Abstract

Municipal solid waste (MSW) disposal is one of the main issues towards sustainable development. Various technologies are studied to solve it. Hydrothermal carbonization (HTC) is an appropriate technology selection to reduce the waste volume primarily and to utilize MSW as the energy source because of its high the calorific value inside. This paper describes the potential of hydrochar production of raw materials in the provinces of East Java, Indonesia. The hydrochar production can be used as a secondary char and for electrical generation if it is combined with gasification process. The waste material affected the quality of combustion and calorific value to the product. The proximate and ultimate analysis using ASTM methods was conducted to analyze the characteristics of hydrochar. The influences of the HTC temperatures at saturated pressure (220°C, 23 bar) and variations of the feedstock moisture content (20–60%) were studied using a simulation of HTC process. The average calorific value of hydrochar is increased 32% of waste materials, 70% hydrochar yield, and 84% energy efficiency. This value indicates that the HTC process can produce hydrochar, moreover it reduced the mass of waste materials, also increased the energy content of products and the energy efficiency is a potential of energy generation from waste materials in an area.

通过HTC工艺生产碳氢化合物：以印度尼西亚东爪哇省的城市固体废物样本为例

摘要

城市固体废物（MSW）的处置是实现可持续发展的主要问题之一。研究了各种技术来解决它。水热碳化（HTC）是一种合适的技术选择，主要是减少废物量并利用城市固体废弃物作为能源，因为其内部的热值很高。本文介绍了在印度尼西亚东爪哇省生产碳氢化合物原料的潜力。如果将水焦炭生产与气化工艺结合使用，则可以用作辅助焦炭并用于发电。废料影响燃烧质量和产品的热值。使用ASTM方法进行了近距离和最终分析，以分析水焦的特性。使用HTC过程的模拟研究了HTC温度在饱和压力（220°C，23 bar）下的影响以及原料水分含量的变化（20-60％）。水炭的平均发热量增加了32％的废料，70％的水焦收率和84％的能源效率。该值表明HTC工艺可以产生碳氢化合物，而且减少了废料的质量，还增加了产品的能量含量，而能源效率是一个地区从废料中产生能量的潜力。
