“…Hence, they used a 3° amine (NEt 3 in their case), together with ethanol in a proper ratio (NEt 3 :EtOH = 1:10), and obtained 100% yield of methanol (with respect to amine, Table , entry 16). A similar conclusion regarding the effect of alcohol was drawn by Kim-Lohsoontorn and co-workers, who observed that higher alcohols offered an increasing CO 2 conversion but decreasing methanol selectivity and yield. The mechanism of CO 2 capture and conversion in such amine/alcohol system is depicted in Figure .…”

“…As expected, step (3) was proposed to be the rate-determining step. Afterward, a similar route was also applied by Thompson, Kim-Lohsoontorn, , Nieminen, and Tsubaki (Table , entries 11–14 and 18). To enhance CO 2 adsorption, amines (including amino alcohols) were used to promote methanol yield by Mertens, Heldebrant, , and Lin, (Table , entries 15–17) as mentioned in Section .…”

The catalytic hydrogenation of esters and carboxylic acids represents a fundamental and important class of organic transformations, which is widely applied in energy, environmental, agricultural, and pharmaceutical industries. Due to the low reactivity of the carbonyl group in carboxylic acids and esters, this type of reaction is, however, rather challenging. Hence, specifically active catalysts are required to achieve a satisfactory yield. Nevertheless, in recent years, remarkable progress has been made on the development of catalysts for this type of reaction, especially heterogeneous catalysts, which are generally dominating in industry. Here in this review, we discuss the recent breakthroughs as well as milestone achievements for the hydrogenation of industrially important carboxylic acids and esters utilizing heterogeneous catalysts. In addition, related catalytic hydrogenations that are considered of importance for the development of cleaner energy technologies and a circular chemical industry will be discussed in detail. Special attention is paid to the insights into the structure–activity relationship, which will help the readers to develop rational design strategies for the synthesis of more efficient heterogeneous catalysts.

Technoeconomic Feasibility of Hydrogen Production from Waste Tires with the Control of CO₂ Emissions

et al. 2022

The worldwide demand for energy is increasing significantly, and the landfill disposal of waste tires and their stockpiles contributes to huge environmental impacts. Thermochemical recycling of waste tires to produce energy and fuels is an attractive option for reducing waste with the added benefit of meeting energy needs. Hydrogen is a clean fuel that could be produced via the gasification of waste tires followed by syngas processing. In this study, two process models were developed to evaluate the hydrogen production potential from waste tires. Case 1 involves three main processes: the steam gasification of waste tires, water gas shift, and acid gas removal to produce hydrogen. On the other hand, case 2 represents the integration of the waste tire gasification system with the natural gas reforming unit, where the energy from the gasifier-derived syngas can provide sufficient heat to the steam methane reforming (SMR) unit. Both models were also analyzed in terms of syngas compositions, H 2 production rate, H 2 purity, overall process efficiency, CO 2 emissions, and H 2 production cost. The results revealed that case 2 produced syngas with a 55% higher heating value, 28% higher H 2 production, 7% higher H 2 purity, and 26% lower CO 2 emissions as compared to case 1. The results showed that case 2 offers 10.4% higher process efficiency and 28.5% lower H 2 production costs as compared to case 1. Additionally, the second case has 26% lower CO 2 -specific emissions than the first, which significantly enhances the process performance in terms of environmental aspects. Overall, the case 2 design has been found to be more efficient and cost-effective compared to the base case design.

<p>The metal oxide composite is used to the microelectronic circuit, piezoelectric, fuel cell, sensor, catalyst, coating for preventing corrosion, and solar cell. The ZnO/CuO is one of the metal oxide composites. The combination of ZnO and CuO is the potential composite used to the catalyst and the anti-bacterial agent. The method used in this research was the electrochemical method in the acetate acid solution. The acetate acid solution used in this research is cheaper than the succinite acid used in the previous research. The electrochemical method has advantages due the easy to control and cheap. The composite resulted was analyzed by the XRD and the FTIR. The aims of this analysis are to know the crystallite phase, structure, and the functional groups of the particle resulted. The analysis showed that the ZnO-CuO composite can be resulted by the electrochemical method.</p>
