Is it possible to improve the reforming section of the Haber-Bosch process without using air separation units?

A typical reforming section in a large-scale Haber-Bosch process (Figure 1) comprises two reactors. A mixture of methane (CH4) and steam (H2O) is fed into a primary reformer to produce syngas via...

Is there any real advantage in co-electrolyzing CO2 and H2O in liquid phase to produce syngas versus using separated electrolysis of H2O and CO2?

Electrochemistry is a pathway to convert CO2 into valuable products such as CO. However, a potential side product in the cathode is H2. I wonder if it is possible to tune the composition of the...

Can pulsed electric fields be used to generate heat?

Pulsed electric field is considered a "non-thermal" method for food processing that involves the application of short high-voltage pulses to create pores in cell membranes. However, since I am not...

Can microampere discharges produce changes in chemical reactions?

We are applying 600VDC to a dielectric barrier discharge (DBD) reactor with a nickel electrode and CO2 and H2 as reactants to produce CO and H2O. Argon is added as internal standard. The reactor...

Can current leak through fused quartz at high temperatures?

We are applying high voltage (~600 VDC) at 700 degrees C to a system where fused quartz is being used as an electric insulator. However, our instruments are detecting a current of ~100 uA and we...

To what extent the presence of methane impurities can affect the performance of a catalyst that converts syngas to dimethyl ether?

The simplest way to convert syngas to DME in one step is by combining a catalytst for methanol synthesis (say, Cu-Zn/Al2O3) and an acidic one for methanol dehydration (perhaps zeolites). However,...

Is there any catalyst that can efficiently produce syngas out of methane at temperatures of 300C and lower?

Methane reforming is usually carried out using steam as oxidizing agent but at temperatures of 500 degrees C and higher. I was wondering if there is any other reforming technology to produce...
