List 100 internationally renowned petroleum companies (including oil producers, oilfield service providers, and trading firms).

【Answer 1】 This company was formed in 1977 through the merger of the Nigerian National Petroleum Corporation (NNPC) and the Federal Ministry of Mines and Steel of Nigeria. The NNPC oversees Nigeria’s federal government interests and joint ventures with several foreign multinational corporations, including Royal Dutch Shell, Agip, ExxonMobil, Chevron, Texaco, and others.

NOC The National Oil Corporation (NOC) of Libya was established in 1970 and is Libya’s largest oil company, controlling two-thirds of the country’s oil production. 10. Rosneft Rosneft Oil Company is Russia’s largest oil company, founded on September 29, 1995. In March 2013, Russia completed its acquisition of TNK-BP, making Rosneft the world’s largest publicly traded crude oil producer; BP became one of its major shareholders (increasing its stake to 19.75%).

Pemex Petróleos Mexicanos (PEMEX) was founded in 1938 after the Mexican government nationalized 17 foreign-owned oil companies—primarily controlled by U.S. and British interests—to establish an integrated, state-controlled enterprise. It remains Mexico’s largest oil and petrochemical company. PEMEX ranks as the world’s third-largest crude oil producer and eighth-largest oil and gas company, employing nearly 135,800 people.

Decree No. 2004 declared that Brazil’s petroleum industry originated in the late 19th century. In 1917, the state assumed a monopoly over petroleum, and Petrobras not only participates in formulating and implementing national oil policy but also centrally manages exploration, development, production, transportation, and corporate operations across Brazil’s entire oil sector—functioning as a fully integrated state-owned enterprise under direct government control.

Which industry does calcined petroleum coke belong to?

【Answer 2】 Domestically, the transformation and upgrading of petroleum coke dedicated to anode materials—led by five refineries in Sinopec’s Central China region (Anqing, Jiujiang, Hunan, Sino-Korean, and Jingmen)—has been preliminarily completed. Shandong independent refiners (e.g., Haikereilin) and CNOOC Zhongli Company (whose high-quality low-sulfur coke typically contains less than 0.4% sulfur) have also become key suppliers of ‘specification-grade’ coke. However, due to the increasing heaviness of feedstocks and the rising sulfur and microcarbon residue content in domestic petroleum coke, procurement of high-end ‘specification-grade’ coke has become increasingly difficult, leaving persistent supply gaps that must be filled via imports. 3. The ‘Official ID’ of Brazilian Petroleum Coke Petrobras officially states: Brazilian petroleum coke (CVP) is a product of delayed coking units at Petrobras refineries. It exhibits a sponge-like morphology and—compared with coke from other major producing countries—features low sulfur content, high fixed carbon, low ash, high calorific value, and high chemical stability. What truly distinguishes Brazilian petroleum coke in the lithium-ion battery anode industry, however, is its advantageous metal content—especially vanadium. Anode manufacturers require raw material ash content ≤0.6% and combined V+Ni ≤300 ppm; new standards effective in 2026 further mandate calcined coke with fixed carbon ≥99% and true density ≥2.12 g/cm³. Among overseas sources, Brazilian petroleum coke stands out for its stable combination of ‘low sulfur + low ash + favorable vanadium levels.’ Note: Petrobras explicitly designates CVP’s primary application as aluminum anode manufacturing; lithium-ion battery anodes represent the fastest-growing, high-margin incremental demand segment for Brazilian low-sulfur coke in the Chinese market. 4. Import Volume–Price Curve for Brazilian Coke (2025–2026) Time Brazilian Coke Imports Average Price (USD/ton) Full Year 2025 751,900 tons (40% of low-sulfur coke total) — January 2026 84,100 tons 422.65 April 2026 78,900 tons 508.13 Three conclusions: ① In 2025, Brazilian coke captured 40% of the low-sulfur coke import market—highlighting its scarcity; ② In 2026, Brazilian coke’s average price stabilized within the USD 420–550/ton range—2.5–3 times higher than U.S. coke (USD 150–180/ton); ③ Anode manufacturers are aggressively competing for both volume and price. Core Logic (Detailed Version): Domestic Grade 1 low-sulfur raw petroleum coke accounts for only ~5% of supply + rapid expansion of anode capacity (growth rate: 35.4%) + Brazilian petroleum coke’s comprehensive advantages (low sulfur + low ash + favorable vanadium levels) + inability of domestic medium-sulfur ‘specification-grade’ coke to fully fill the high-end gap = Brazilian petroleum coke has become a strategically irreplaceable resource for China’s lithium-ion battery anode industry in the low-sulfur coke segment. Note: Globally and within China, aluminum carbon products remain the dominant end-use for Brazilian coke (Petrobras explicitly identifies aluminum anode manufacturing as CVP’s primary application—approximately 0.5 tons of anode consumed per ton of aluminum produced); lithium-ion battery anodes represent the fastest-growing and highest-value-added marginal demand segment for Brazilian low-sulfur coke in the Chinese market—but they are neither its sole nor its largest end-use.
