How to generate electricity from car suspension?5 answersElectricity can be generated from car suspension systems using various methods. One approach is to utilize piezoelectric elements, such as Lead Zirconate Titanate (PZT), which can convert mechanical energy into electrical energy through electro-mechanical coupling. This can be achieved by placing piezoelectric stacks inside the suspension system, where the mechanical vibrations from the road excitation compress and decompress the piezoelectric disks, generating electrical energy. Another method involves using a power generating system that includes a sensing device and a permanent magnet device. The sensing device, consisting of a sleeve, sensing coil mounting support, and piston rod, detects the mechanical motion and induces electrical energy through electromagnetic induction. Additionally, an electric power generating apparatus can incorporate a valve structure to disconnect the suspension device from the energy recovery device when driving on rough roads, preventing damage to the system. These approaches offer potential for harvesting electrical energy from car suspensions, providing opportunities for low-voltage applications in daily life.
What are the ways for producing green ammonia?4 answersGreen ammonia can be produced through various methods such as plasma-electrocatalytic reaction systems, electrochemical, photocatalytic, thermochemical, and chemical looping processes. The plasma-electrocatalytic reaction system combines plasma-air-to-NOx and electrochemical NOx reduction reactions with a bifunctional catalyst, resulting in high NH3 yield rates and excellent FENH3. Electrochemical, photocatalytic, and thermochemical processes can also be used to produce hydrogen from ammonia, with catalysts such as Ni, Co, La, and perovskite catalysts showing potential for extracting hydrogen from ammonia. The Haber-Bosch process, although widely used, has limitations in terms of energy consumption and CO2 emissions, leading to the development of "green" ammonia synthesis methods such as electrocatalytic and photocatalytic approaches. Additionally, the use of renewable energy sources like sun and wind can enable the synthesis of green ammonia from nitrogen and water. Direct electrochemical nitrogen reduction with a hydrogen permeable nickel membrane/electrode is another approach for ambient condition ammonia synthesis, enabling carbon emission-free ammonia production.
How spent catalytic converter used again directy in automotive?5 answersSpent automotive catalytic converters can be used again in automotive applications through a process called recovery and recycling. The process involves the extraction of precious metals, such as platinum group metals (PGMs), from the spent converters using hydrometallurgical techniques like leaching and liquid-liquid extraction. The composition of the catalytic converters includes ceramic or metallic carriers, which contain PGMs like platinum, palladium, and rhodium. These metals play a catalytic role in the converters, facilitating the conversion of harmful exhaust gases into less harmful substances. The recovered PGMs can then be used to manufacture new catalytic converters or for other applications. The recovery process involves leaching the metals from the spent converters using acids like aqua regia or a mixture of HCl, H2SO4, and H2O2, followed by liquid-liquid extraction using an ionic liquid. This process allows for the separation and purification of the PGMs for reuse.
What is use of proceeds of green bond?5 answersThe use of proceeds of green bonds is to fund sustainable development projects and environmentally-friendly activities. Green bonds are issued to investors seeking fixed-income and the funds collected through these bonds are invested in green projects. The goal is to channel the proceeds of the bonds towards projects that address environmental impacts and promote a low-carbon economy. Green bonds can act as a commitment device, holding firms accountable to their environmental promises. They can also improve the environmental, social, and governance (ESG) performance of corporations, leading to increased profitability, growth, innovation, and responsibility. Additionally, the issuance of green bonds can benefit property developers in their sustainable life cycle management and continuous development of properties. The synergy between companies and green investors through green bonds is expected to improve the economy and maintain the balance of natural resources.
