The biotechnological production of organic compounds using renewable carbon sources is an approach consistent with sustainable development and green technologies. The development of these processes requires refinement of both the upstream stage, including the selection of microorganisms and the use of waste raw materials, and the downstream stage. The fermentation broth contains not only the main product but also unreacted substrates and by-products. The paper presents computer simulations that analyse the possibility of using esterification for the separation of lactic acid from acetic acid. The standard distillation approach does not allow for a high degree of separation, but a distillation step is possible for esters of both acids. As a result, high-purity ethyl lactate is obtained and, by introducing a hydrolysis step, pure lactic acid. The issue was analysed using Chemcad software with the UNIFAC thermodynamic model.

Systems based on physical sorption are an attractive solution for CO2 capture from flue gases, biogas upgrading or gas storage. Besides the sorbent choice, one of the most important factors related to the design of such systems is proper heat management. Commonly used sorbents typically have low thermal conductivity. Nevertheless, catalyst particles characterized by high conductivity are inherently present in adsorptive (hybrid) reactors. Thus, appropriate structuring of hybrid beds can be used for controlling temperature profiles and improving the bed performance. In this study, the behaviour of a nonadiabatic adsorptive reactor described by a two-dimensional model was analysed for the adsorption step. The effect on the CO2 adsorption performance of different spatial distributions of functionalities in the bed was investigated. The optimality problem for nonuniform radial distribution of sorbent and catalyst in the bed was solved, indicating that such a configuration is a potentially important direction for structuring hybrid beds. Results demonstrate that the optimal configuration of radially distributed functionalities significantly increases the amount of CO2 absorbed under identical boundary and initial conditions for the bed. It appears that precise control of the heat generated and removed from the bed is achievable. Such control could be advantageous for the regeneration phase.

Generating hydrogen, through alkaline water electrolysis shows promise as an energy source. This review delves into the significance of choosing the electrodes and evaluating catalysts to enhance the efficiency and performance of hydrogen production. It summarizes the activation energy and losses linked to reactions in alkaline electrolysis emphasizing the necessity for electrode materials and catalysts. The review also touches upon challenges such as electricity consumption and platinum group metal based electro catalysts proposing various electrode materials and catalysts with superior activity and selectivity for hydrogen production. Additionally, it discusses electrolysis cell designs that facilitate separating by-products from hydrogen gas. The study reveals that with low over potentials of 70, 318, and 361 mV at 10, 500, and 1000 mA cm−2, respectively, NiOx/NF exhibits strong alkaline hydrogen evolution activity, resulting in great performance in alkaline HER. Moreover, it outlines advancements in alkaline water electrolysis technology focusing on enhanced efficiency and reduced operating costs associated with electricity consumption. Overall this review underscores the role of selecting electrodes and evaluating catalysts in optimizing hydrogen production from alkaline water electrolysis.

3D printing has recently been experiencing a period of extremely rapid development. This is due to the fact that researchers as well as the industry recognize the many advantages of 3D printing. The dynamic development of this field brings about the advancement of new technologies, leading to the search for new photocurable resin formulations that enable efficient 3D printing in various environments. The development of an appropriate photocurable resin for 3D printing in the aqueous environment of electroplating baths is a crucial aspect in designing new devices for multi-material 3D printing that utilize coupled processes of electrodeposition and photopolymerization. Therefore, this article analyzes the effect of different environments on the kinetics of the photopolymerization process of photo-curable compositions dedicated to 3D printing. The study was carried out in four different environments: argon, water, saturated copper (II) sulfate solution and saturated copper (II) sulfate solution acidified with monomolar sulfuric (VI) acid. The work used techniques such as Fluorescent Probe Technique, photorheology, rheology and Raman spectroscopy to investigate the course of the photopolymerization process. The results of the experiments showed that the environment has a significant effect on the degree of conversion of monomers and on the rate of the photopolymerization process itself.

The influence of the agitator type, agitator speed, superficial gas velocity, type of sugar (glucose or sucrose) and the presence of yeast in the system on the gas hold-up in an agitated vessel with 24 vertical tubular baffles (located on the circuit in the vessel) has been presented in this paper. The measurement of gas hold-up was conducted in an agitated vessel with inner diameter of D = 0.288 m and liquid height of H = 0.288 m. Three different agitators were used in the experimental study. Five gas-liquid and two biophase-gas-liquid systems were agitated in an agitated vessel. Air was used as gas. The influence of gas flow number, Weber number, the mass fraction of aqueous sugar solution ci, and mass fraction of yeast suspension ys for gas-liquid and biophase-gas-liquid systems on the gas hold-up ϕ was described mathematically. These equations do not have equivalents in the literature.

Abstrakt

Activated carbons (ACs) produced from end-of-life tires with different tire pyrolysis char (TPC)-to-activator (KOH) ratios of 1:2, 1:3, and 1:4 were prepared and characterized. These materials were used as adsorbents for the removal of two common chloroorganic water contaminants such as 2,4-dichlorophenol (DCP) and 2,4-dichlorophenoxyacetic acid (2,4-D). The adsorption kinetics, equilibrium adsorption, and effects of solution pH were investigated. The adsorption of both adsorbates was found to be pH-dependent and preferred in acidic environments. The adsorption kinetics was evaluated using pseudo-first-order and pseudo-second-order kinetic models and mechanism - using Weber-Morris and Boyd models. Results demonstrated that the adsorption of DCP and 2,4-D on all ACs followed the pseudo-second-order model and was controlled by film diffusion. The Langmuir isotherm described the equilibrium data better than the Freundlich isotherm model. The maximum adsorption capacity of DCP adsorbed on AC1:2, AC1:3, and AC1:4 at equilibrium was 0.582, 0.609, and 0.739 mmol/g, respectively, while the maximum adsorption capacities for 2,4-D were 0.733, 0.937, and 1.035 mmol/g, respectively. The adsorption rate and efficiency were closely correlated with the porous structure of the tested adsorbents. The results showed that the activated carbons obtained from the scrap of end-of-life tires as raw materials could be used as a low-cost and alternative adsorbent for the removal of chlorinated organic pollutants from water.

Abstrakt

3D printing has significantly evolved in recent years. Initially, only plastics were used as materials for 3D printing, but technological advancement has enabled 3D printing with materials such as metals, ceramics and biomaterials. With the development of 3D printing, there emerged a need to create a printer for producing hybrid parts, such as metal-plastic, characterized by both the exceptional strength and durability of metal and the lightweight and insulating properties of plastics. The new technique of 3D printing involves layer-by-layer metal growth in the electroplating process, as well as extrusion of a photopolymer composition, followed by UV light curing on the surface of a copper layer. Prints from this new type of 3D printer must exhibit strong adhesive bonding to prevent damage to the printed model. Therefore, mechanical tests were conducted to examine the adhesion of prepared photopolymer compositions to copper sheet coated with electroplated metal and to regular copper sheet in order to compare the obtained values. Analyzing the test results, it can be concluded that the structure of electrodeposited copper significantly improves the adhesive bond strength.
