on a number of noble metal, non-noble metal and bimetallic catalysts on various
supports, along with the activity, selectivity and yield data, have been covered in the
review. Different types of catalysts for the production of sugar alcohols by hydrogenation and hydrogenolysis of mono- and disaccharides have been described in
another review by Ruppert et al. [92]. Erythritol, a C 4 sugar alcohol, is obtained
from pentose sugars (xylose and arabinose) by selective cleavage of C-C bond.
Several homogeneous and heterogeneous catalysts have been explored [136] for
this process which requires mild reaction conditions (<180 °C temperature and
<60 bar hydrogen pressure) to minimize side reactions and achieve selective C-C
bond cleavage to yield erythritol [137, 138]. Several microbial processes for the
production of sugar alcohols have been described in a review by Kunz et al. [56].
