In an example, a method of butadiene sequestration includes receiving an input stream that includes butadiene. The method includes directing the input stream to a first sulfur dioxide charged zeolite bed for butadiene sequestration via a first chemical reaction of butadiene and sulfur dioxide to form sulfolene.
