1. Introduction
Gas-to-Methanol (GTM) process based on the methanol synthesis have attracted significant attention over the past decade because of the generally increasing trend in methanol demand and the abundant natural gas supply available at relatively low prices [1]. Methanol is a very important primary raw material for the petrochemical and energy industries because of its wide applications, ranging from chemical uses (e.g., as a solvent or an intermediate for producing olefins, formaldehyde, acetic acid and esters) to energy uses (e.g., as a fuel by itself, blended with gasoline, or for use in direct methanol fuel cells) [2–4]. Methanol will become an even more important commodity in the coming years, thanks largely to the unconventional but extremely abundant natural gas resources, such as shale gas and coal-bed methane which have been recently exploited through the development of horizontal drilling and hydraulic fracturing technologies [5–8].
مقدمه
فرآیند تبدیل گار به متانول (GTM) بر پایه پیوند و ترکیب متانول در دهه گذشته توجه زیادی را به خود جلب کرده‌است، زیرا به طور عمومی تقاضا برای متانول در حال افزایش می‌باشد و عرضه گاز طبیعی با قیمت نسبتا کم صورت می‌گیرد. متانول یکی ار مهم‌ترین مواد خام اولیه برای پتروشیمی و صنعت تولید انرژی می‌باشد. دلیل آن را می‌توان استفاده بسیار وسیع ماده دانست. محدوده استفاده آن از شیمی (به عنوان مایع حلال یا ماده اولیه تولید اولفین، فرمالدهید، استیک اسید و…) گرفته تا صنعت تولید انرژی (به خودی خود به عنوان سوخت و یا در ترکیب با گازوئیل و یا استفاده در سلول های سوختی متانولی) گسترده است. متانول حتی می‌تواند به کالای مهم‌تر در سال های آینده بدل شود. این موضوع را می‌توان تحت تاثیر منابع فراوان گاز طبیعی مانند گاز شیل و متان موجود بر بستر ذغال سنگی که به تازگی در شکاف‌های افقی و تکنولوژی شکافتن هیدرولیکی بسیار مورد توجه قرار گرفته‌است، دانست.
