我国氮肥工业的发展机遇和前景－兼论“缓释肥料草酰胺连续生产工艺及应用”简介

Development opportunities and prospects of China's nitrogenous fertilizer industry

摘要: 本文概述速效氮肥工业存在的问题和缓效氮肥草酰胺的优点；介绍发明专利“一种合成草酰胺连续工艺”技术内容：用气体分离技术直接从合成气分离提取合成氨所需合成气用于合成氨；用“CO气相催化合成草酸酯”技术合成草酰酯；用草酸酯与氨反应直接合成缓效氮肥草酰胺，取代现有氮肥工业“用中温和低温CO水煤气变换生产大量CO₂用于与氨合成速效氮肥尿素或碳酸氢铵”，填补国际氮肥工业无法大规模直接生产缓效氮肥的空白，促进氮肥工业进行产业结构调整和产品升级换代，大量生产缓效氮肥草酰胺用于农牧业生产，以提高肥效、减少氮肥的流失和浪费，达到节约资源和能源，减轻水源和环境污染，提高农牧业产品的产量和质量，为发展现代绿色生态农牧业生产，促进社会经济可持续健康稳定发展。

Abstract: In this paper, the existing problems of available nitrogen fertilizer industry and The advantages of slow-release nitrogen fertilizer oxalamidearesummarized;Description of the invention patent "a synthetic grass amide continuous process" technical content：Direct gas separation technology separation and extraction of the desired ammonia synthesis gas for ammonia from synthesis gas;With “CO gas phase catalytic synthesis of oxalate ester technology”synthetic oxalic acid ester，Directly with oxalic acid ester reaction with ammonia synthesis of slow release nitrogen fertilizer grass amide(oxamide),Can only replace the existing industrial production in mildwith CO in mild and low temperature shift in the production of a large number of CO₂，Used for quick nitrogen urea or ammonium bicarbonate and ammonia synthesis,Fill the international nitrogen fertilizer industry from mass production of slow release nitrogen fertilizer directly in the blank.Promote the nitrogenous fertilizer industry in industrial structure adjustment and product upgrading,A large number of production of slow release nitrogen fertilizer grass amide used for farming and animal husbandry production,In order to improve efficiency and reduce nitrogen loss and waste, to save resources and energy, Reduce water and pollution of the environment,　For the development of green and ecological farming and animal husbandry production, Improve product yield and quality, Promote social sustainable healthy and stable development.
