Effect of CeO2 morphology on the catalytic properties of Au/CeO2 for base-free glucose oxidation

Catalytic selective oxidation of glucose into value-added gluconic acid is one of the sustainable routes for biomass utilization, for which the supported Au catalysts have been widely explored. Au/CeO2 was...

The potential and prospect of biomass as primary energy in Indonesia

Energy is one of the needs to support daily human activities. Without energy, various activities such as industry, health, and household will be disrupted. Total energy consumption in Indonesia in 2018 reached 875 million barrels of oil equivalent (BOE), which was dominated by fuel oil. It illustrates that national energy consumption is still dominated by primary energy sources originating from fossil fuels. Various previous studies have suggested the environmental and health impacts of air pollution from burning fossil fuels. This article will briefly discuss biomass as a primary energy source based on the results of literature studies. The discussion section will discuss the environmental impacts of biomass utilization based on several scientific studies and the form of biomass utilization in Indonesia that has been carried out. As a follow-up to several scientific facts, it is necessary to mix other primary energy from new and renewable energy sources.

COMBINED BIOMASS UTILIZATION SYSTEM

The purpose of this study is to analyze existing technologies and optimize their operation in a closed-loop production and use of biomass fuel based on existing chemical-biological technologies of biochemical processing of biomass and its anaerobic fermentation processes. The article presents a fundamentally new scheme of biomass utilization of different origins, the implementation of this scheme of utilization of household, sewage, industrial and technological biomass waste will solve simultaneously the problem of preserving the environment in an environmentally friendly condition, to obtain during processing energy sources thermal energy to ensure the flow of biochemical and thermal processes in the installation, and to produce pilot fuel for its use in the processes of heat production of decentralized heating systems and energy production of small and medium-sized settlements, private estates and cottages.
