    • Methods for dehydrogenating one or more alkanes. A catalyst can be contacted with an alkane under a pressure of less than 101 kPa to produce a coked catalyst and a dehydrogenated product. The dehydrogenated product can be separated from the coked catalyst and the coked catalyst can be contacted with a purge fluid to remove at least a portion of any residual alkane, any residual alkene, or a combination thereof from the coked catalyst. The coked catalyst can be contacted with an oxygen-containing fluid and at least a portion of the coke disposed on the catalyst can be combusted in the presence of the oxygen-containing fluid to produce a decoked catalyst. The decoked catalyst can be contacted with a reducing gas to produce a regenerated catalyst and an off-gas. Additional alkane can be contacted with the regenerated catalyst to produce additional dehydrogenated product and additional coked catalyst.
    • 一种或多种烷烃脱氢的方法。 催化剂可以在低于101kPa的压力下与烷烃接触以产生焦化催化剂和脱氢产物。 脱氢产物可以与焦化催化剂分离,并且焦化的催化剂可与吹扫流体接触,以从焦炭催化剂中除去残余的烷烃,任何残余的烯烃或其组合的至少一部分。 焦化的催化剂可以与含氧流体接触,并且设置在催化剂上的焦炭的至少一部分可以在含氧流体的存在下燃烧,从而产生一个开馏的催化剂。 可以将经脱色的催化剂与还原气体接触以产生再生催化剂和废气。 另外的烷烃可与再生催化剂接触以产生额外的脱氢产物和另外的焦化催化剂。

    • Processes and systems for recovering products from a corn fermentation mash. In one example, a process for recovering products from a corn fermentation mash can include separating ethanol from a fermentation mash to produce a whole stillage. The fermentation mash can be derived from a ground corn product milled from a plurality of corn pieces. The plurality of corn pieces can include whole corn kernels, fragmented corn kernels, size- reduced corn kernels, milled corn kernels, or a mixture thereof. Greater than 25 wt% of the ground corn product can have a particle size of greater than 105 μιη and greater than 80 wt% of the ground corn product can have a particle size of 425 μιη or less, as measured according to AOAC 965.22-1966. The process can also include separating the whole stillage to produce a fiber rich portion and a filtrate.
    • 用于从玉米发酵ma中回收产品的过程和系统

      在一个实例中,从玉米发酵ma中回收产物的方法可以包括从发酵ma中分离乙醇以产生完全酒糟。 发酵ma可以来源于从多个玉米片碾磨的磨碎的玉米产品。 多个玉米片可以包括全玉米粒,碎片玉米粒,大小减小的玉米粒,碾磨玉米粒或其混合物。 磨碎的玉米产品的大于25重量%可以具有大于105μm的粒度,并且根据AOAC 965.22-1966测量,磨碎的玉米产品的大于80重量%的粒度可以具有425μm或更小的粒度 。 该工艺还可以包括分离整个釜馏物以产生富含纤维的部分和滤液。
