摘要

在过去的二十年中,生物质已成为最常用的可再生能源之一。空果束(EFB)是将生物质用作可再生能源的一个例子。从棕榈油加工业中,只有10%是棕榈油和棕榈仁油等最终产品,而其余90%是EFB,棕榈仁壳(PKS)和油棕榈叶(OPF)形式的可收获生物质废物。这种过量的生物质废物将导致大量的废物,这也将影响环境。为了以更高效、更少污染和更经济的方式将EFB转化为可用能源,气化已成为合成气生产中最有利的技术创新之一。本研究的主要目的是在不同操作温度(700°C至900°C)和等效比ER(0.2 - 0.4)的基础上研究夹带流气化过程中的EFB气化,并根据氢气(h2)、一氧化碳(CO)、二氧化碳(CO 2)和甲烷(ch4)等气体的产生进行评估。结果表明,当温度从700℃升高到900℃时,h2和CO的生成量增加,CO的生成量减少。在900℃时,最佳ER值为0.30,可获得74.03%的最高冷气效率(CGE)。化工研究通报19(2017)43-49

Empty Fruit Bunch (EFB) Gasification In An Entrained Flow Gasification System
Biomass has become one of the most commonly used renewable sources of energy in the last two decades. Empty fruit bunch (EFB) is one of the examples for the biomass that is used as a renewable energy source. From the palm oil processing industry, only 10% are the final products such as palm oil and palm kernel oil, while the remaining 90% are harvestable biomass waste in the form of EFB, palm kernel shell (PKS) and oil palm frond (OPF). This overload amount of biomass waste will cause an abundance of waste which will also affect the environment. To convert EFB into usable energy in ways that are more efficient, less polluting, and economical, gasification has merge as one of the most favorable technological innovations in synthesis gas (syngas) production. The main aim of this work is to study the EFB gasification in an entrained flow gasification process based on the different operating temperature (700 ° C to 900 ° C) and equivalence ratio, ER (0.2 – 0.4), evaluated based on the production of gases such as hydrogen (H 2 ), carbon monoxide (CO), carbon dioxide (CO 2 ) and methane (CH 4 ). It was found that as the temperature was increased from 700 ° C to 900 ° C, the production of H 2 and CO 2 increased while CO was decreased. The optimum ER value of 0.30 was found to attain the highest Cold Gas Efficiency (CGE) value of 74.03% at 900°C. Chemical Engineering Research Bulletin 19(2017) 43-49
