ABSTRACT

The cracking oflong chain hydrocarbons can be carried out either thermally or

catalytically; for this purpose, zeolite Y catalyst is commonly used for petroleum

cracking. The catalytic crackings oflong chain hydrocarbons are closely related to the

acidity and the reactivity of metal content in catalyst. Hydrocracking is a combination

of catalytic cracking and hydrogenation. In this research,

refined-bleached-deodorized-palm oil ( RBDPO) will be subjected to catalytic hydrocracking over lSM-5 or

13

zeolite

by impregnating a mixture of copper and gallium metals in different weigh percent

ratios. The performance of the catalysts is tested in micro fixed bed reactor. Palm oil

will be injected to the system with a syringe pump, then the oil will be preheated and

evaporated. The palm oil vapor and hydrogen gas will

be

allowed into the reactor and

the reaction product will be condensed to complete gas and liquid products. The

evaporation temperature of palm oil and reactor temperature will be set at temperature

range between 150

0

C and 350

0

C, and from 340

0

C to 380

0

C, respectively. The weight

hourly space velocity (WHSV) of palm oil will be varied between 1.0 h-I and 3.0 h-I.

The pressure of hydrogen gas will be varied between 0 and 8 bars, while the weight

percent of each metal copper and gallium in zeolite will be varied between 0 and 8 wt

'Yo.

The main objective is to study the effect of all independent variables on gasoline rich

product using design of experiment (DOE). Screening of these variables will be

performed using Plackett-Burman Design (PBD), while optimization is to be canied out

using central composite design (CCD). The gas and liquid products will be analyzed by

gas chromatograph with HP- I capillary column and the catalyst before and after reaction

will be characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR),

temperature programmed desorption (TPD) and nitrogen adsorption (NA) methods.
