Embodiment approach

[0168] According to one embodiment, a proportional-integral-derivative (PID) controller controls the potential based on a feedback reading from the process value of the product gas outlet temperature of the structured catalyst.

[0169] The method described herein allows for rapid switching between conditions A and B. Suitably, therefore, switching between reaction conditions A and B occurs within a period of less than 3 hours, such as less than 2 hours, such as less than 60 min, preferably less than 30 min, even more preferably less than 15 min.

[0170] In one embodiment, switching between reaction conditions A and B includes providing a second electrical power to the structured catalyst. This suitably takes place while keeping the total flow substantially constant.

[0171] In one aspect, switching between reaction conditions A and B comprises a transition state between said reaction conditions A and B; said transition state comprises a first period of time, wherein power ...

Abstract

A reactor system and method are provided for subjecting a feedstock comprising methanol to methanol cracking and reverse water-gas shift reactions to produce syngas wherein heat for endothermic methanol cracking and reverse water-gas shift reactions is provided by resistance heating.

Description

technical field [0001] Provided is a reactor system and method for generating synthesis gas from a feedstock comprising methanol in the presence of a catalyst under methanol cracking and reverse water gas shift reaction conditions, wherein heating is provided for methanol cracking and reverse water gas shift reaction of heat. Background technique [0002] Syngas production typically takes place in large chemical plants due to the energy-intensive reactions required to facilitate production. This makes small-scale production difficult. Furthermore, the toxicity of syngas (especially due to the carbon monoxide content) makes its storage difficult and entails significant risks. [0003] There is a need for on-demand production of syngas using relatively simple production setups in smaller facilities requiring minimal operator input to produce syngas using readily storable reactants. [0004] Systems and methods for performing endothermic catalytic reactions are described in ...
