As per the statement of one of my friend, he can drop kerosene to diesel and treat the entire quantity in a big HDS (diesel hydro-treater) and make Euro IV / V Diesel.

Is it possible? What about the quality of Diesel in this case? Will HDS make things alright ?

Here the Kerosene availability is so high and they make Jet A1 and if the demand for it is not there, they want to make Diesel out of it?

Can anyone help teach me this aspect
