Why we add acetic acid in CaCl2 during Cobalt Nitrate Complex Preparation?
Answers
The effects of pretreatment with acetic acid on dried cobalt nitrate catalysts were examined.
In liquid-phase Fischer–Tropsch synthesis, a cobalt catalyst made from cobalt nitrate and treated with 2.2 M acetic acid, dubbed CoN/2.2Ac, demonstrated the best CO conversion and the lowest CO2 and CH4 selectivities.
The catalytic activity of a cobalt catalyst made from cobalt acetate, on the other hand, was weak due to the low reduction degree of supported cobalt.
During acetic acid treatment, the enhanced catalytic activity of the CoN/2.2Ac catalyst could be attributed to the creation of a mixture of cobalt nitrate and cobalt acetate with an appropriate ratio between them.
This method in which acetic acid is added in CaCl₂ during cobalt nitrate preparation is known as Fischer's Tropsch
Explanation:
During the Cobalt Nitrate Complex Preparation acetic acid is added to CaCl₂.
In Fischer Tropsh method
A cobalt catalyst made from Cobalt nitrate is treated with acetic acid
Cobalt nitrate and acetic acid helps in the conversion of CO, CO₂ and CH₄
the catalyst is helpful in the low reduction of cobalt
They have an enhanced catalyst activity.
