Abstract
With the development of the petrochemical industry, in foreign country ,the use of olefins have been extended from low carbon olefins to high-carbon olefins. A large number of C4fractions co-producted fron refineries and petrochemical plants,which is important resource of synthetic rubber , synthetic organic polymer materials, fine chemical products and basic organic chemical raw materials. Thereinto, the butene -1 is mainly used as comonomer to produce LLDPE and HDPE.According to different sources of raw materials，there are two kinds of methodsproducing butene-1,including separation of mixed C4andchemical synthesis methods (ethylene dimerization).since the costs of ethylene dimerization is two high, most of plant adopt the method of mixed C4separation to produce butene-1. The methods of separation of mixed C4is different due to the deprivation of butadiene and isobutylene of raw materials. The methods of separation of mixed C4include: molecular sieve adsorption, extractive distillation, chemical reaction separation. Currently, the method chemical reaction separation is widely used in all equipment, namely employ chemical reaction to deprivate butadiene and isobutene of C4fraction, and then employ precision rectification deprivate the other components beyond butene-1, obtain high purity butene-1 produce. In addition, the methods removal butadiene also include hydrogenation and combination of both. Methods to removal isobutene include: reaction of isobutene and methyl alcohol, isobutene hydration reaction, isobutene dimerization, isobutene ploymerization reaction(form low molecular ploybutylene) and a combination of two reactions.

摘要
随着石油化学工业的发展，国外对烯烃的利用已逐渐由低碳烯烃扩大到高碳烯烃。炼厂和石油化工厂联产大量C4馏分，它是合成橡胶、合成高分子有机材料、精细化工产品和基本有机化工原料的重要资源。其中，丁烯-1主要用作共聚单体生产LLDPE和HDPE。根据原料来源不同，生产丁烯-1的主要工艺方法有混合C4分离方法和化学合成方法（乙烯二聚），由于乙烯二聚原料成本高，因此大多采用混合C4分离方法生产丁烯-1。而混合C4分离方法又根据脱除原料中的丁二烯和异丁烯的方法不同而不同。C4馏分的分离方法主要有：分子筛吸附法、萃取精馏法、化学反应分离法。目前，各生产装置普遍采用的是化学反应分离法，即利用化学反应将C4馏分中的丁二烯、异丁烯脱除，再采用精密精馏把比丁烯-1轻或重的C4组分分离掉，得到高纯度的丁烯-1产品。脱除丁二烯的方法除萃取精馏外还有加氢法及二者的组合。脱除异丁烯的方法有：异丁烯与甲醇醚化反应法、异丁烯水合反应法、异丁烯二聚的叠合反应法、异丁烯的聚合反应法（生成中、低分子聚丁烯）以及两种反应的组合。
