Abstract

Изобретение относится к способу получения этиленгликолевого эфира из оксалата со следующей формулой:Секции катализации содержат А) катализатор А на медной основе для гидрирования оксалата и В) катализатор В на основе цеолитного молекулярного сита для этерификации этиленгликоля. Секции катализации располагаются в следующем порядке: 1) катализатор А образует секцию А, а катализатор В образует секцию В, которая расположена ниже по потоку относительно секции А; 2) композитный катализатор получают физическим смешиванием гранулированных катализаторов А и В; 3) интегрированный катализатор получают путем формования смеси порошка катализатора А и порошка катализатора В и/или 4) в случае, когда катализатор А и катализатор В интегрированы в один катализатор, катализатор А является нанесенным катализатором, а катализатор В является носителем катализатора А. Молярное соотношение SiO/AlOв катализаторе В 20-200. Данный способ осуществляется за один этап, технология проста, расходы на оборудование низки, эффективно снижены расходы на производство этиленгликолевого эфира и при этом конверсия оксалата и селективность по этиленгликолю высоки. Настоящее изобретение также включает способы получения катализаторов и их комбинирование.The invention relates to a process for producing ethylene glycol ether from oxalate with the following formula: Catalyst sections contain A) a copper-based catalyst A for oxalate hydrogenation and B) a zeolite molecular sieve catalyst B for ethylene glycol esterification. The catalytic sections are arranged in the following order: 1) catalyst A forms section A, and catalyst B forms section B, which is located downstream of section A; 2) a composite catalyst is obtained by physically mixing granular catalysts A and B; 3) an integrated catalyst is obtained by forming a mixture of catalyst A powder and catalyst B powder and/or 4) in the case where catalyst A and catalyst B are integrated into one catalyst, catalyst A is a supported catalyst and catalyst B is a carrier of catalyst A. Molar ratio SiO/AlO in catalyst B 20-200. This method is carried out in one step, the technology is simple, the cost of equipment is low, the production cost of ethylene glycol ether is effectively reduced, and the oxalate conversion and selectivity to ethylene glycol are high. The present invention also includes methods for producing catalysts and their combination.
