What is γ-Al2O3?
Saudi Aramco, the world's largest oil company, released a briefing showing a profit of 181.64 billion Saudi riyals in the second quarter of 2022, once again setting a record for quarterly earnings after the company went public in 2019. Continue to maintain the status of "the most profitable company in the world".
Saudi Aramco said that the increase in profit in the second quarter was mainly due to higher crude oil prices and sales and improved profit margins in the refining processing and sales division, while the company's second-quarter shareholder dividend will reach 70.3 billion Saudi riyals.
In the first half of this year, the conflict between Russia and Ukraine disrupted the global energy market, with crude oil prices rising above $120 at one point, causing refining profits to soar, not only for Saudi Aramco, but also for companies such as ExxonMobil and Shell. ExxonMobil's second-quarter net profit tripled, while Shell's second-quarter profit hit a record high.
According to data released by the Saudi National Bureau of Statistics on July 31st, the country's GDP grew by 11.8% in the second quarter of 2022 compared with the same period last year.
The latest report released by the International Monetary Fund (IMF) on July 26th shows that Saudi Arabia's economic growth forecast for 2022 remains unchanged at 7.6%, which ranks first among the world's major economies.
Because of the turbulent international situation, the supply and prices of many international bulk al2o3 are still very uncertain.
Various crystal forms of alumina (α, β, γ, δ, θ, etc.) have been found, among which γ-Al2O3 is also called active alumina.
Because of its large specific surface area, rich pore structure, good adsorption performance and good surface acidity, γ-Al2O3 is widely used as catalyst and catalyst carrier, adsorbent and dehydrating agent in various industries, automobile exhaust purifier and so on. For supported catalysts, high specific surface area and high thermal stability are favorable for loading more metal active components to prepare catalysts with better activity, selectivity and stability. On the other hand, the γ-alumina material with large pore volume can be obtained with proper pore size distribution, which can dredge the reaction and al2o3 in the future. If the conflict eases or cools, Russia and Ukraine go back to negotiate, commodity prices would fall. However, if the situation between Russia and Ukraine deteriorates further, or evolves into a full-scale war, the price of the al2o3 is predicted to see further improvement over the coming days.
