N-Doped mesoporous carbon extrudate with a major quaternary N species has been successfully prepared through direct carbonization of wheat flour/gluten with silica, which is a cheap and convenient method for scale-up production approach. The obtained carbon extrudate metal-free catalyst enables highly efficient production of vinyl chloride monomer through acetylene hydrochlorination, with a superior catalytic performance and excellent stability (>85% conversion and vinyl chloride selectivity over 99% at 220 °C).

小麦粉衍生的氮掺杂介孔碳挤出物，是乙炔盐酸盐化的优异无金属催化剂

通过将二氧化硅/小麦粉/面筋直接碳化，已成功制备了具有主要第四季N物种的N掺杂介孔碳挤出物，这是一种廉价且方便的大规模生产方法。所获得的无碳挤出物的无金属催化剂能够通过乙炔氢氯化高效生产氯乙烯单体，并具有优异的催化性能和出色的稳定性（在220°C时，转化率> 85％，氯乙烯选择性超过99％）。
