The optimum values obtained from the batch study were 20% impregnation of H3PO4
, 500[degrees]C of carbonization for 2 hours using real car wash wastewater as sample.
solution allowed obtaining an oxide layer with a porous structure characterised by a flowery pattern and average pore size between 0.
In the present study the alkylation of toluene with isopropanol to produce cymenes over ZSM-5 zeolite has been carried out on two series of H3PO4
loaded ZSM-5 zeolite catalysts, same as the catalysts which were prepared and used for toluene methylation and the results are presented in the following sections.
25 ml of H3PO4
was added after cooling and the final volume was raised to 100ml by using distilled water.
5 ml of Griess reagent (1% sulfanilamide, 2% H3PO4
(B) in a gradient as follows: initial 10:90 (A:B) increased to 25:75 for 10 min, isocratic at 25:75 for 5 min, then run to 50:50 at the 30th min, to 65:35min at the 45th min, to 80:20 at the 55th min and changed to 0:100 after 5 min followed by an isocratic hold for 10 min, and finally reconditioning for 20 min.

, Fuel Process.
In addition, phosphoric acid medium that does no harm to Pd-C catalyst is reported firstly in hydrogenation of 3,4-NHBA, and the product 3,4-AHBA H3PO4
meets requirement of polymerization reaction of poly(2,5-benzoxazole) directly without dehydrochlorogenation.
