To obtain a spouted-pouch package having a high degree of deoxidation by a method in which even a liquid filling which readily lathers can be packed while being inhibited from lathering. [MEANS FOR SOLVING PROBLEMS] A before-packing deoxidation step (1) is performed before a liquid filling is packed into a pouch. The step (1) comprises: a vacuum step (1-1) in which the pouch is evacuated under vacuum; an inert-gas blow step (1-2) in which an inert gas is blown into the pouch after the vacuum step; and a gas-diminishing vacuum step (1-3) in which the gas in the pouch after the inert-gas blow step is discharged under vacuum to diminish the gas in the pouch to a given amount. Thereafter, the pouch is evacuated in a second before-packing evacuation step (2-1) and then packed with the filling. After the packing, gas replacement is conducted.

The biodiesel hydrodeoxygenation technology is characterized in that a fixed bed reactor is adopted in the technology and filled with a hydrodeoxygenation catalyst, and the catalyst contains a carrier and active ingredients; the carrier is heteroatom Co2+ -doped MCM 41 in a synthesized skeleton structure; the active ingredient is a mixture of dimolybdenum nitride Mo2N, tungsten nitride W2N, molybdenum carbonate Mo2C and tungsten carbonate WC; the reaction conditions of the fixed bed reactor are as follows: the reaction temperature is 300-450DEG C, the hydrogen pressure is 2.5-3.5MPa, the hydrogen-oil volume ratio is 500-800, and the volume idle speed is 1.0-2.5h / l. By adopting the technology, the higher deoxygenation rate (more than 99.8%) of the biodiesel can be controlled in hydrodeoxygenation, and the catalytic activity after continuous running for 500 hours is obviously reduced.

Low-rank coal alcoholysis deoxidization method
The invention discloses a low-rank coal alcoholysis deoxidization method, which comprises the following steps of weighing 1 part by weight of dry basis low-rank coal and 3 to 10 parts by weight of absolute ethyl alcohol, uniformly mixing the low-rank coal and the absolute ethyl alcohol, and pouring the mixture into a high-pressure reactor; charging N2 with purity of more than 99 percent into the sealed high-pressure reactor to remove oxygen from the reactor, wherein the stirring speed in the high-pressure reactor is 300 to 400rad / min, the heating speed is controlled to be 5 to 10 DEG C per minute, and the temperature is maintained for 30 to 120 minutes after the reaction temperature reaches 220 to 300 DEG C; cooling the high-pressure reactor to room temperature, taking out a reaction product, performing vacuum suction filtration to obtain filtrate and residues respectively, and performing vacuum drying on the residues to obtain deoxidized coal. According to the method, high deoxidization rate can be achieved under the conditions of low temperature and pressure, the production cost is lowered, and the quality of lignite is improved.
