在种源培育与养殖标准化方面，吉林敖东同样走在行业前列。吉林敖东耗时数十年培育出国内首个以企 业命名的梅花鹿品种"敖东梅花鹿"，从遗传根源锁定原料纯正性与优良性状。其"梅花鹿高效养殖增值 技术"曾获国家科学技术进步奖二等奖。在养殖环节，吉林敖东坚守长白山核心产区，建立超350公顷的 GAP标准化梅花鹿养殖基地，存栏量近3000头，坚持传统自然采食方式，拒用预混饲料，同时实行鹿茸 原料"全流程闭环管理，坚决不外销"的原则，确保原料品质可控。 为实现梅花鹿疫病净化目标，吉林敖东投入巨大心力。在防疫设施升级上，企业累计投入超4600万元， 配备先进的防疫检测设备，建立全流程防疫监测体系；为进一步提升防疫安全性，吉林敖东出资千余万 元迁移职工家属区，划定专门的隔离缓冲带，从空间上切断疫病传播路径。通过一系列精准管控措施， 吉林敖东自2021年起便持续保持布病与结核病零阳性。 在养殖、种植环节，吉林敖东坚守长白山（603099）核心产区，建立超350公顷的GAP标准化梅花鹿养 殖基地，存栏量近3000头。其坚持传统自然采食方式，拒用预混饲料，并实行鹿茸原料"全流程闭环管 理，坚决不外销"的原则，将所有优质资源锁定在自有体 ...

Core Insights - The article discusses the characteristics, industrial chain structure, production patterns, consumption, trade dynamics, and future trends of the propylene industry, highlighting its significance in the global chemical market [2][3][4][11][17]. Group 1: Basic Characteristics and Industrial Chain Structure - Propylene, with the chemical formula C3H6, is a leading chemical product globally, characterized as an unsaturated olefin with a planar triangular molecular structure [2]. - The physical properties of propylene include a melting point of -185.2℃, a boiling point of -47.7℃, and a liquid density of approximately 0.5139 g/cm3 at 20℃ [2]. - The propylene industrial chain is structured as a pyramid, comprising upstream diverse supply, midstream global circulation, and downstream extensive applications, with each segment closely linked [3][4]. Group 2: Production Patterns and Technological Pathways - Global propylene production capacity has expanded significantly from 56 million tons per year in 2000 to 168 million tons per year by 2024, with a compound annual growth rate of 4.5% [6]. - Northeast Asia accounts for 57% of global propylene production, with China contributing approximately 80% of the capacity increase in this region [6]. - The Middle East has seen an 837% increase in production capacity from 2000 to 2024, leveraging low-cost oil and gas resources [6]. - North America has developed a propylene production belt along the Gulf Coast, utilizing shale gas resources and propane dehydrogenation (PDH) technology [7][9]. Group 3: Consumption and Trade Dynamics - Northeast Asia is the core region for propylene consumption, accounting for 51.9% of global consumption in 2023, with China being the primary market [11]. - The consumption structure in North America shows a stable 11.8% share, with high-end polypropylene products making up 40% of the region's consumption [11]. - Global propylene trade exhibits a "multipolar cycle" characteristic, with China reducing its import dependency from 14% in 2019 to 3.5% in 2024 [12]. Group 4: China's Propylene Industry - China's propylene industry has undergone three development phases, significantly altering the global supply-demand landscape [14][15]. - The current phase is characterized by a shift towards quality improvement, with a diverse production structure including PDH (35%), steam cracking (29%), coal-to-olefins (18%), and catalytic cracking (18%) [15]. Group 5: Future Trends and Challenges - Global propylene capacity is expected to continue expanding, reaching 180 million tons by 2026, with China accounting for over 45% of this capacity [17]. - The fluctuation in raw material prices, particularly the price difference between propane and naphtha, significantly impacts the economic viability of production methods [17]. - The industry faces challenges in balancing raw material security, cost control, and low-carbon transformation, which will reshape the competitive landscape of the international energy and chemical markets [17].
