    • A process for the disproportionation of a toluene containing feedstock employing a nickel modified mordcnite catalyst comprising particulate mordenite having nickel dispersed throughout the catalyst particles to provide surface nickel and interior nickel within the mordenite crystal structure. The catalyst is pretreated Io selectively deactivate the surface nickel to provide a surface nickel content of reduced catalytic activity. The interior nickel lhus has a higher catalytic activity than the surface nickel. The feedstock is supplied to a reaction zone containing the catalyst to cause disproportionation of toluene in the feedstock to produce a mixture of benzene and xylene. The non-aromatic content of the product is less than the non-aromatic content of a corresponding disproportionation product which would be produced by the disproportionation of the fecdstream in the presence of a corresponding nickel mordenite catalyst which has not been pretreated.
    • 含有甲苯的原料的歧化的方法,该方法使用镍改性的莫氏体催化剂,其包含分散在整个催化剂颗粒中的镍的颗粒丝光沸石,以在丝光沸石晶体结构内提供表面镍和内部镍。 预催化剂催化剂选择性地使表面镍失活以提供具有降低的催化活性的表面镍含量。 内部镍镉具有比表面镍更高的催化活性。 将原料供给到含有催化剂的反应区,以使原料中的甲苯发生歧化,产生苯和二甲苯的混合物。 产物的非芳香族含量小于相应的歧化产物的非芳香族含量,其将通过在未进行预处理的相应的镍丝光沸石催化剂的存在下通过歧管进行产生。

    • The invention relates to the field of crops selection and breeding, particularly relates to the selection methods of self-pollination and normal cross-pollination in population, variety of crops. The selection method includes crossing male parents with female parents to obtain rice populations, wherein the female parents are individual plants which obtained from intercross parents which have different target characters, to produce F1, which is then intercrossed to produce individual plants of separated population, or are separated plants, which is obtained from the inbreeding of individual plant. The male parents are selected from pure line or variety or heterozygous progenies. The method includes five stages of cross, stable self-bred, determination, classification and population improvement. The population and variety have the characteristics of consistency, stability, specificity, farmers' reserving seeds properly, Company's exploiting pedigree seed in a large scale, and also have the characters of highly adaptability, disease resistance and high yielding. The breeding process reduces the dependence on exports' experience, and also adapts for selection for farmers.
    • 本发明涉及作物选择和育种领域,特别涉及种群,作物种类中自花授粉和正常异花授粉的选择方法。 选择方法包括将男性父母与女性父母交叉以获得水稻种群,其中女性父母是从具有不同目标特征的交叉亲本获得的单株植物,以产生F1,然后进行杂交以产生分离种群的单株植物,或 是从单株植物近亲获得的分离植物。 男性父母选自纯系或品种或杂合子代。 该方法包括交叉,稳定自我繁殖,测定,分类和种群改良的五个阶段。 人口和品种具有一致性,稳定性,特异性,农民适当保留种子的特点,公司大规模开发种子种子,具有适应性强,抗病性高,产量高的特点。 繁殖过程减少了对出口经验的依赖,也适应了农民的选择。
