摘要： A process for the disproportionation of toluene over a nickel-modified mordenite catalyst which has been pretreated with mild sulfiding procedure. The sulfur dose is employed in a minor amount relative to the nickel content of the catalyst. The modified mordenite catalyst is contacted with a sulfur-containing compound such as hydrogen sulfide or dimethyldisulfide (DMDS) under pretreatment conditions involving a temperature of at least 100° C. The sulfur-containing compound is employed in a relatively small amount to passivate only a minor portion of the active nickel sites. A toluene-containing feedstock is brought into contact with the pretreated catalyst under conditions effective for the disproportionation of toluene and a disproportionation product is removed from contact with the catalyst. The mordenite catalyst contains nickel in an amount within the range of 0.1-2 wt. %. The catalyst may contain another metal such as palladium or platinum, or a lanthanide series metal such as lanthanum or cerium. Pretreatment of the catalyst may be carried out by flowing a fluid pretreatment stream having a sulfur component into contact with the catalyst. The pretreatment stream comprises hydrogen sulfide or a thio compound which is converted to hydrogen sulfide under the pretreatment conditions.

摘要： The invention relates to the field of crop selection and crop breeding, particularly to selection methods for breeding colony varieties of crops involving self-pollination and normal cross-pollination. Selection methods include crossing male parents with female parents to obtain crop populations, wherein the female parents are individual plants in a segregation population or self-crossed descendants of early segregation generations, said segregation population obtained by hybridizing pairs of parental plants with different desired characteristics to produce population F1, and then hybridizing pairs of F1 one more time. The male parents are homozygous breeding lines, varieties, F1, heterozygous plants in the segregation generations or individual plants produced in the same manner as for the female group. Crop populations and colony varieties of crops display characteristics of consistency, stability, specificity, disease resistance, high yield, and high adaptability while permitting farmers to reserve seeds properly and companies to exploit pedigreed seed on a large scale.
