  2. Industrial catalysts - Wikipedia

    en.wikipedia.org/wiki/Industrial_catalysts

    The reaction is exothermic with ΔH= -41.1 kJ/mol and have an adiabatic temperature rise of 8–10 °C per percent CO converted to CO 2 and H 2. The most common catalysts used in the water-gas shift reaction are the high temperature shift (HTS) catalyst and the low temperature shift (LTS) catalyst.

  3. Water–gas shift reaction - Wikipedia

    en.wikipedia.org/wiki/Water–gas_shift_reaction

    The water–gas shift reaction (WGSR) describes the reaction of carbon monoxide and water vapor to form carbon dioxide and hydrogen: CO + H 2 O ⇌ CO 2 + H 2. The water gas shift reaction was discovered by Italian physicist Felice Fontana in 1780. It was not until much later that the industrial value of this reaction was realized.

    Using these methods, steady state temperature distribution was computed as well as the peak temperature as a function of time for a cubic die. For an input power of 0.3 W {\displaystyle 0.3W} (or 3.333 e 8 W / m 2 {\displaystyle 3.333e8W/m_{2}} ) applied over a single surface source on the top of a cubic die a peak increment of temperature in ...

  5. Thyristor power controller - Wikipedia

    en.wikipedia.org/wiki/Thyristor_power_controller

    Some operating conditions require switching in each half-wave and thus very fast operation. Examples are control sections with very fast behavior or a required current limitation with low element resistance in the cold state. In this operating mode, the controller changes the phase angle α of the thyristor ignition timing.

  6. Catalytic heater - Wikipedia

    en.wikipedia.org/wiki/Catalytic_heater

    A catalytic heater is a flameless heater which relies on catalyzed chemical reactions to break down molecules and produce calefaction (heat). [1] When the catalyst, fuel (e.g., natural gas), and oxygen combine together, they react at a low enough temperature that a flame is not produced.

    The control group in Tuesday's release, which excludes several volatile categories and factors into the gross domestic product reading for the quarter, increased by 0.4%, in line with estimates.

  8. Bang–bang control - Wikipedia

    en.wikipedia.org/wiki/Bang–bang_control

    A water heater that maintains desired temperature by turning the applied power on and off (as opposed to continuously varying electrical voltage or current) based on temperature feedback is an example application of bang–bang control. Although the applied power switches from one discrete state to another, the water temperature will remain ...
