In the field of gasoline synthesis from renewable resources, highly integrated procedures with a minimum of process steps are mandatory to ensure efficient and sustainable production as well as marketability. In this context, oligomerization of ethylene to gasoline-type hydrocarbons is a viable option. The reaction has been studied employing a nickel silica-alumina catalyst and focusing on the influence of temperature, pressure, space velocity and time on stream on the product spectrum. Temperature and pressure largely influenced selectivity and intramolecular branching. The catalyst showed a stable performance during 170 h at 120 °C, 50 bar ethylene partial pressure and a space velocity of 8 h⁻¹. Under these conditions, ethylene conversion was steadily beyond 99%. Selectivity to C₆, C₈, C₁₀ and C₁₂ fractions was 15%, 25%, 18% and 10% while the average content of iso-olefins was 24%, 85%, 94% and 96%, respectively. The product selectivity slightly changed with increasing time on stream leading to less branched oligomers, probably due to slight catalyst deactivation. To evaluate the suitability of the C_5-12 fraction for fuel applications, it was hydrogenated and parameters like density, lower heating value, boiling behavior, vapor pressure, viscosity, flashpoint, autoignition temperature and oxidation stability have been determined.

在从可再生资源合成汽油领域，高度集成的程序和最少的工艺步骤是确保高效和可持续生产以及适销性的必要条件。在这种情况下，将乙烯低聚成汽油型碳氢化合物是一种可行的选择。该反应使用镍二氧化硅-氧化铝催化剂进行了研究，重点关注温度、压力、空速和流转时间对产物光谱的影响。温度和压力在很大程度上影响选择性和分子内支化。该催化剂在 120 ℃、50 bar 乙烯分压和 8 h ^-1空速下在 170 小时内表现出稳定的性能。在这些条件下，乙烯转化率稳定地超过 99%。_{对 C 6}的选择性、C ₈、C ₁₀和C ₁₂馏分分别为15%、25%、18%和10%，而异烯烃的平均含量分别为24%、85%、94%和96%。随着运行时间的增加，产物选择性略有变化，导致支化低聚物减少，这可能是由于轻微的催化剂失活。为了评估 C _5-12馏分对燃料应用的适用性，对其进行了氢化，并确定了密度、低热值、沸腾行为、蒸气压、粘度、闪点、自燃温度和氧化稳定性等参数。
