摘要： The present invention provides methods for manufacturing olefins such as ethylene and propylene from lower alkanes, that is, methane, ethane and/or propane, by oxidative dehydrogenation at elevated pressure. The olefins are selectively recovered from unconverted lower alkane feed and reaction byproducts by using a complexation separation, such as an absorption separation that uses aqueous silver nitrate as the complexation agent. Catalysts are used that give high selectivity for oxidative dehydrogenation of lower alkanes to olefins at elevated pressure, such as a nonstoichiometric rare earth oxycarbonate catalyst.

摘要： Sulfur resistant/tolerant adsorbents useful for separating olefins from paraffins in a cracked gas stream including hydrogen sulfide. The method comprises the steps of contacting the gaseous mixture with an adsorbent which preferentially adsorbs the alkene, at a selected temperature and pressure, thereby producing a nonadsorbed component and an alkene-rich adsorbed component; the adsorbent comprising a carrier having a surface area, the carrier having a monolayer of a silver compound or a copper compound, the silver or copper compound releasably retaining the alkene; and changing at least one of the pressure and temperature to thereby release the alkene-rich component from the adsorbent. The adsorbent substantially maintains its adsorbent capacity and preference for the alkene in the presence of the sulfur compound. Sulfur resistant/tolerant adsorbents uesful for selectively separating dienes from a mixture, particularly one containing mono-olefins and hydrogen sulfide, are also disclosed.
摘要翻译：耐硫/耐受吸附剂可用于在包括硫化氢的裂化气流中从链烷烃中分离烯烃。该方法包括以下步骤：在选择的温度和压力下使气体混合物与优先吸附烯烃的吸附剂接触，由此产生非吸附组分和富含烯烃的吸附组分; 所述吸附剂包括具有表面积的载体，所述载体具有单层银化合物或铜化合物，所述银或铜化合物可释放地保留所述烯烃; 并且改变压力和温度中的至少一个，从而从吸附剂中释放富烯烃组分。吸附剂在硫化合物的存在下基本上保持其吸附能力和对烯烃的偏好。还公开了用于从混合物中选择性分离二烯的耐硫/耐受吸附剂，特别是含有单烯烃和硫化氢的二硫化物。
