Title

Analyses Of Hydrogen Production From Sub-Quality Natural Gas (I): Sqng Thermal Decomposition And Autothermal Process

Abstract

Due to the high cost of removing H2S from sub-quality natural gas (SQNG) using current processing technologies, SQNG wells are often capped and the gas remains in the ground. A two-step hydrogen production scheme using SQNG as feedstock was proposed and analyzed using. The first step of the process involves hydrocarbon processing (via SMR, partial oxidation or pyrolysis) in the presence of H2S. In the second step, after the separation of hydrogen from the main stream, un-reacted H2S is used to reform the remaining methane and generate more H2 and CS2. Thermodynamic analyses on an SQNG feedstock containing 10 vol % H2S have shown that no H2S separation is required in this process. This is an abstract of a paper presented at the 230th ACS National Meeting (Washington, DC 8/28/2005-9/1/2005).
