Oxygen it is.
Paper content is hydrocarbon, it is carbon and hydrogen atom in the cellulose. Carbon combust with oxygen forming carbon dioxide and hydrogen combust with oxygen forming water.
Oxygen
Burning release carbon dioxide and water vapors.
Actually, some acids do burn litmus paper. Hydrochloric acid, for example, can burn paper, but the litmus on litmus paper shields the paper from the acid. Sulfuric acid, however, has dehydration properties, and would suck the water right out from the paper, charring it instantly.
if you burn natural gas in a boiler it is useful or harmful
There is no element that can hold ancient paper as a gas in a bottle. Paper is a solid material, not a gas, and it cannot be transformed into a gas by any means.
Oxygen.

Oxygen is needed to feed the flame.
Depending on the fuel, Oxygen is the main gas.
oxygen is needed for fuel to burn

That depends on the type of reaction occurring. Things don't just burn slowly or quickly, they burn at different rates depending on the material and the condition of the material. For example, if you burn a thin, unfolded piece of paper, it will burn relatively quick. If you burn a thick, crumpled up piece of construction paper, it will burn relatively slow. Additionally, an unfolded piece of paper will burn faster than a crumpled up piece of the same paper, but they will give off the same amount of heat. Think of it like having gas in a car. If you put a gallon of gas in a Ferrari and a gallon of gas in a Toyota Prius, drive them until they run out of gas and then ask which one used more gas, the answer will be neither. They both used the same amount of gas. The Ferrari will have burnt all of its up quickly and violently and the Prius will have made it last much longer, but the amount of gas used by each car is the same.
Burning release carbon dioxide and water vapors.
It is not conserved, as you burn the piece of paper the energy is released.
yes u can burn paper towels you can use a lighter.
