Design and Preparation of Succinic Acid-Based Metal-Organic Frameworks for CO_2 Adsorption Technology

The generation of syngas via gasification is accompanied by greenhouse gas emissions and certain impurities like tar. This is the major problem that makes the technology unattractive for commercialisation. Tar content present in the syngas limits its application as it causes damage to engines, while the CO2 that accompanies it adds to the climate issues when released to the atmosphere. In this short review, an overview of techniques used for tar abatement, CO2 capturing, and potential areas of CO2 utilisation were discussed.

“…According to the Natural Gas Industry Annual Review 2017, Malaysia faces a high CO2 gas presence. In 2011, the global average atmospheric CO2 reached 390.4 ppm surpassing the 390 ppm limit for the first time 2) . Following the excess in CO2 and H2S, a worldwide threat is impending, particularly the environment [3][4][5][6] .…”

Electrochemical Studies of Microbiologically Influenced Corrosion on API 5L X65 by Sulfate-Reducing Bacteria in CO_2 Environments

The current study explores microbiologically influenced corrosion (MIC) of carbon steel API 5L X65 with and without the presence of sulfate-reducing bacteria (SRB) in CO2 environments. The Electrochemical Impedance Spectroscopy (EIS), potentiodynamic polarisation and Field Emission Scanning Electron Microscopy (FESEM) techniques were employed to analyse the carbon steel's corrosion behaviour. The Rp values from the EIS signify lower values denoting the steel's greater corrosion rate. FESEM micrographs found a uniform corrosion on specimens without SRB whereas a pitting corrosion on specimens with SRB. The study concludes that SRB accelerate the corrosion progression due to MIC.

“…The use of electric transportation cars is considered a significant way to lessen dependence on fossil fuels, deliver more efficient operation, reduce global warming effects generated by carbon emissions 1) , solve the challenges of carbon-neutrality 2) , overcome the pollution 3) and emission from internal combustion engine 4) . As carbon emission had reached a serious level 5) , electric vehicles potentially play an important role to solve the energy and environmental problems 6) caused by the current public transportation system.…”

Electric Vehicles (EVs) are considered a significant way to minimize dependence on fossil fuel. As one of the most energy-consuming auxiliary components in EVs, air conditioning should enhance its performance and minimize the power and energy consumption. In this experiment, a modular air conditioner prototype with additional heat pipe components for an electric bus air conditioner has been successfully constructed. In this study, a modular AC system testing was carried out before and after using heat pipes at various ambient temperature conditions. The results reveal that the heat pipes utilization in the modular AC system for electric buses increases the cooling capacity by about 15%, and reduces the power input level of the AC system by about 28%. This has contributed to raising of the system's Energy Efficiency Ratio (EER) of around 30%, and the heat pipe's average effectiveness of 7,5%.
