Apr 1, 2016 · They observed significant reduction in glycerol conversion (from 95% to 47% for Amberlyst-15 and from 90% to 50% using H-beta zeolite) while switching the feed from pure glycerol to the impurities-added glycerol. A similar result has also been observed by Nanda et al. in a continuous-flow reactor (Fig. 5) [58].
Jan 15, 2024 · The yield, selectivity and conversion of PC depend on different parameters such as concentration of catalyst, reaction time, pressure of CO 2 and temperature of operation. The catalysts are mainly formed by combination of Lewis acid/Lewis base, hydrogen bond donor/hydrogen bond acceptor.

Jun 7, 2016 · ABSTRACT The renewability of bio-glycerol has made it an attractive platform for the production of diverse compounds. Selective hydrogenolysis of glycerol to propylene glycol (PG) is one of the most promising routes for glycerol valorization, since this compound is an important chemical intermediate in a number of applications. In this article, advancements in the catalytic conversion of ...
Jan 15, 2024 · However, utilization of CO 2 into useful products is still challenging because of its high thermodynamic stability (Δ f G 298K = −396 KJ/mol) [10].Thermodynamic stability of CO 2 can be countered in presence of co reactant with higher Gibbs free energy such as hydrogen, amines and epoxides [11], [12], [13] and by providing high energy in form of heat, electricity [14].
Sep 26, 2013 · The increased worldwide demand for energy, particularly from petroleum-derived fuels has led to the search for a long-term solution of a reliable source of clean energy. Lignocellulosic biomasses appear to hold the key for a continuous supply of renewable fuels without compromising with the increasing energy needs. However, the major possible solutions to the current energy crisis include ...
Oct 24, 2022 · A small fragment from Amarāvatī preserved in the Madras Government Museum illustrates the conversion of Nanda. In this scene two monks are visible. Behind him is Vajrapāṇi and to the right a woman is seated on a couch. The monks are Buddha and Nanda and the lady is Sundarī [2]. The inner face of a railing pillar from Amarāvatī preserved ...
