Embodiment Construction
[0029] Now take the primary bio-oil prepared by rapid pyrolysis and liquefaction as the raw material of rice husk as an example, a non-limiting example is described as follows, the calorific value of the primary bio-oil before upgrading is 23.6MJ / kg.
[0030] 1. The configuration contains Ni 2+ (0.1mol / L), Co 2+ (0.1mol / L), Mo 3+ (0.1mol / L) nitrate solution 100g, then add 10g HZSM-5 (Si / Al=28) to the solution, after stirring and dispersing, heat up to 72°C, add 6g solid NaOH to it, stir and react for 20min, The solution was filtered, and the obtained precipitate was dried at 105° C. and then sent to a muffle furnace for calcination at 800° C. for 2 hours to obtain a NiCoMo / HZSM-5 catalyst for use.
[0031] Take 100g of primary bio-oil and 2g of NiCoMo / HZSM-5 catalyst into the pressure-resistant reaction kettle and seal it with 2MPa H 2 The air in the upper layer of the reaction kettle was replaced, and the temperature of the system was raised to 400° C. After 40 minutes of ...
