Natural fruit and vegetable ferment beverage, and preparation method thereof

The present invention discloses a natural fruit and vegetable ferment beverage, and a preparation method thereof. The preparation method for the ferment beverage comprises: adding freshly-squeezed fruit and vegetable juice to marine fish skin collagen peptide; adopting the resulting mixture as a fermentation substrate; carrying out dilution, slurry mixing and sterilization, and then adopting a direct vat and freeze-dried type lactic acid starter to carry out fermentation; stopping the fermentation after 7-11 days until the pH value is 4.3; adding a supplementary feed and carrying out sterilization; then adding high-activity dried yeast to carry out fermentation; stopping the fermentation after 5-7 days until the pH value is 4.0; after storing the fermentation broth at the low temperature, carrying out homogenization, concentration, centrifugation, blending, sterilization and bulking to finally prepare the novel natural fruit and vegetable ferment beverage. According to the ferment beverage of the present invention, the stepwise fermentation is adopted for the freshly-squeezed fruit and vegetable juice by using the lactic acid bacteria and the yeast; the marine fish skin collagen peptide is added to promote the growth and the metabolism of fermentation bacteria, such that metabolic products of nutritional ingredients in the natural fruits and vegetables are rich so as to provide a beneficial nutrition and health effect.

Catalyst for preparing aromatic hydrocarbon through methanol conversion as well as preparation method and application thereof

The invention discloses a catalyst for preparing aromatic hydrocarbon through methanol conversion. The catalyst comprises a component A and components B, wherein the mass ratio of component A to components B is 0.25-4; the component A is a modified zeolite molecular sieve and comprises 80-99wt% of molecular sieves and 1-20wt% of molecular sieve modifiers; the components B are oxide loaded metallic elements and halogen and comprise 85-95wt% of oxide, 0.5-10wt% of total metallic elements and 0.1-5wt% of halogen; and the component A and the components B are formed through squashing or extruding after being mixed uniformly. The catalyst has the following characteristics that: (1) the total recovery of benzene, toluene and xylene is higher and selectivity is high; (2) the raw material treatment capacity is large; (3) the non-aromatic hydrocarbon liquid product can serve as the solvent oil or gasoline component; (4) C4 hydrocarbon and non-aromatic hydrocarbon liquid phase products in the gas phase product can circularly enter into the catalyst bed layer, thus not only balancing the reaction heat but also improving the total recovery of the aromatic hydrocarbon; and (5) the catalyst has high activity and long life.

Anti-oil and fire-retardant chlorinated polyethylene sheath material with good weather resistance and preparation method thereof

The invention relates to an anti-oil and fire-retardant chlorinated polyethylene sheath material with good weather resistance and a preparation method thereof. The sheath material uses chlorinated polyethylene rubber as main raw material and adds chlorosulfonated polyethylene rubber, triallyl isocyanurate, 1,3-bis (tert-butyl peroxide isopropyl) benzene, trioctyl trimellitate, carbon black, antioxidant 1010, ultra-fine talc powder, antimony trioxide, and high-activity magnesium oxide R-150 according to ratios; the preparation method is as follows: at first, mixing part of the auxiliary agents, then mediating, internal mixing, open mixing, granulating and extruding are carried out on the mixture to form cables, thus the cables are obtained. In the formula, high temperature resistant plasticizer is utilized, various auxiliary agents with appropriate proportions are added into the formula, so that chlorinated polyethylene rubber cable material can reach a high temperature of 105 DEG C, and can be used at the lowest temperature of minus 50 DEG C. The sheath material has the advantages of good anti-aging property, excellent electrical insulation and mechanical property, environmental protection and high flame resistance, thereby being suitable for cold and oil-contaminated severe environment and transmission and distribution circuits of which the current-carrying capacities are large and the rated voltages are at or below 450/750V. Meanwhile, compared with traditional chloroprene rubber cable material, the sheath material has the characteristics of low cost, fast extruding speed and high output benefit.
