ANS:C - aromatics

In the Edeleanu process, the extractor temperature is maintained at -20°C to reduce the aromatics content of kerosene. Here’s why:

• Edeleanu Process: This is a selective solvent extraction process used primarily to remove aromatic compounds from kerosene and other middle distillates. Aromatic compounds have higher solubility in selective solvents at lower temperatures.
• Temperature Control: By maintaining a low temperature (-20°C), the solubility of aromatic hydrocarbons in the solvent (usually furfural or phenol) is enhanced. This facilitates the selective extraction of aromatics from the kerosene stream.
• Purpose: The main objective of reducing aromatics in kerosene through the Edeleanu process is to improve the product quality by reducing the potential for smoke formation during combustion and meeting regulatory specifications for aviation fuels and other applications where low aromatic content is preferred.

ANS:A - China

Scientists from China discovered a new pattern of solar rotation using the CHASE (Chinese H-alpha Solar Explorer) satellite. Launched in October 2021, CHASE is China's first dedicated solar observation satellite, designed to study the Sun's dynamic activities and atmospheric layers. The discovery made by the CHASE satellite involves a novel pattern in the Sun's rotation, which could provide deeper insights into solar magnetic activity and its impact on space weather. By analyzing data collected from the satellite's observations, researchers identified previously unrecognized rotational behaviors that could influence solar phenomena such as sunspots, solar flares, and coronal mass ejections. This breakthrough in solar science helps to advance our understanding of the Sun's complex magnetic field and its broader effects on the solar system, including its interactions with Earth's space environment. The findings underscore the significance of international space missions and satellite technology in expanding our knowledge of solar dynamics and enhancing our ability to predict space weather events.
