Disclosed are a pulverized coal preprocessing method and a pulverized coal gasifying method. The pulverized coal preprocessing method comprises the following steps: (1) performing pore broadening on pulverized coal to obtain preprocessed pulverized coal; (2) loading alkali metal ions into the preprocessed pulverized coal under an ion exchange condition to obtain alkali metal loaded pulverized coal. The method further comprises loading a chrome complex into the alkali metal loaded pulverized coal obtained in described step (2). In gasification, the pulverized coal loaded with alkali metal potassium and chrome catalysts obtained by the method has the advantages of high sulphur removal rate, high carbon conversion rate, short gasifying reaction time and high methane production.

A monolithic catalyst used for a carbon dioxide hydrogenation reaction and a method for preparing the same. The catalyst comprises a carrier, a coating, and active components. The carrier is a honeycomb ceramic. The coating and the active components are separately applied to honeycomb ceramic hole walls from inside to outside. Moreover, each of the honeycomb ceramic holes is divided into an upper segment and a lower segment, and different active components are separately loaded on the two segments. The method for preparing the monolithic catalyst comprises first applying a coating to a honeycomb ceramic by means of impregnation to obtain a coating-containing carrier, and then applying active components to an upper segment and a lower segment of the coating-containing carrier successively by means of impregnation to obtain the monolithic catalyst.

Disclosed are rice environmental conditional-lethal mutant gene osesl1, an encoding protein and use thereof The gene osesl1 has a nucleotide sequence shown as SEQ ID NO: 1 in the Sequence Listing. The encoding protein thereof has an amino acid sequence shown as SEQ ID NO: 2. After heading of osesl1 mutant rice, seed embryo lethal phenotype appears at 12 days after pollination, exhibiting darkening at the junction between embryo and endosperm. When an average temperature is below 22&#xb0; C., a seed embryo is normal; when the average temperature is above 28&#xb0; C., the seed embryo is lethal; when the temperature is between 22&#xb0; C. and 28&#xb0; C., the seed embryo is lethal under long daylight conditions (&#x3e;13 h) and normal under short daylight conditions (&#x3c;13 h). Use of the gene osesl1 in controlling seed embryo development of rice is further provided.

A method for systematically controlling rapid proliferation of cyanobacteria cells in lakes in spring is described. The method applies physical, biological and chemical methods in an integrated and synergistic manner and includes using flexible enclosures to close a control water area and using modified soil to adsorb and settle algal cells; coupling four technologies including algae control by fish, algae control by biological floating islands, algae inhibition by plants and algae control by microorganisms; and using HOto kW algae and using 40% FeCl+CaCOand 50% Ca(NO)to treat sediment. The method establishes a complete system for physical, chemical and biological control of algae, forms joint control of exogenous contaminants, endogenous contaminants and cyanobacteria, integrates physical, biological and chemical methods and optimizes systematic methods that are used synergistically.

Disclosed is a method for preparing a copper-zinc-based catalyst used in synthesis of methanol through COhydrogenation, and ultrasonic waves are used for control over crystalline phase's composition of a catalyst precursor. Further related to is a catalyst prepared by such a method. An amount of aurichalcite in an active catalyst precursor can be improved through the method, and the specific surface area of the metal copper in a reduced state catalyst is high. The catalyst presents high activity and hydrothermal stability, and promotes high space time yield of methanol in the synthesis of methanol through COhydrogenation.
