The present invention belongs to the fields of Pu'er tea storage technology and quality improvement, and particularly relates to a Pu'er tea storage bin and a storage method. The Pu'er tea storage binstably contains five dominant micro-organisms of new aspergillus niger, bacillus subtilis, aspergillus niger, Blastobotrys adeninivorans yeasts, aspergillus tubigensis, etc., is combined with Kunmingdry storages and other conditions to contribute to a later transformation of Pu'er tea, is combined with appropriate storage conditions, helps accelerate the later transformation of the Pu'er tea andimproves the quality of the Pu'er tea.

A dry grind ethanol production process and system with front end milling method is provided for improving alcohol and / or by-product yields, such as oil and / or protein yields. In one example, the process includes grinding corn kernels into particles then mixing the corn particles with a liquid to produce a slurry including oil, protein, starch, fiber, germ, and grit. Thereafter, the slurry is subjected to a front end milling method, which includes separating the slurry into a solids portion, including fiber, grit, and germ, and a liquid portion, including oil, protein, and starch, then milling the separated solids portion to reduce the size of the germ and grit and release bound starch, oil, and protein from the solids portion. The starch is converted to sugar, and alcohol is produced therefrom then recovered. Also, the fiber can be separated and recovered. Oil and protein may be separated and recovered as well.

The invention relates to a catalytic conversion method for petroleum hydrocarbon. According to the method, raw oil contacts a catalyst in a reactor to carry out a reaction, wherein the catalyst is rich in mesoporous zeolite; a cracking reaction is performed under the following conditions: a reaction temperature is 500-750 DEG C, weight hourly space velocity is 100-800 h<-1>, reaction pressure is 0.10-1.0 MPa, a weight ratio of the catalyst to the raw oil is 1:100, a weight ratio of water vapour to the raw oil is 0.05:1.0; the spent catalyst and the reaction oil gas are separated; the spent catalyst is subjected to regeneration, and returns to the reactor, the reaction oil gas is separated to obtain a product, wherein the product comprises ethylene, propylene, propane, butane and arene-rich catalytic gasoline; the catalytic gasoline is subjected to selective hydrogenation, and enters an arene extraction apparatus to separate to obtain the target product of light arene; the raffinate oil, the propane and the butane are subjected to steam cracking to further produce ethylene and propylene. With the method provided by the present invention, the yields of the ethylene and the propylene are respectively 20.31 wt% and 31.67 wt%, the yield of BTX is 24.39 wt%.

The invention relates to a method for operating an internal combustion engine (10), in the exhaust gas section (13) of which is arranged at least one SCR catalytic converter (16), which is hit with a reagent that contributes to NOx conversion in the SCR catalytic converter (16), and to a device for implementing the method. At least one measure (NOx_nK_mod) is calculated for the NOx concentration (NOx_nK) downstream after the SCR catalytic converter (16). An NOx sensor (18), which is arranged downstream after the SCR catalytic converter (16), generates an exhaust gas sensor signal (S_nK) whichcorresponds to at least the NOx concentration (NOx_nK) and optionally, as a result of cross sensitivity, to a reagent slip (ms_Rea_nK).; A reagent signal (S_Rea), which determines the dosage of reagent, is influenced by a correction signal (d_ReaSP) as a function of the difference (D) and as a function of a measure for the temperature (te_Kat) of the SCR catalytic converter (16).

The invention relates to the field of disposable hygiene products, and discloses a reinforced structural diaper with a composite core, which includes a diaper body, and the diaper body is composed of an air-permeable surface layer, a diversion layer, a composite core body, and a leak-proof bottom layer. Bonded with degradable hot-melt adhesive, the composite core consists of a dust-free paper, an upper absorbent layer, an elastic layer, a lower absorbent layer, and a spun-bonded non-woven fabric from top to bottom, and the upper absorbent layer includes a middle area and a Anti-side leakage areas on both lateral sides of the middle area, the middle area has several upper absorption sections distributed along the longitudinal direction, each of the upper absorption sections is arranged at intervals, and the distribution density of the superabsorbent resin on the anti-side leakage area is greater than The upper absorbing section, the lower absorbing layer is longitudinally distributed with several lower absorbing sections, each of the lower absorbing sections is arranged at intervals, and the layers of the composite core are bonded by degradable hot-melt adhesives. It solves the problem that the existing paper diapers are easy to agglomerate, break and delaminate, and the hot melt adhesive used for bonding has good bonding effect and is degradable.
