Question

I'm using the Calcium Looping process, where I have Calcium Hydroxide that converts into Calcium Carbonate. I'm trying to loop the Carbonate back to form Calcium Hydroxide.

So far, what I can find is the most common process is Calcination -- heating up the CaCO3 with water to up to 1000 degrees C. Then adding water to the Calcium Oxide will result in Ca(OH)2.
I've read in an article that there has been an innovation in Carbonate Hydrolysis where this reaction can be performed closer to 400 degrees C but I'm unable to find the research behind this.

Answer 1

In the Calcium Looping process, Calcination is commonly used to convert calcium carbonate into calcium oxide and then adding water to produce calcium hydroxide.

However, there has been an innovation in carbonate hydrolysis that allows this reaction to be performed at a lower temperature, but specific research behind this innovation isn't available.

Step-by-step explanation:

Calcination is a widely used process to convert calcium carbonate (CaCO3) into calcium oxide (CaO) by heating it up to 1000 degrees C, and then adding water to the calcium oxide to produce calcium hydroxide (Ca(OH)2).

However, there has been an innovation in carbonate hydrolysis that allows this reaction to be performed at a lower temperature, around 400 degrees C.

Unfortunately, I couldn't find specific research behind this innovation.
