Biomass is one of the highly abundantrenewable resourcesavailablethat can be converted into several high-value-added products, includingchemicals, biofuels, and advanced materials. To achieve net-zero emissionsand improve biomass application, researchers around the world haverecently focused on expanding biomass processing techniques to value-addedproducts with the eventual goal of industrializing some of the products.In this review, we summarize lignocellulosic biomass derived furfural(FA) and its subsequent hydrogenation to furfuryl alcohol (FAL). Thiswork reviews the various types of hydrogenation catalysts and theirutility in the production of value-added products from FA. There willbe an increase in the demand for selective catalysts and process technologies,as well as an increase in the challenges during valorization, as theusage of biomass to achieve carbon neutrality increases. The reviewaims to provide a concise overview of the advancements in this fieldand the potential for sustainable FAL production. In this paper, wepresent a simple strategy for selecting catalyst systems and associatedprocess parameters that facilitate the highly efficient and selectivevalorization of FA to chemicals or fuel (bioadditives) for industrialuse.

2-Methylfuran is a perfect green solution on the pathway of finding alternative fuels. We report here for the first time the continuous production of 2-methylfuran (2-MF), a sustainable biofuel from biomass-derived furfural (FFA), over an industrial Cu-ZnO-Al2O3 (CZA) catalyst. The modified coprecipitation method provides a uniformly dispersed crystalline structure to the synthesized catalysts, along with intended copper (Cu) loading achievement. Different Cu loadings affect the catalytic behavior and activity. Hence, CZA catalysts with two Cu loadings of 9.8 and 4.7% were studied in detail, denoted as C1 and C2, respectively. The catalysts were characterized via XRD, N-2 adsorption, H-2-TPR, NH3-TPD, XPS, ICP-MS, and TEM. Remarkably, the prepared catalysts demonstrate balanced acid sites with mesopores, a high surface area and pore volume, and better controlled nanoparticle size promoting catalytic activity. TEM and H-2-TPR studies reveal a better Cu dispersion. Existence of Cu2+ and Cu (+) even after reduction by XPS study proves the efficiency of the synthesized catalysts. Furthermore, TGA indicates the stability of CZA catalysts. To understand catalytic activity and selectivity, the investigation was carried out in a packed-bed fixed-bed stainless steel reactor. Better physiochemical properties result in high FFA conversion of 33.8% and selectivity of 99.6% for 2-MF. No side products were formed during reaction otherwise improbable via the continuous method. Compared with available literature, the CZA catalyst was found to exhibit superior catalytic performance. The reaction kinetics of furfural hydrogenation to 2-methylfuran was investigated, and it was found that the reaction order is high, and the activation energy was 61.2 kJ/mol. The rate constant k clearly obeyed the Arrhenius law from 180 to 220 degrees C. In addition, evaluation of reaction kinetics also indicated the absence of ring hydrogenation and decarbonylation products, which is difficult to achieve. Finally, the process shows significant economic viability, which resulted in the minimum levelized production cost for 2-methylfuran of 173,068.16 \$/ton with 78.32% overall energy efficiency.

In this study, we investigated the conversion of sucrose to 1,2-propanediol (1,2-PDO) using various Cu-La metals supported on activated carbon (AC), a versatile support known for its hydrophobicity and high surface area. Among the catalysts tested, 6% Cu-20% La/AC demonstrated the highest activity, achieving a 72% yield of 1,2-PDO under optimal reaction conditions of 200 degrees C, 40 bar H2, and 6-h reaction time. Comparative studies using cellulose, sucrose, glucose, and fructose as substrates identified sucrose as the most favorable feedstock for 1,2-PDO production. Detailed catalyst characterization (XRD, TEM, FE-SEM, TPR, TPD, XPS) revealed that the high dispersion, presence of metallic copper, and synergy between Cu and La, along with the presence of optimal acidic and basic sites, were responsible for the catalyst's high selectivity of 1,2-PDO. Additionally, the effect of different supports, including HY, NaY, HZSM-5, NaZSM-5, gamma-Al2O3, and AC, on sucrose conversion was examined, with AC showing superior performance. The catalyst's reusability was also assessed.Graphical abstractInvestigation of Cu-La metals supported on activated carbon for the catalytic conversion of sucrose to 1,2-propanediol, with an emphasis on choice of support, feedstock selection, catalyst performance, and stability under optimized reaction conditions.
