ABSTRACT This work discusses a number ofaspects related to glycerin-relatedproduction, market, and applicationin commercial products. Three mainqualities of commercial glycerin areevaluated: raw glycerin (80-88 wt %),technical grade glycerin (98 wt %),and refined glycerin (USP or FCC,99.7 wt %). Purification schemes foreach glycerin quality are simulated.This study shows that, after purificationprocess, it is possible to obtainmethanol at 99 wt %, which canbe recycled for biodiesel production.Simulation results show that the purifyingglycerin to obtain different levelsof purity can be economically feasible,and that market quality specificationscan be reached as well.

    ABSTRACT: Acrolein was obtained by reacting gas-phase glycerol/water mixtures with zeolite catalysts. Glycerol was converted through a series of reactions involving dehydration, cracking, and hydrogen transfer and catalyzed by the acid sites of the zeolite. Acrolein was the major product; short olefins, aromatics, acetaldehyde, hydroxyacetone, acids, and acetone also were formed through a complex reaction network.

    ABSTRACT: In order to meet the very high purity requirements laid down on the European Standard for biodiesel fuel (EN 14214), a significant amount of post transesterification purification is needed. Until recently the preferred method was water washing but considerable interest is now being shown in purification by ion exchange resins and the use of magnesium silicate as a solid adsorbent. The three methods have been tested under several reaction conditions (temperature, concentration, agitation rate, etc.) in order to compare which gives better results. It has been found that it is necessary a previous methanol removal to avoid the saturation of the adsorbents. Glycerol and soap content have been removed in all the processes. Not many differences have been found on the other tested parameters.

    ABSTRACT: Petroleum is the main energy source utilized in the world, but its availability is limited and the search for new renewable energy sources is of major interest. Biofuels, such as ethanol and biodiesel, are among the most promising sources for the substitution of fossil fuels. Biodiesel can replace petroleum diesel, as it is produced from animal fats and vegetable oils, which generate about 10% (w/w) glycerol as the main by-product. The excess glycerol generated may become an environmental problem, since it cannot be disposed of in the environment. One of the possible applications is its use as carbon and energy source for microbial growth in industrial microbiology. Glycerol bioconversion in valuable chemicals, such as 1,3-propanediol, dihydroxyacetone, ethanol, succinate etc. is discussed in this review article.
