    摘要: A rapid method for assaying collagen in meat and meat products. A sample of the material being tested is subjected to a controlled, incomplete hydrolysis of the amino acids with an acidified solution of stannous chloride in such a way that all of the tryptophan is completely destroyed but only a portion of the hydroxyproline is hydrolyzed. The percent collagen is correlated with the percent hydroxyproline, colorimetrically determined.

    摘要: This invention relates to an improved hydrotreating process for removing sulfur from naphtha and distillate feedstreams. This improved process utilizes a hydrotreating zone, an acid gas removal zone, and a pressure swing adsorption zone having a total cycle time of less than about 30 seconds for increasing the concentration of hydrogen utilized in the process.

    摘要: A multi component catalyst and catalytic cracking process for selectively producing C3 olefins. The catalyst comprises a first molecular sieve having an intermediate pore size, a second molecular sieve and, optionally a third molecular sieve having a large pore size. At least one of the channels of the second molecular sieve has a pore size index that is less than the pore size index of at least one channel of the first molecular sieve. The process is carried out by contacting a feedstock containing hydrocarbons having at least 5 carbon atoms is contacted, under catalytic cracking conditions, with the multi component catalyst. The catalyst finds application in the cracking of naphtha and heavy hydrocarbon feedstocks.

    摘要: In a process for reducing the Bromine Index of a feed containing a linear alkylbenzene and bromine-reactive olefinic hydrocarbon contaminants, the feed is contacted under conditions effective to remove bromine-reactive olefinic hydrocarbon contaminants with a catalyst comprising zeolite Y catalyst having an alpha value of about 2 to about 30. The feed will normally also contain benzene and linear paraffin remaining from the alkylation process used to produce the linear alkylbenzene.
