Abstract

The methanol-to-hydrocarbons (MTH) reaction was studied over a moderately acidic zeotype material, H-SAPO-5, at 350–450° C and with WHSV= 0.3–5h− 1. C3–C5 alkenes were the main products of reaction, followed by C6+ aliphatics. Conversion-selectivity plots from experiments conducted at various contact times revealed that coking did not influence product selectivity significantly. Steady-state isotope transient experiments (12CH3OH// ...
