<![CDATA[Increased fuel consumption of oil has an impact on the energy crisis. Biogasolin is an alternative fuel from vegetable oil that has the potential to overcome this problem. One of the methods used to produce biogasoline is the catalytic string method. Such methods generally use a catalyst to help speed up reactions. The use of catalysts in the cracking process is increasingly diverse. In this review article will compare the biogasoline percent value between several types of catalysts focused on zeolite and zeolite catalysts that are modified with metal, including the general picture of the arrest of the material, type and characteristics of the zeolite catalyst, operating conditions, and ways of performance of each catalyst. Zeolite catalyst which is a heterogeneous catalyst is considered to have good ability in selectivity, activity, and ease of modification so that it is very influential on the cracking results. Some zeolite catalysts modified with metals such as nimo/zeolite; Zn/HZSM-5; Cu/HZSM-5; Ni/HZSM-5; MO/HZSM-5; HZSM-5; PD/HZSM-5; PT/HZSM-5; Zn/Na-ZSM-5; Ni/ZSM-5; Ni/mnz; Co-NI/HZSM-5 and each biogasoline is obtained at 11.93%; 28.38%; 17.55%; 32-37%; 9-23%; 30.2%; 32-41%; 11.73% are reportedly able to provide performance to improve biogasoline results and certainly become a new catalyst that is useful in the scientific world]]>
