Preparation of desulfurizing absorbent from mixture of soda-manufacturing waste residue as well as calcium carbide residue, influencing of different mixing ratios on the specific surface area and desulfurizing capacity of absorbent are discussed.

Using sorbent with low sulphur,high purity oxygen for reaction and carrier gas of Ar,the overall contents of sulphur in light oil products was determined by using microcoulometry method,which can quickly determine sulphur up to 0.
