    Nickel Sponge Process

    Apr 30, 2004 The biosorption process for the removal of nickelII by loofa sponge-immobilized biomass of Chlorella sorokiniana LIBCS, a newly developed immobilized biosorbent, was characterized. Effects of environmental factors on metal uptake capacity of LIBCS were studied and compared with free biomass of C. sorokiniana FBCS.

    Life Cycle Assessment Of Sponge Nickel Produced By Gas

    Aug 03, 2012 Aug 03, 2012 The butyraldehyde is then hydrogenated using a sponge nickel catalyst to produce butanol. Both the butyraldehyde step 1 and butanol step 2 production are typically performed within the same plant however, the primary subject of this LCA is the effect of sponge nickel activity on the efficiency of the butanol process step 2.
