随着炼油工业的不断发展，催化裂化(Fcc)日益成为石油深度加工的重要手

段。在炼油工业中占有举足轻重的地位。FCC工艺是将重质油轻质化，目的产品

是汽油、柴油和液化气。由于转化率高，产品质量好，近半个世纪以来，FCC工

艺技术和生产规模都有了很大的发展。为了满足日益严格的环保要求和市场对烯

烃(特别是丙烯)需求的日益增长，催化裂化工艺技术也在进一步发展和改进。催

化裂化已经成为我国炼油工业的核心技术和石油化工企业经济效益的主要支柱。

作为炼油厂的核心加工装置，催化裂化也面临着越来越多的挑战。不断严格

的环保要求，主要是汽油规格的升级对烯烃和硫含量的要求以及烟气排放量的限

制；对产品需求比例的变化，如市场对柴油需求比例和数量的增加，即所谓的柴

油化趋势。这些都对现有的催化裂化装置与催化裂化的进一步发展形成很大的冲

击。而且除了采用新型有效的降低催化裂化汽油和柴油的硫含量外。还要考虑各

种技术的费用问题。

我国的催化裂化工业自60年代开始发展至今,装置数量和生产能力不断高,

据不完全统计,目前已有催化裂化生产装置近100套,总加工能力超过5000万t/a,

仅次于美国,居世界第二位。近几年渣油催化裂化得到了长足发展,不仅拓宽了FCC 原料来源,而且增加了汽柴油产量,大大加快我国重质油轻质化的进程

Answer 1

With the continuous development of oil refining industry, the Fcc catalytic cracking of petroleum deep processing becomes important

Section. In the refining industry plays a decisive role. The FCC process is appropriate, the purpose of heavy oil products

Gasoline, diesel oil and gas is. Due to the high conversion, product quality is good, nearly half a century, the FCC

Art technology and production scale have very big development. In order to meet the requirements of environmental protection and increasingly strict market of propylene

Hydrocarbon (especially propylene), the growing demand in catalytic cracking technology and further development and improvement. push

The refining industry has become a cracking of core technologies and petrochemical enterprise economic benefits of main pillar.

As the core of the refinery process device, catalytic cracking faces more challenges. Constantly strictly

The environmental protection request, mainly is the upgrade of gasoline specification requirements and sulfur content in olefins and flue gas emissions limits

: Demand for products, such as the ratio of diesel market changes and the increasing number of demand, the so-called wood

Oil tendency. All of the existing FCC catalytic cracking unit and the further development of the formation of the big rush

Strike. In addition to using new effectively lower the FCC gasoline and diesel outside the sulfur. Consider each

The cost of technical problems.

The FCC industry in China since the 1960's, device number and production capacity constantly high,

According to not complete count, existing catalytic cracking unit nearly 100 sets of production, processing capacity of more than 5,000 million t/a,

After the United States, ranking second in the world. In recent years, residue catalytic cracking had great progress, not only widen the sources of the raw materials, and FCC gasoline and diesel increased production in China, accelerate the process of heavy oil yields

Answer 3

With the continuous development of oil refining industry, FCC (Fcc) the depth of oil processing is increasingly becoming an important tool

Section. In the oil refining industry plays a decisive role. FCC process is the heavy oil light of the purpose of product

Gasoline, diesel and liquefied petroleum gas. Because of high conversion, product quality, nearly half a century, FCC work

Art technology and production scale has made great development. In order to meet increasingly stringent environmental requirements and market-ene

Hydrocarbons (especially propylene) the growing demand, catalytic cracking technology is also the further development and improvement. Urge

Of cracking has become the core technology of oil refining industry and petrochemical enterprises the main pillars of economic benefits.

As the core of the refinery processing units, catalytic cracking is also facing increasing challenges. Keep strictly

Environmental requirements, mainly gasoline specifications to upgrade to the olefin and sulfur content requirement and flue gas emissions limits

System; on the percentage changes in product demand, such as market demand for diesel the increase in the proportion and number of the so-called Chai

Oil trend. All of the existing fluid catalytic cracking unit and the further development of catalytic cracking great impulse formation

Attack. And in addition to effectively reduce the use of the new FCC sulfur content of gasoline and diesel outside. Also consider

Kind of technology costs.

Our FCC industrial development since the 60s so far, the number of devices and the continued high productivity,

According to incomplete statistics, there are already nearly 100 sets of catalytic cracking plant, the total processing capacity of more than 50 million t / a,

After the United States, ranking second in the world. In recent years, considerable progress has been residue catalytic cracking, FCC not only broadens the sources of raw materials, and increased production of gasoline and diesel, which greatly speed up the light of China's heavy oil process
