How do catalytic reactors work?

Reactors with significant motion of catalyst particles A fluidized bed reactor suspends small particles of catalyst by the upward motion of the fluid to be reacted. The fluid is typically a gas with a flow rate high enough to mix the particles without carrying them out of the reactor.

What type of reactor is used in hydrogenation?

Hydrogenation is a chemical reaction between a compound and hydrogen. In the fine chemicals industry, hydrogenation is commonly performed in a fixed-bed catalytic reactor. An unsaturated hydrocarbon, such as an alkene or alkyne, is reduced in the presence of hydrogen to form a saturated (or more saturated) hydrocarbon.

Why nickel is used as a catalyst?

Nickel-based catalysts are the most frequently used in reforming reactions due to C–C bond rupture capability. Nickel has been generally supported onto alumina because of its ability to withstand reaction conditions.

How to choose the best multiproduct catalytic hydrogenation unit?

The requirements for a good multiproduct catalytic hydrogenation unit as well as the choice of the reactor type are considered. Packed bed bubble column reactors operated without hydrogen recycle are recommended as the best choice to obtain a flexible reactor with good selectivities.

How does hydrogenation work in a hydrocarbon reactor?

In the schematic shown above, unsaturated hydrocarbon is injected into a reactor via a liquid control valve and hydrogen gas is injected into the reactor using a Mass Flow Controller (MFC). A fixed bed heterogeneous catalysis reactor accelerates the hydrogenation process.

What are heterogeneous catalysts and reactors?

Reactors using heterogeneous catalysts are central to several industrial-scale processes, such as the production of hydrocarbon fuels. This video illustrates the principles of heterogeneous catalysts and catalytic reactors, demonstrates a pilot-scale catalyzed ethylene hydrogenation process, and discusses some applications.

Why do we need a catalyst in a hydrogen reactor?

It should also be noted that the evaporation of solvent or reactant re- duces the partial pressure of hydrogen, above all in the upper part of the reactor. This aspect necessitates additional catalyst.
