ADSORBENT FOR REMOVING ACID GAS IN HYDROCARBONS OR HYDROGEN, AND ITS PREPARATION METHOD

摘要

PURPOSE: Absorbent for removing acid gas from hydrocarbons or hydrogen and a manufacturing method of the same are provided to improve stability and absorption by being made of materials with high reactivity to acid gas. CONSTITUTION: Absorbent for removing acid gas includes a core part and an outer shell part. The core part includes a first absorbent component and a first adjusting component. The outer shell part includes a second absorbent component and a second adjusting component. The content of the first absorbent component is higher than the content of the second absorbent component. The content of the second adjusting component is higher than the content of the second adjusting component. The absorbent components are selected from a group including calcium hydroxide, zinc oxide, calcium oxide, sodium carbonate, or the mixture of the same. The adjusting components are selected from a group including diatomite, bentonite, sodium aluminate, aluminum oxide, silicon dioxide, and the mixture of the same.
