Adsorption is a separation process that has higher energy efficiency than others. Analyzing the nature of adsorbate and selection suitable adsorbent are key success in adsorption. The performance can be modified either physically or chemically to obtain effectiveness adsorption, this facilitated by using composite adsorbent. In study, we have conducted preparation polyvinyl alcohol (PVA)/zeolite/carbon composites. resulting composites dedicated for ethanol – water dehydration proposes. were...
Multilayer packaging (MLP) is widely used in food packaging. Due to the high consumption of MLP, amount MLP waste also increasing. However, this difficult be recycled and polluting environment. This study reports effect Fly ash addition on thermal conductivity properties multilayer composite. MLPs with different fly content (0, 5, 10, 20, 30 40 wt.%) were mixed using single screw extrusion form pelletized products. Furthermore, pellet was processed by compression molding at 260℃ 20 MPa for...
Introduction . Adsorption is a purification process with more efficient energy level than others. performance strongly influenced by the ability of adsorbent to be used; therefore, modification becomes very important key for that occurs. Methods In this study, preparation composite adsorbents was carried out combining polyvinyl alcohol (PVA), zeolite (Zeo), and activated carbon (AC) as precursors. The crosslinking fulfilled adding glutaraldehyde precursor mixtures followed supercritical...
Global energy issue is no longer a new topic. The expansion of production proven to show significant influence the fossil fuel modification by blending it with liquid renewable fuel, such as bioethanol. Bioethanol must achieve fuel-grade standard qualify gasoline, one specification have moisture content 1.0% v/v or less, regulated ASTM D4806. This parameter challenging achieve, because water-ethanol mixture will encounter azeotrope phenomenon when undergoes common distillation process and...

Biogas is one of the flammable natural gas. The most observed content biogas in this study methane (CH4), hydrogen (H2) and carbon dioxide (CO2). Therefore, can be developed used as an alternative energy. Nowadays, plant biodigester, producer, still very simple design. So, system design should to assist monitoring process production. In study, a which do data acquisition using MQ4 sensor methane, MQ8 MG811 also parameter influencing production such temperature, humidity pressure. Based on...
The increasingly widespread use of lithium-ion batteries for various electronic devices to their as electrochemical energy storage containers demands higher battery performance. One way improve performance is the cathode material. material can be improved by modifying surface LiFePO4 coating carbon on its so that conductivity and distribution increase. sources used carbonation metalorganic frameworks (MOF). Metal-azolate (MAF) are a member MOF in form complex compounds source modification In...
Bioethanol is considered as the most promising alternative fuel in future due to its abundant renewable sources. However, result of bioethanol production process using fermentation contains 70% v/v, and it still needs simultaneous purification process. One energy-efficient methods adsorption. Specifically, rate adsorption an important factor for evaluating performance. In this work, we have conducted polyvinyl alcohol (PVA), zeolite activated carbon adsorbents dehydration. This research aims...

The purpose of this research is to investigate the mechanical effects polypropylene using sorghum fiber as nucleating agent. Alkalization, bleaching, and acid hydrolysis are all used chemically modify fiber. This modified was then mixed with a polymer matrix for 10 minutes in rheomix at 100 rpm 165°C molded hot press. results study suggest that can improve crystallinity compatibility Furthermore, 23.44 MPa, optimum characteristics mixture micro fibrillated cellulose (MFC) from were achieved...
Epoxy-based composites are widely used in various applications due to their excellent mechanical properties and durability, but performance under prolonged UV exposure remains a critical concern. This study examines the impact of on physical, chemical, epoxy-silica microballoon over curing periods 0, 200, 400 hours. Results indicate that treatment increased density from 1.0073 g/cm³ 1.0129 g/cm³. SEM images showed reduction fragmentation epoxy microballoons, indicating stronger bonding. EDX...
Separators damaged by runaway heat in lithium-ion batteries (LIBs) are still a prominent safety concern utilizing these electrical energy storage systems. Efforts to improve separator performance or obtain new heat-resistant separators with high electrochemical urgently needed. In this study, composite PI-based membrane for the LIB has been successfully synthesized use as separator. The was crosslinked melamine and reinforced addition of montmorillonite form...
Lignocellulosic biomass, such as sorghum stalk fiber, has received a lot of interest reinforcement in polymer composites because its renewable nature, low cost, and potential environmental benefits. This is due to crystalline cellulose fibrils embedded hemicellulose, lignin, wax, other impurities the lignocellulosic fiber.
