On Metal Carbonyl Compounds in Catalytic Methanol Synthesis: Detection, Consequences, and Removal
Chemie Ingenieur Technik, EarlyView.Deactivation of Cu/ZnO/Al2O3 catalysts by metal carbonyl compounds in the feed gas is a critical problem in catalytic methanol synthesis. We utilize PTR–MS to identify potential chemical sources, detect contamination in an in‐house CO gas line, and validate filter methods for removing these catalyst poisons before synthesis.

Process Gas Transitions in the Steel Industry—Planning Corridors for Chemical Utilization
Chemie Ingenieur Technik, EarlyView.Scenario‐based planning corridors link route‐ and pace‐dependent steelworks off‐gas availability (BFG, BOFG and SAFG) to a 1000 mtpd methanol demand over 2030–2060, revealing pace‐limited BFG concepts and route/site‐size limits for CO‐rich operation and motivating early CO2 tie‐ins as retrofit‐friendly safeguards.

Techno‐Economic Analysis of Methanol Production From Steel Mill Gases
Chemie Ingenieur Technik, EarlyView.A techno‐economic analysis for the synthesis of methanol from steel mill gases is carried out. Four different process concepts are defined and analyzed. The analysis yields levelized cost of methanol estimates between €1130 and €1419 t−1. Sensitivity analyses identify hydrogen production as the largest contributor to cost.

A novel bubbling fluid bed reactor for the autothermal pyrolysis of waste plastics
The Canadian Journal of Chemical Engineering, EarlyView.Abstract A new pilot‐scale fluidized bed reactor operated under continuous conditions was developed and tested for the thermal pyrolysis of high‐density polyethylene (HDPE). The study focused on assessing the reliability and operability of the system under different operating conditions (400–550°C), while monitoring mass and energy balances, product ...
