Problems solved by technology

However, the effect of these inhibitors alone is not long-lasting, and the combined use of these five inhibitors not only has a good inhibitory effect (more than 90%, the highest can reach 99.5%), but also the methanogens are not easy to develop resistance, and this combination in There are no reports at home and abroad

Embodiment 1

[0021] Example 1: Analysis of the addition amount and use effect of methanogenic inhibitors

[0022] Considering that the compound fast-acting methanogenic inhibitor is a combination of five single inhibitors, this test analyzes and compares the five influencing factors in order to select the best one. In the experiment, due to the different states and conditions of the factors, the indicators may change, and these states and conditions of the factors are called levels. In this experiment, four states are selected for the five factors identified, that is, four levels. So choose L first 16 (4 5 ) orthogonal table (Table 1).

[0023] Add nitroethane, 2-nitroethanol, 2-nitro-1-propanol and 2-sodium bromoethanesulfonate in the fermentation bottle according to the effective addition amount of each level of the methane inhibitor component in table 2, to Dairy cows were used as experimental animals. Leymus chinensis and corn flour with a weight ratio of 1:4 and 4:1 were respectiv...

Abstract

The invention discloses a compound quick-action inhibitor against generation of methane in the technical field of greenhouse gas emission reduction. The preparation method comprises: 1) mixing nitroethane, 2-nitroethylalcohol and 2-nitryl-1-propyl alcohol by weight percent of 0-5:0-6:0-7 (the weight percents can not be 0 simultaneously) to formulate solution A; and 2) mixing pyromellitic formic diimide and 2-bromoethane sodium sulfonate by weight percent of 0-3:0-2 (the weight percents can not be 0 simultaneously) to formulate powder B. The compound quick-action inhibitor has very obvious effect in inhibiting methane, is especially applicable to inhibiting the action of generating methane in rumen, and is beneficial to protecting the environment and improving the utilization rate of feed energy of ruminants. The preparation method is simple, the operability is strong, and the inhibitor is applicable to livestock and poultry breeding feed processing, livestock and poultry manure excrement biogas treatment and municipal domestic waste biogas treatment, and has the efficiency up to over 90 percent in inhibiting the action of generating methane by microorganism, as well as high practical value.

Description

technical field [0001] The invention relates to a compound fast-acting methanogenic inhibitor, a preparation method and application thereof, and belongs to the technical field of greenhouse gas emission reduction. Background technique [0002] The currently used rumen methanogenesis inhibitors mainly include monensin, halides, nitro compounds, and plant extracts. Monensin is widely used and can reduce methanogenesis in animals by 30%, but the inhibitory effect is not long-lasting. Chloral hydrate is converted into chloroform in the rumen, which can reduce the generation of methane in the body, but chloral hydrate damages the liver, and long-term feeding can cause animal poisoning and even death; trichloroacetyl, trichloroethyl adipic acid and bromochloro The inhibitory effect of methane on methanogenesis was short-lived; sodium 2-bromoethanesulfonate (BES) was a potent CH4 inhibitor and did not inhibit the growth of other bacteria. The in vivo test found that its inhibitor...
