  • Dispersed noble metal-containing catalyst for hydrocarbon conversion
    Patent number: 10239053
    Abstract: A method for modification of pretreated acidic porous material via selective cation exchange using suitable solvent to obtain higher noble metal dispersion is described herein. The solvent system required for cation exchange should have its dielectric constant in the range of 25-45, wherein this solvent property is found to impart significant effect on cation loading and distribution, which in turn defines the stability, dispersion of the noble metals. The catalyst so obtained has higher noble metal dispersion and when used for hydroisomerization reaction, leads to higher selectivity even at significantly high conversion values.

  • A SULPHUR ADDITIVE TO SUPPRESS HYDROGEN SULPHIDE EMISSIONS FROM SULPHUR EXTENDED ASPHALT
    Publication number: 20180105694
    Abstract: The present disclosure relates to a sulphur additive to suppress hydrogen sulphide emissions from Sulphur Extended Asphalt. The sulphur additive of the present disclosure comprises 5 sulphur in an amount ranging from 80 to 98 wt % and at least one aluminosilicate in an amount ranging from 2 to 20 wt %. The sulphur additive of the present disclosure suppresses the H2S emission up to acceptable safe limit during the preparation and application of the sulphur extended asphalt at elevated temperature.
