And on the basis of mono-factor test, using COD decreasing rate and decolour rate as targets, six factors affecting catalytic effect were selected to proceed L9(34) orthogonal experiments. The conclusion of primary and secondary factors was drawn and the turn was : kind of catalyst-amount of catalyst-pH value-temperature-amount of H2O2-amount of air . The optimization were determined to be : initial pH value : 5.5 ; temperatare : 90 C; amount of H2O2: lml/400ml waste water ; kind of catalyst: AC3 ; inciting small amount of air ; amount of catalyst: 125g activated carbon to 500g stone .

First,the content of surfactant should be more than 18 percent and the content of anion surfactant should be kept in proper proportion to the content of nonionic surfactant. Second,the content of zinc naphthenate should be kept in directly proportional to the content of other surfactant. Third,the content of rosin shouldnt too higher and the content of oleic acid should be kept in directly proportional to the content of rosin. Fourth,the content of water should be kept in a low level (less than 8%);otherwise emulsifier oil will delaminate. In addition,the requisite content of sodium heavy alkyl benzene sulfonate is higher than petroleum sulfonate.

The reason may be that complex formed by rhodium and halide was difficult to produce the catalytic active species. Therefore halide ion was the poison for the rhodium catalyst in hydroformylation of olefins in ionic liquid. The effect of double long chain cationic surfactant (DCMAB, dicetyl dimethylammonium bromide) on selective hydrogenation of cinnmaldehyde catalyzed with RuCl3·x H2O/TPPTS was studied.
