    • The present invention relates to a process for the catalytic selective hydrogenation of a polyunsaturated organic compound, wherein the hydrogenation is carried out in a plurality of two or more series-connected loops, wherein each loop involves the use of one reactor, which comprises: (a) feeding the polyunsaturated organic compound and hydrogen to an upper part of a reactor to catalytically hydrogenate said the polyunsaturated organic compound to produce a hydrogenation product, (b) recycling a portion of said hydrogenation product back into said upper part of said reactor, (c) feeding the remainder of said hydrogenation product from said reactor to an upper part of a subsequent reactor wherein the polyunsaturated organic compound is catalytically hydrogenated to produce a subsequent hydrogenation product, and wherein a portion of said subsequent hydrogenation product has been recycled and is fed with said remainder of said hydrogenation product to said upper part of said subsequent reactor, (d) repeating step (c) until the subsequent reactor is the last reactor, (e) recovering the remainder of said subsequent hydrogenation product from said last reactor, and (f) obtaining the desired compound(s) from the product of step (e).
    • 本发明涉及多不饱和有机化合物的催化选择性氢化方法,其中氢化在多个两个或多个串联连接的环中进行,其中每个环包括使用一个反应器,其包括:( a)将多不饱和有机化合物和氢气供给到反应器的上部以催化氢化所述多不饱和有机化合物以产生氢化产物,(b)将一部分所述氢化产物再循环回所述反应器的上部( c)将剩余的所述氢化产物从所述反应器进料到后续反应器的上部,其中所述多不饱和有机化合物被催化氢化以产生随后的氢化产物,并且其中所述后续氢化产物的一部分已经被再循环并进料 所述剩余的所述氢化产物存在于所述后续的所述上部 反应器,(d)重复步骤(c),直到后续反应器为最后一个反应器,(e)从所述最后一个反应器中回收剩余的所述后续氢化产物,和(f)从下列反应产物中获得所需化合物: 步骤(e)。
