柴油十六烷值改进剂对市场存在的重要意义?

  十六烷值是柴油机自燃的一个重要指标,它对柴油机的冷启动、废气排放、燃烧噪声等性能有很大的影响。安阳豫化工有限公司,有限公司,针对国内外主要炼油企业开发和生产的柴油十六烷即兴表演剂,采用国际上广泛使用的硝化反应过程,使用军事生产工厂组织生产的主要成分是烷基硝酸酯,提高柴油的十六烷数量。

  Cetane number is an important index of diesel engine self ignition, which has a great influence on the cold start, exhaust emissions, combustion noise and other performance of diesel engine. Anyang Yu Chemical Co., Ltd. adopts the nitrification reaction process widely used in the world for the improvisation agent of Diesel Cetane developed and produced by major domestic and foreign refineries. The main component of the production organized by the military production plant is alkyl nitrate, which improves the cetane quantity of diesel oil.

  根据现有的原油加工工艺,直馏柴油的十六烷值一般大于50,可以满足高速柴油机对燃烧性能的要求。为了提高柴油的收率,采用催化裂化柴油,而催化裂化柴油十六烷值较低,一般在30~40之间,燃烧性能较差。为了提高柴油质量,炼油企业应采用合理的加工工艺和配合比来提高柴油十六烷值。通过添加柴油十六烷值改进剂来提高柴油十六烷值的成本,工艺简单,操作方便,为石油炼制企业带来了可观的经济效益。

  According to the existing crude oil processing technology, the cetane number of straight run diesel oil is generally greater than 50, which can meet the requirements of combustion performance of high-speed diesel engine. In order to improve the yield of diesel oil, FCC diesel oil is used, while the cetane number of FCC diesel oil is low, generally between 30 and 40, and its combustion performance is poor. In order to improve the quality of diesel oil, the refinery should adopt reasonable processing technology and mixture ratio to improve the cetane number of diesel oil. By adding Diesel Cetane Number Improver to increase the cost of Diesel Cetane Number, the process is simple and the operation is convenient, which brings considerable economic benefits for oil refining enterprises.

  柴油机的燃烧过程是一个短而复杂的物理化学过程,它分为四个阶段:滞燃期、快燃期、慢燃期和补燃期。十六烷值改进剂的作用机理是缩短柴油的着火延迟期。柴油十六烷值改进剂在柴油燃烧过程中提供自由基化合物,参与柴油的氧化和分解。与氧化自由基为中心,连锁反应可以大大降低柴油的自燃活化能,缩短点火延迟期的柴油,提高柴油的自燃柴油机,改善发动机冷启动性能,降低燃烧噪音和柴油污染排放。

  The combustion process of diesel engine is a short and complex physicochemical process, which is divided into four stages: delayed combustion, fast combustion, slow combustion and supplementary combustion. The mechanism of cetane number improver is to shorten the ignition delay of diesel fuel. Cetane number improvers provide free radical compounds in the combustion process of diesel fuel, and participate in the oxidation and decomposition of diesel fuel. With oxidation free radicals as the center, the chain reaction can greatly reduce the activation energy of self ignition of diesel, shorten the ignition delay period of diesel, improve the self ignition diesel engine of diesel, improve the cold start performance of engine, reduce combustion noise and diesel pollution emissions.
