摘要:
A process for converting gaseous alkanes to olefins, higher molecular weight hydrocarbons or mixtures thereof wherein a gaseous feed containing alkanes is reacted with a dry bromine vapor to form alkyl bromides and hydrobromic acid vapor. The mixture of alkyl bromides and hydrobromic acid is then reacted over a suitable catalyst at a temperature sufficient to form olefins, higher molecular weight hydrocarbons or mixtures thereof and hydrobromic acid vapor. Various methods are disclosed to remove the hydrobromic acid vapor from the higher molecular weight hydrocarbons, to generate bromine from the hydrobromic acid for use in the process, and to selectively form monobrominated alkanes in the bromination step.
摘要(中):
将气态烷烃转化为烯烃,较高分子量烃或其混合物的方法,其中含有烷烃的气态原料与干燥的溴蒸气反应形成烷基溴和氢溴酸。 然后将烷基溴和氢溴酸的混合物在足以形成烯烃,较高分子量烃或其混合物和氢溴酸蒸气的温度下在合适的催化剂上反应。 公开了各种方法以从较高分子量的烃中除去氢溴酸蒸气,以便在该方法中使用氢溴酸产生溴,并在溴化步骤中选择性地形成一溴化烷烃。
