摘要
实验使用硬脂酸和氢气为原料,十二烷为溶剂,多微孔活性炭负载的金属钯为催化剂,在温度300±5℃和压力2.0MPa条件下,反应360min催化脱氧。结果表明,反应产物液相主要成分为正十七烷,而气相主要成分为CO2和CO.催化剂用量为3g时,初产品酸值最低,硬脂酸转化率和正十七烷选择性最高。
The catalytic deoxygenation experiments of stearic acid and hydrogen were performed for 360 rain in the presence of a solvent, dodecane, in a temperature range of 295-305℃ under 2.0 MPa of 25 vol. % hydrogen in argon using palladium supported on active and mesoporous carbon as a catalyst. The results showed, the main liquid-phase product was n-heptadecane, while the main gaseous products were CO2 and CO. The amount of catalyst is 3g, the acid value of firstlings is the lowest, conversion level of stearic acid and selectivity to n-heptadecane is the highest.
