Effects of Catalyst Preparation on Hydrocarbon Product Distribution in Hydrocracking of the Fischer-Tropsch Product with Low Pt-Loaded Catalysts

For the effective production of hydrocarbon liquid fuel in the hydrocracking of the Fischer-Tropsch (FT) product, the catalytic performance of Pt-loaded catalysts with low Pt content was investigated using an autoclave at 250 °C, an initial H2 pressure of 0.5 MPa, and a reaction time of 1 h. A screening study using Pt-loaded catalysts with a Pt content of 0.1 wt. % indicated that zeolite suppor...

Development of Heavy Oil Hydrocracking Catalysts

This paper present some results obtained from the research program being pursued at the Research Institute of King Fahd University of Petroleum and Minerals aimed at the development of suitable catalysts for hydrocracking of the vacuum gas oils from Arabian Light crude to obtain higher quality distillate products. The newly developed high-performance hydroprocessing catalysts are based on synth...

Hydrocracking of the oils of Botryococcus braunii to transport fuels.

Hydrocarbon oils of the alga Botryococcus braunii, extracted from a natural "bloom" of the plant, have been hydrocracked to produce a distillate comprising 67% gasoline fraction, 15% aviation turbine fuel fraction, 15% diesel fuel fraction, and 3% residual oil. The distillate was examined by a number of standard petroleum industry test methods. This preliminary investigation indicates that the ...

A 1v Second Order Sigma-delta Modulator

A second order switched capacitor sigma-delta modulator operating at a supply voltage of 1 V is presented. This low supply voltage restricts the gate overdrive voltage available for switching transistors. The design relies on the elimination of critical switches by using a modified switched op amp for the integrator and novel switched half-supply and reference voltage generators. The design has...
