PURPOSE : A desulfurization adsorbent having excellent desulfurization performance and regeneration characteristics, a desulfurization method for removing sulfur compounds in fuel using the desulfurization adsorbent, a regeneration method for regenerating the desulfurization adsorbent having sulfur compounds adsorbed thereon, a desulfurization equipment comprising the desulfurization adsorbent, and a fuel cell system comprising the desulfurization adsorbent are provided. CONSTITUTION : A desulfurization adsorbent is a porous crystalline molecular sieve and has structure of the chemical formula, (M1)a-(Si)x-(Ti)y-(M2)z-O, where M1 is one or more selected from an alkali metal, an alkali earth metal, hydrogen, ammonium, and rare earth metal or a transition metal, 4<=x/y<=500, 0<=z/y<=3, 0
