Methaforming Cuts Costs of High-Octane Gasoline...

摘要

The New Gas Technologies-Synthesis (NGTS) Methaforming process removes sulfur and converts naphtha and methanol into a high-octane gasoline blendstock with low benzene, releasing hydrogen. Methaforming uses a proprietary zeolite catalyst in a process flow scheme that is similar to naphtha hydrotreating. The methanol is dehydrated in a highly exothermic reaction, releasing the methyl radical for alkylating benzene into toluene. As in reforming, the normal paraffins and naphthenes are converted to aromatics, releasing hydrogen in a highly endothermic reaction. The methanol is injected into the fixed-bed reactor in stages to balance reaction temperature and optimize the conversion. Unlike conventional reforming processes, Methaforming can tolerate sulfur content up to 500 ppm wt, reducing it by 90%.
