PRE-METHANATION PURIFICATION STUDY:REMOVAL OF LOW CONCENTRATION GASEOUS SULFUR COMPOUNDS (CATALYST POISONS)

摘要

The development of a viable large scale methanation process could make an important contribution to our future energy needs. However, before catalytic methanation can be used for the commercial production of synthetic natural gas from synthesis gas, the problem of methanation catalyst deactivation must be solved. During this program, a review and analysis was made of state of the art gaseous sulfur compound removal processes. Processes for the removal of both bulk and trace sulfur compounds were analyzed.
