摘要
本文介绍了以尿素为原料的低、常压法三聚氰胺生产工艺和对催化剂的严格要求。通过对硅胶、硅铝胶和γ Al2 O3 的对比和评价 ,指出了前两者的缺点和不足 ,并说明γ Al2 O3 是一种新型高效的催化剂 。
This paper introduces the requirements of making melamine with urea in low or normal pressure process.Through analysis,the shortcomings of silica gel and silica aluminum gel are given.And it is found that γ Al 2O 3 is a high efficient and new type catalyst,which shows the developing trend of its use in the melamine industry.
