将石蜡转换成烯烃的制程及用于其中的催化剂;PROCESS FOR CONVERTING PARAFFIN TO OLEFIN AND CATALYST FOR USE THEREIN

摘要

本发明系关于用于将石蜡转换为烯烃之制程，该制程包含以下步骤：(a)提供含有至少一种石蜡(具有1至12个碳原子)及至少一种烯烃(具有2至12个碳原子)之烃原料；(b)在撑体(solid support)上提供含有至少一种VIA族及/或VIIA族过渡金属之催化剂；(c)藉由使催化剂与至少一种还原气体及至少一种氧化气体接触预处理该催化剂；以及(d)在200℃至600℃，较佳为320℃至450℃之温度范围内使烃原料与预处理之催化剂接触，且本发明系关于用于制程中的催化剂。; (b) providing a catalyst containing at least one Group VIA and/or Group VIIA transition metal on a solid support; (c) pretreating the catalyst by contacting the catalyst with at least one reducing gas and at least one oxidizing gas; and (d) contacting the hydrocarbon feedstock and the pretreated catalyst at a temperature in the range of 200℃ to 600℃, preferably 320℃ to 450℃
