I would translate Revelation 8:3-4 this way:
3Then another angel came and stood over the altar, having a goldergolden censer. And he was given much incense that he might offer for the prayers of all the saints, upon the altar ‒ the golden altar before the throne. 4And so it rose up ‒ the smoke of the incense for the prayers of the saints, from the hand of the angel in the presence of God.
The incense is being offered by the angel FOR the prayers of the saints. The smoke of the incense rises up, not the prayers of the saints. The prayers of the saints, as represented by the smoke of the incense, is a pleasing odour to the LORD as was the smoke of the burnt offerings of an obedient Israel a "sweet savour unto the LORD" (Leviticus 1:9,13,17).
Unless one has a mental image of the Creator with an olfactory system (made of atoms as is the creature's), then the words of John are symbolic of the pleasure the LORD receives from those whose hearts are set on doing what pleases Him.
