Sulfur management for processes and control systems for the efficient anaerobic conversion of hydrogen and carbon oxides to alcohols

The invention relates to sulfur management for processes and control systems for the efficient anaerobic conversion of hydrogen and carbon oxides to alcohols. Specifically, high conversion efficiencyprocesses are disclosed for the anaerobic bioconversion of syngas to alcohol by microorganisms having metabolic processes that utilize sulfur in limited amounts. The processes remove hydrogen sulfidefrom the gas leaving the bioreactor assembly by forming sulfur compounds that are beneficial to the microorganisms. The sulfur compounds can be returned to the bioreactor assembly to meet a portion ofmicroorganism sulfur demand. 本发明涉及氢气和碳氧化物有效地厌氧转化成醇的方法和控制系统的硫管理。具体而言，公开了通过微生物将合成气厌氧生物转化成醇的高转化效率方法，所述微生物具有使用有限量的硫的代谢过程。该方法通过形成对微生物有利的硫化合物而从离开生物反应器装置的气体中除去硫化氢。硫化合物可返回生物反应器装置中以满足一部分的微生物硫需求。
