1,2,4-Trimethylbenzene Transformation Reaction Compared With Its Transalkylation Reaction With Toluene Over USY Zeolite
Published 2020“…Kinetic parameters for the 1,2,4-TMB disappearance during the transalkylation reaction and in its conversion into isomerization and disproportionation products were calculated using the catalyst activity decay function based on time on stream (TOS). The apparent activation energies were found to decrease as follows: E-transalkylation > E-isomerization > E-disproportionation.…”

Renewable Energy Consumption and Carbon Emissions: Evidence from an Oil-Rich Economy
Published 2022“…The results reveal that renewable energy consumption has a negative impact on CO<sub>2</sub> emissions, while real GDP per capita has a positive effect. According to the findings, a 1% increase in renewable energy consumption leads to a 0.26% decrease in consumption-based CO<sub>2</sub> emissions, while a 1% rise in real GDP per capita leads to a 0.46% rise in consumption-based CO<sub>2</sub> emissions. …”

Evapotranspiration and water availability response to climate change in the Middle East and North Africa
Published 2021“…Outcomes reveal that the MENA region is indeed vulnerable to a surge in temperature, which can increase evapotranspiration losses and decrease water availability. Under the shared socioeconomic pathway (SSP2-4.5), the potential evapotranspiration (PET) has been projected to increase throughout the MENA region by up to 0.37 mm per year during the middle of the twenty-first century (2021–2050) and by up to 0.51 mm per year during the end of the twenty-first century (2071–2100). …”
