Life-cycle Analysis of Bioproducts and Their Conventional Counterparts in GREET

“…They investigated the life-cycle impacts of producing four compounds (N-methylpyrrolidone, N-vinylpyrrolidone, acrylonitrile, and succinonitrile) sourced from sugar beet vinasse-derived glutamic acid, an amino acid from a low-value byproduct. To complete the material and energy flows in the supply chain of NMP, we used material and energy consumption data for the production of GBL and methylamine from Javaid and Bildea (2014) and Righi et al (2011) respectively. Javaid and Bildea (2014) reported the heat requirement to drive the vapor phase endothermic catalytic dehydrogenation of 1,4-butanediol (BDO) to GBL (0.7 MMbtu/ton).…”

Theoretical Insights into the Reaction Mechanism of Direct Hydrogenation of Maleic Anhydride to Produce 1,4-Butanediol on the Cu–ZnO Surface

“…In previous studies on Cu-based catalysts, the focus has been more on coupling maleic anhydride hydrogenation with 1,4-butanediol dehydrogenation to produce γ-butyrolactone. 22 Therefore, maleic anhydride and 1,4-butanediol, as reactants, need to be stably adsorbed on the catalyst surface for activation. Succinic anhydride, γ-butyrolactone, and tetrahydrofuran, as well as CO 2 and H 2 O as products at different hydrogenation degrees, exhibit relatively weak adsorption on the catalyst surface, making them prone to desorption and separation.…”

“…Consequently, previous research predominantly focused on the direct hydrogenation of maleic anhydride to produce γ-butyrolactone by using Cu-based catalysts. There was also considerable research on coupling the hydrogenation of maleic anhydride with the dehydrogenation of 1,4-butanediol to produce γ-butyrolactone. , With the rapid development in the field of biodegradable plastics in recent years, the demand for 1,4-butanediol has steadily increased. Improving the route of direct hydrogenation of maleic anhydride to generate more 1,4-butanediol has become a critical concern.…”

Coupling exothermic and endothermic reactions—Application to combined aniline production/methyl‐cyclohexane dehydrogenation

“…The interaction between the adiabatic reactor and the separation section, due to material recycle, may be the source of undesired nonlinear phenomena (such as instability and parametric sensitivity, which leads to controllability problems. Behavior of integrated systems is analyzed in few studies and found this new process intensification technique feasible and beneficial. This article presents the design of an integrated plant for the combined production of TOL and AN.…”
