1. Introduction
Methanol could be one of the main fuels used in future
transportation when petroleum wells are depleted. Methanol
is produced from synthesis gas (mixture of carbon mono
oxide and hydrogen), which is formed by steam reforming of
natural gas or gasification of coal or from biomass. Methanol
is available in abundance, therefore it has been used as a raw
material for the production of gasoline and olefins. It can be
obtained from renewable sources such as biomass.
Catalytic conversion of methanol to gasoline and olefins
attracted many researchers when the price of fuel started to
increase. The literature concerning conversion of methanol
to hydrocarbons over zeolite catalyst is extensive [1–13].
In 1970s, Mobile researchers found that methanol could be
converted to gasoline over mesoporous selective zeolites.
Conversion of hydrocarbons from methanol using ZSM-5
has been investigated by Chang and Silvestri[7]. Dubo is et al.[6]reported the effect of transition metals Co, Mn and
Ni over SAPO-34 molecular sieve to check the activity and
conversionใ
