There is provided an absorbent for decreasing the leakage of halogen compound gases in subsequent processes, at high temperature and in the presence of high concentration water vapor in the process of heating and gasifying a fuel such as coal to produce synthesis gas. The present invention relates to a halogen compound absorbent containing 30 to 90% by mass of a basic calcium compound and 10 to 70% by mass of a compound of a metal other than calcium and/or of a clay mineral, and a method for producing synthesis gas using the absorbent. |
