The Utilization of N-Butanol to Olefins over Different Zeolite Structures

Abstract:

Bioalcohol is one of reliable renewable energy source in the future bioeconomy. Butanol is the next generation bioalcohol because of better quality comparing to lower-carbon alcohols. Its utilization to lower olefins opens the new route as chemical building blocks for polymer and value-added chemical production (instead of fossil fuel route). The n-butanol conversion to olefins was conducted over two different zeolite structures: ZSM-5 and SAPO-34. The small-pore 8-ring SAPO-34 produced exclusively C₄ in the products (more than 97%) and showed high selectivity to butene. The large-pore 10-ring ZSM-5 gave lower yield of C₄ and more classes toward larger hydrocarbon (C₅-C₁₂), which including aromatics and cyclic products. The SAPO-34 is suggested as promising shape-selective catalyst in the n-butanol conversion to butene product. The high purity butene can be used directly without further energy-consuming separation process.
