The first stage is catalyst activation using ammonium nitrate and hydrochloric acid. The second stage is impregnation of Ni, Cr, and Ti metal ions into the activated catalyst. The last step is the impregnated catalyst calcination at a temperature of 500oC. Characterization of the bifunctional catalyst of zeolite included analysis of the chemical composition contained therein using EDX, the crystalline phase of the catalyst using XR-D, the amount of acidity using the gravimetric method, the surface area of the catalyst using the methylene blue method, and the description of the surface morphology of the catalyst using SEM. The results of the characterization that have been carried out are the XR-D results showing that the calcined catalyst in this study has an amorphous crystal phase and dominance, the surface morphology of the catalyst analyzed using SEM shows a crystalline form consisting of a lamellar layer with pore cavities classified as micropores The surface measured by the methylene blue method of all catalysts which assessed the specific surface area was quite large, namely 110 m2 / g. The amount of catalyst acidity measured by the gravimetric method yielded a result of 3.00 -3.70 mg NH3 / g.

The manufacture of biofuels is the solution to this problem. The results of previous research showed that palm oil can be converted into a fraction equivalent to biogasoline by using a catalytic Cracking Reaction. The purpose of this research was to determine the compounds contained in the biogasoline from palm oil with the optimum catalyst and flow rate. The catalyst used in this study was natural Ni / Zeolite. The catalyst was prepared by impregnation with Ni metal content of 1%, 2% and 3% by weight of zeolite. Catalyst characterization includes: determination of the surface area of the catalyst using the BET method, determining the number of acid sites using the gravimetric method, and determining the content of Ni metal embedded in the catalyst using AAS. Palm oil is first esterified using methanol and KOH, then cracking is carried out with a fixed bed flow reactor at an operating temperature of 450° C. The analysis using GC shows that the condensation fraction of the biogasoline product reaches 100 % at a hydrogen gas flow rate of 20 mL / minute.
