1引言黑龙江石油化工厂催化裂化装置中产生的大量C4烃过去只简单的作为燃料。随着石油化工技术的进步,将副产的C4烃进行合理利用日益受到重视。目前,国内外广泛采用的正丁烯直接水合法制仲丁醇及仲丁醇脱氢制甲乙酮工艺为正丁烯的利用提供了一条新的途径。随着精细化工行业的
1 Introduction Heilongjiang Petrochemical plant catalytic cracking unit produced a large number of C4 hydrocarbons used in the past as a simple fuel. With the progress of petrochemical technology, it is paid more and more attention to the rational utilization of by-produced C4 hydrocarbons. At present, the widely used domestic and foreign direct method of n-butylene dehydration sec-butanol and sec-butanol to methyl ethyl ketone process for the use of n-butene provides a new way. With the fine chemical industry
