“…The synthesis of commodity chemicals from biomass, the only renewable source of carbon, has attracted significant research efforts in recent years owing to the increasing recognition that extensive use of fossil carbon feedstocks drives anthropogenic climate change. − Moreover, the expanding use of shale gas has made obtaining key olefin feedstocks such as propylene and butadiene more difficult, as these products are difficult to synthesize from the C 1 and C 2 hydrocarbons that constitute the majority of natural gas. , Acrylic acid (AA) and derivatives are major polymer precursors with a broad range of commercial applications, e.g., absorbents, paints, coatings, and adhesives, and they are currently produced almost exclusively via the selective oxidation of petroleum-derived propylene. , The market for AA-based materials is growing at a respectable rate while feedstock costs rise, providing an opportunity for the development of an alternative, sustainable route to produce these commodity chemicals . The dehydration of renewably sourced, cellulose-derived lactic acid (LA), and its alkyl ester derivatives, has been proposed as a viable process. , …”

The Effect of Cofed Species on the Kinetics of Catalytic Methyl Lactate Dehydration on NaY

The catalytic dehydration of biomass-derived methyl lactate to acrylic acid is a renewable route to a high-value, high-volume monomer, but achieving high selectivity and production rates remains challenging. One roadblock is that the role of the species cofed with methyl lactate, typically water, in the dehydration mechanism over alkali-metal-exchanged zeolites remains unclear. In this study, we determined the effects of protic and aprotic cofed species, including water, methanol, and methyl acetate, on the rate and selectivity of methyl lactate dehydration over NaY via kinetic and spectroscopic investigations. We show that water plays multiple competing roles in the mechanism: (1) generating the unselective Brønsted acid sites on NaY leading to acetaldehyde and coke formation; (2) suppressing the activity of the Lewis acid sites responsible for lactate dehydration; and (3) facilitating the displacement of adsorbed sodium acrylate by lactate, leading to the formation of acrylic acid. The first process increases the rate of side product formation, while the second and third processes decrease and increase the dehydration rate, respectively. As a result of these competing roles, the rate-limiting step of methyl lactate dehydration shifts from acrylate product recovery to sodium lactate dehydration as the concentration of water increases.

“…5,6 The ODHP has attracted much interest due to its exothermic nature of reaction which not requires any additional energy. 7,8 The ODHP still does not have a commercial process. Besides catalyst improvement, different reactor configurations have also investigated to improve propylene yield.…”

“…At these conditions, coke deposition and catalyst deactivation can occur which leads to increasing capital and operating costs. − There are different alternative methods to overcome the difficulties of the conventional methods. It seems that oxidative dehydrogenation of propane (ODHP) is a promising approach. , The ODHP has attracted much interest due to its exothermic nature of reaction which not requires any additional energy. , …”

The modeling of oxidative dehydrogenation of propane over the VO x /γ-Al2O3 catalyst in a bubbling fluidized bed was studied. The performance of the fluidized bed reactor was studied by using three different fluidization models with different hydrodynamic assumptions: simple two-phase (STP) model, dynamic two-phase (DTP) model, and El-Halwagi and El-Rifai [simplified Halwagi (SH)] model. The models were validated using previously published experimental data. The effects of temperature, gas velocity, propane and oxygen concentration and bed height on propane conversion, product selectivity, and propylene yield were investigated and discussed. The obtained results indicated that the SH model under-predicted the propane conversion. The STP model with simplified hydrodynamic assumptions was only suitable when reaction temperature was low. The DTP model considering dynamically distribution of gas and solid could predict propane conversion and propylene selectivity with average relative errors of 16 and 2.5%, respectively, over a wide range of experimental data, which were more accurate than those of the STP and SH models.

“…Acrylic acid (AA) is an essential chemical with broad applications in polymers and plastics [2][3][4]. Currently, acrylic acid is produced mainly from petroleum-derived products [5][6][7]. However, the objective of minimizing the environmental impact throughout products' lifecycles is motivating the production of chemicals, including acrylic acid from renewable sources, such as biomass or biomass-derived building blocks [3,8].Recently, various methods of acrylic acid production from biomass-derived products have been developed.…”

Production of energy and chemicals from biomass resources has been regarded as one promising method to address the challenge of global warming. In this research, production of acrylic acid from fumaric acid, one of the biomass-derived building blocks, is proposed. CuO was employed as a solid oxidant, which showed excellent activity and selectivity for the production of acrylic acid, and water played an essential role in acting as not only a solvent but also a catalyst in this process. An optimum acrylic acid yield of 76.4% was successfully obtained after the reaction of fumaric acid with CuO at 300 °C for only 60 s.This research provides a green and highly efficient way to produce value-added chemicals from biomass-derived building blocks, and thus is promising for practical application.
