摘要

资源是人类社会发展的物质基础，环境是人类赖以生存的基本条件。采用合理的手段利用资源保护环境是当今化工研究的重点，也是人类面临的挑战。

基于对我国国情及资源种类考虑，研究MTO技术将是我国化工生产烯烃产物的理想道路。通过调查和查阅有关的数据表明，MTO技术中的反应装置的设计是目前较为前沿的技术，大多都是将FCC中的流化床反应器应用于该工艺中。

本设计的内容主要包括反-再系统的工艺计算、反应器的结构设计及其强度校核三个部分。首先利用Aspen plus软件对反—再系统进行模拟计算，得到物料及热量衡算结果。再根据计算结果并结合大连物化所研究的催化剂SAPO-34的反应条件及相关数据，对MTO过程中的流化床反应器和再生斜立管进行工艺设计，得出流化床反应器的高度和直径。最后依据反应物和产物的物理性质、化学性质、反应条件及设计参数，对反应器进行结构设计及强度校核。最终设计得到一套20×104t/a的MTO反应装置。

关键词：MTO，流化床反应器，SAPO-34催化剂，结构设计。

Abstract

Resource is the material basis of social development, the environment is the basic condition of survival. Reasonable of resources is the focus in the study of chemical industry, is also face the challenge of human beings.

Based on China’s national conditions and resource type consideration, research MTO technology will be the country’s chemical production olefins product ideal road. Trough the survey and consult relevant data show that the reaction in the device MTO technology design is now more forward technical, mostly in the FCC is reaction device used in the fluidized bed process.

This design content mainly includes the process calculation, the system to the reactor structure design and strength check three parts. First, the Aspen plus software for simulate reaction regeneration system, and get material and heat calculation results. Then through the calculation results and combining with the catalyst SAPO-34 reaction conditions of Dalian institute of chemical and the related data, to the MTO process of fluidized bed reactor and regeneration inclined stand pipe process design, draw the fluidized bed reactor height and diameter. The last, based on the physical properties of reactant and product, chemical properties, the reaction conditions and the design parameters, the structure design of reactors and strength check. The final get a set of 20×104t/a reaction of the MTO device.

Keyword: MTO, fluidized bed reactor, SAPO-34 catalyst, structure design.
