摘要：为了采用内过滤器实现炔化反应的连续化,在完善冷模研究后,首先对多种过滤介质在热模条件下进行筛选,以获得一种符合炔化反应工艺要求,并且过滤性能稳定持久的过滤介质。实验证明采用管式内过滤器可以解决在反应工艺条件下淤浆床连续化的气液固分离问题。通过对比淤浆反应器在连续及间歇操怍下的反应工艺及反应速率的一致性,从而建立了反应动力学模型,为进一步开发放大提供依据。
In order to develop a continuous process of 1,4—butynediol synthesis by using an internal filter, we, after the cold model teat, studied the behavior of various kinds of filter media under the reaction condition. A suitable filter media was obtained which accords with the requirement under the ethynylation reaction conditions. A kinetic study of ethynylation of formaldehyde over copper acetylide catalyst was carried out in a stirred slurry reactor. Experiments were conducted over the temperature range 70—90℃, formaldehyde concentration from 2.0 to 10.0 Kmol/m^3, acetylene partial pressure from 0.08 to 0.23 Mpa and catalyst concentration 70kg/m^3. The rate of reaction can be expressed as R=w*3.72*10^(20)*exp(—18720/T)*C_F^(0.9)*p_A^n If R_A≥0.18 MPa, n=0 If p_A<0.18 MPa, n=1.4 We also made comparisions of reaction process and reaction rates between continuous and batchwise process, the results obtained indicated that there are no appreciable differences and thus the reaction kinetic model can be used for the development and scale—up of reactor in continuous process.
