure control using GC’s column head pressure controller) • Column head pressure display: digital • Supported gases: Helium, hydrogen, nitrogen, etc. • Supported GC, GC/MS: System as recommended for µ-Reactors • Standard accessories: Deactivated restrictor tube, Open Split interface, etc. • Power: 100 / 240 VAC, 50W B1 2nd µ-Reactor Split vent Medium pressure flow controller MP-3050FC User preparation • Column nut for your GC injector, ferrule (id. 0.5 mm) * Auto-Shot Sampler and Selective Sampler are not compatible with Medium-Pressure Flow Controller MP-3050FC.
