Catalytic Oxidation of CO and VOC in Flue Gas of Coffee Roasting Machines
Chemie Ingenieur Technik, EarlyView.Platinum‐coated cordierite monoliths effectively oxidized CO and VOC in coffee roasting exhaust with higher Pt loadings lowering light‐off temperatures. Scaled up 90 g/ft3 catalyst in a 5 kg roaster achieved 96% CO and around 78% VOC conversion at 350°C, highlighting stable operation requires flue gas temperatures ≥350°C.

Selective Non‐Catalytic Reduction of NOx in the Exhaust Gas of Small Wood Gasification Boilers
Chemie Ingenieur Technik, EarlyView.Kinetic studies of the SNCR reaction were conducted to investigate NOx reduction in the exhaust gas of small‐scale wood gasification boilers. Both the experimental results and the derived global kinetic model indicate that SNCR can achieve a significant reduction in NOx emissions under typical operating conditions. ABSTRACT The gas‐phase reaction of NO

Comparative Study of Gas and Liquid Flow in Packed Beds Using Phase‐Contrast MRI
Chemie Ingenieur Technik, EarlyView.This work presents applications of phase‐contrast magnetic resonance imaging (MRI) to investigate fluid flow fields and temperature in packed beds. Comparison of ethane (C2H6) gas flow with that of water flow is done at similar flow conditions. The temperature of water is also measured using MRI.

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.

Methanol With Increased Water Content in Internal Combustion Engines
Chemie Ingenieur Technik, EarlyView.This study investigates the potential to improve overall Well‐to‐Wheel efficiency by using low‐purity methanol from synthesis of hydrogen and furnace gas as CO2‐source. Combustion efficiency is comparable to pure methanol, while distillation energy could be saved.

Chemie Ingenieur Technik, EarlyView.Combining the coating and transportation of particles into a single process step promises time savings and omits the need for separate coating equipment. Experiments were conducted using a vacuum pneumatic conveying system equipped with custom rapid‐prototyped nozzles and coating chambers.

Assessment of Gibbs Free Energy Calculation in PI‐Controlled Heating
Chemie Ingenieur Technik, EarlyView.For description and control of chemical processes in lab or industry thermodynamic variable Gibbs free energy provides opportunity to compare and interpret phenomena, even on a quantitative level. In a case study for PI‐controlled heating, impacts on its limits from control delay until parameter quantization are highlighted and assessed.
