Abstract

Biodiesel is produced from palm oil and methanol; this methanol could be obtained from gasification of the raw palm oil residual. The complete process includes: pre-treatment of the biomass, gasification, cleaning and conditioning of the gas and the final synthesis of methanol. A review of the gasification stage is carried out, a classification of the existent gasification reactors is presented and the characteristics of three types of gasifiers are detailed. Furthermore, a summary of certain chemical and physical requirements of the gas obtained by the gasification process are introduced. Some conditions are highlighted: the ratio hydrogen to carbon monoxide ($(H{_2/CO})$ must be close to two and, the quantities of diluted nitrogen, sulphur and water in the gas must be low. Keeping in mind these characteristics we proceeded to recommend the gasifier and gasification medium. Finally, a chemical equilibrium model is introduced to estimate the composition of the gas produced and to study the effect of the temperature and operation pressure in the quality of the gas produced. The gasification process considers a fluidized bed gasifier and the simulated results are compared with experimental data. The results showed that the simulation approach accurately represents the gasification process and allows considering the simulation for some other biomass residues.

Özet

Biyodizel palmiye yağı ve metanolden üretilir; bu methanol ham palmiye yağı artıklarının gazlaştırmasından elde edilebilir. Eksiksiz bir süreç: Biokütlenin önişlemi, gazlaştırma, gazın temizlenme ve şartlandırılması ve metanolun son sentezini içerir. Gazlaştırma aşaması gözden geçirilmektedir, bugünkü tepkime odalarının bir sınıflandırması sunulmaktadır ve üç tip gazlaştıncmm özellikleri detaylandırılmaktadır. Bundan başka, gazlaştırma işlemiyle elde edilen gazın belli kimyasal ve Fiziksel gereksinimlerinin bir özeti tanıtılmaktadır. Bazı şartlar vurgulanmaktadır: Hidrojenin karbanmonoksite oranı $(H{_2/CO})$ ikiye yakın olmalı, ve gaz içindeki seyreltilmiş azot, kükürt ve su az olmalı. Bu özellikleri akılda tutarak gazlaştırıcı ve gazlaştırma ortamı önerme aşamasına geçmekteyiz. Son olarak, üretilen gazın birleşimini öngörmek ve sıcaklık ve işletim basıncının üretilen gazın niteliğndeki etkisini incelemek için bir kimyasal denge modeli tanıtılmaktadır. Gazlaştırma işlemi bir akışkan yataklı gazlaştırıcı dikkate almaktadır ve benzeşik sonuçlar deneysel verilerle karşılaştırılmaktadır. Sonuçlar benzetim yaklaşımının gazlaştırma işlemini doğru olarak temsil ettiğini ve diğer bazı biyokütie artıkları için benzetimin dikkate alınabileceğini göstermektedir.
