What are the advantages of magnesium oxide in catalysts

With the continuous construction of ecological civilization and the increasing reduction of fossil resources,finding a clean and environmentally friendly renewable alternative energy source has become an important issue that people are facing.

1、Environmental analysis
With the continuous construction of ecological civilization and the increasing reduction of fossil resources,finding a clean and environmentally friendly renewable alternative energy source has become an important issue that people are facing.Catalytic biodiesel is a green and environmentally friendly renewable liquid fuel.However,the homogeneous acid-base catalysts currently used in industry,such as HCl,H2SO4,KOH,NaOH,CH3ONa,CH3OK,etc.,are prone to corrosion,difficult to recover catalysts,difficult to refine,difficult to separate and purify by-products of glycerol,and generate too much waste liquid,which reduces the utilization rate of raw materials and increases industrial production costs.In order to overcome the problems of homogeneous acid-base catalysts,magnesium oxide alkaline catalysts have received widespread attention.

2、The benefits of using magnesium oxide as a catalyst
Magnesium oxide solid base catalyst is an efficient and stable heterogeneous solid catalyst with high catalytic activity for ester exchange reactions,easy separation,reusability,low cost,and abundant supply.It is a type of solid base catalyst with very good application prospects.In addition,the reaction products esters and by-products glycerol are neutral and do not require washing,effectively avoiding the generation of waste liquid and not causing harm to the ecological environment.
3、The benefits of using magnesium oxide as a catalyst carrier
Magnesium oxide can not only be used as a catalyst,but also as an important catalyst carrier.For example,Ni/MgO catalysts using magnesium oxide as a carrier can catalyze the reaction of carbon dioxide and methane,converting the two greenhouse gases into a mixture of hydrogen and carbon monoxide,which can be used as fuel to achieve comprehensive utilization.
In the process of removing hydrogen halides from halobutane by magnesium oxide,polymers can remove small molecules of hydrogen halides under the catalytic action of magnesium oxide.At the same time,hydrogen halides are adsorbed on the surface of magnesium oxide and react with it to produce water and magnesium halides.Among them,magnesium halide can be transformed back into magnesium oxide after calcination under certain conditions.This catalytic effect is very significant in treating white pollution and degrading polymers.
4、Summary
In fact,magnesium oxide plays an important role both as a catalyst and as a catalyst carrier,and is widely used in various industries.
