bioethanol, etc ; crosslinking; pervaporation; polydimethylsiloxane; Show all 4 Subjects
Abstract:
... Polymeric membranes are in great demand for biofuels, and ultraviolet (UV)-induced crosslinking currently shows a controllable and ultrafast ability for their fabrication, whereas the weak compatibility between the photoinitiator (PI) and polymer remains a great challenge in the large-scale supply of membranes. Herein, we report a polydimethylsiloxane (PDMS) prepolymer simultaneously functionalize ...

Abstract:
... BACKGROUND AND OBJECTIVES: Cereal‐based bioethanol stillage, the main by‐product of industrial bioethanol production, is a potential substrate for fructans. However, the quantification of fructans in such complex sample matrices is still a challenge for the corresponding analytics to be overcome to allow for the identification and utilization of such unused fructan sources. Especially a possible u ...
bioethanol, etc ; ethanol production; feedstocks; solid state fermentation; Show all 4 Subjects
Abstract:
... The inefficient food processing and food leftover management strategies often lead to the wastage of untapped carbohydrate-rich feedstocks. The conversion of these feedstocks into bioethanol can mitigate the emission of greenhouse gases (GHGs) while providing a sustainable and eco-friendly method for disposing of food wastes. In light of the above, the current review scrutinizes various types of f ...

bioethanol, etc ; adsorbents; adsorption; energy; energy costs; ethanol; fermentation; Show all 7 Subjects
Abstract:
... Today, there are new technologies to produce bioethanol: one of them is the Pressure Swing Adsorption (PSA) process. This process has displaced other separation technologies due to the use of natural adsorbents and its methodology to obtain high purities with a lower energy cost. The aim of this work focuses on the optimization of the PSA process (experimental case) to obtain a higher recovery and ...

Abstract:
... It is known that any environmental remediation process must be approached as a system and that the transport of materials is key to determining its sustainability. The aim of this work is to establish how far it was possible to transport plant material from a phytoextraction process in such a way that the environmental gain of the remediation process is not compromised. In the absence of a general ...
bioethanol, etc ; biodiesel; bioenergy industry; biogas; deforestation; human population; lignocellulose; Show all 7 Subjects
Abstract:
... The ever-growing human population has resulted in the expansion of agricultural activity; evident by the deforestation of rainfoamrests as a means of acquiring fertile land for crops. The crops and fruits produced by such means should be utilized completely; however, there are still losses and under-exploitation of these produces which has resulted in wastes being mounted in landfills. These under ...

Abstract:
... This study focused on the techno-economic analysis of integrated polyhydroxyalkanoates (PHAs) and biofuels such as biohydrogen, bioethanol, and 2,3-butanediol production from food waste (FW). Based on previous literature studies, the integrated process was developed. The process plan produced 2.01 MT of PHAs, 0.29 MT of biohydrogen, 4.79 MT of bioethanol, and 6.79 MT of 2,3-butanediol per day, fro ...
bioethanol, etc ; catalysts; catalytic activity; ethylene; extrusion; industry; synergism; zeolites; Show all 8 Subjects
Abstract:
... The development of industrial catalysts is of crucial importance for practical uses. However, the use of extruded catalysts in industry is still limited because of a remarkably decreased catalytic activity when combining them with binders. This contribution illustrates the rational design of binder-free hierarchical ZSM-5 pellets and monoliths derived from zeolite@LDHs composites via extrusion and ...
bioethanol, etc ; ethanol; graphene oxide; hydrogen; molecular dynamics; oxidation; permeability; Show all 7 Subjects
Abstract:
... Graphene oxide (GO) membranes have received considerable interest for separation. The channels in GO membranes are in an atomic scale and thus it is challenging to unravel underlying separation mechanism via experiment. In this study, we model multilayered GO membranes with various channel widths (W) and oxidation degrees (O/C), subsequently simulate their performance for bioethanol (an ethanol/wa ...

Abstract:
... A carboxylate-type liquid zwitterion, OE₂imC₃C, has been recently reported as a unique solvent as a class of ionic liquids with distinctive properties and functions such as cellulose dissolution ability and low toxicity to fermentative microoganisms. Therefore, OE₂imC₃C first enabled successive conversion of biomass to bioethanol in the same reaction pot. However, the reagent, 1-bromo-2-(2-methoxy ...

Abstract:
... Sorghum hybrids can provide enhanced bioethanol yield if genetically complementary parents and progenies are developed using efficient crossing and selection methods. The objective of this study was to determine the combining ability of sweet stem sorghum genotypes, and assess heterosis among F1 hybrids for ethanol production and associated traits. Eight sweet stem sorghum lines and four testers w ...

Abstract:
... When making planning decisions, fluctuation in both product demand and yield for the bioethanol plant denotes an important factor to affect the results. In this paper, a mixed multi-stage stochastic optimization model is proposed to solve the production planning problem of a bioethanol plant with multiple raw materials simultaneously considering uncertain demand and yield. The multi-source uncerta ...

Abstract:
... 2,5-Dimethyfuran (DMF) and ethoxymetylfurfural (EMF) are the emerging potential bio-based fuel candidates that can replace petro-based ones. These fuels possess physicochemical properties comparable to those required in gasoline engine performance, but they have more favorable properties than bioethanol. In current, two types of input substrates, hydroxylmethylfurfural (HMF) and fructose-based fee ...

Abstract:
... The catalytic activity of anionic ruthenium complexes toward the transformation of bio-ethanol to 1-butanol and higher alcohols is found to be dependent on the imidazolium counterion. After the identification of a parallel reaction involving the catalyst in hydrogen evolution, conversion and selectivity are impressively boosted by the addition of p-benzoquinones as co-catalysts. The catalytic syst ...
