Does liquid fuel burns with solid oxidizers ?
I bought a Bitumen paint that is around
70% Naptha, (Hydrocarbons ranging from 5-12 carbon atoms, so c5h12 to c12h26)
and around 30% Bitumen
So, the bitumen and my solid oxidizer(KNO3) can bind and solidify to become a solid propellant, but since there are so many naptha, which is a liquid
but solidified due to bonds of bitumen and KNO3, will it burn with the KNO3 ?

Some older composite propellants contained bitumen and perchlorate so yes, it will burn but may be difficult to ignite . . .

but they had no naphtha

No I don´t think it will burn, and for sure not with KNO3 as an oxidizer. I doubt even KClO3 would work due to the high naphta content, but try it
out instead of making a new, pointless thread

If the mix solidifies on standing it will burn ─ applying enough localised heat might be hit-and-miss, though!

Long-long ago I have made a rocket fuel what contained solid KClO3 and a longer chain alcohol, BuOH, ect. It was perfect til it didn't contained any
air bubble in it.
KNO3 is a weak oxidizer for this, and needs a really high temperature to burn with the naphta, but with chlorates, perchlorates it could work. The
most important thing is that never ever try it in big, max 1g.
I have a blog where I post my pictures from my work: http://labphoto.tumblr.com/
