Optimizing biomass pathways to bioenergy and biochar application in electricity generation, biodiesel production, and biohydrogen production

Environmental Chemistry Letters, Journal Year: 2023, Volume and Issue: 21(5), P. 2639 - 2705

Published: June 28, 2023

Abstract The current energy crisis, depletion of fossil fuels, and global climate change have made it imperative to find alternative sources that are both economically sustainable environmentally friendly. Here we review various pathways for converting biomass into bioenergy biochar their applications in producing electricity, biodiesel, biohydrogen. Biomass can be converted biofuels using different methods, including biochemical thermochemical conversion methods. Determining which approach is best relies on the type involved, desired final product, whether or not sustainable. Biochemical methods currently most widely used from biomass, accounting approximately 80% all produced worldwide. Ethanol biodiesel prevalent via processes. Thermochemical less than conversion, 20% Bio-oil syngas, commonly manufactured wood chips, agricultural waste, municipal solid major by conversion. Biofuels potential displace up 27% world's transportation fuel 2050, could result a reduction greenhouse gas emissions 3.7 billion metric tons per year. Biochar yield high ranging 32.8% 97.75%, also serve as an anode, cathode, catalyst microbial cells with maximum power density 4346 mW/m 2 . plays role catalytic methane decomposition dry reforming, hydrogen rates 13.4% 95.7%. increase 220.3%.

Optimizing biodiesel production from waste with computational chemistry, machine learning and policy insights: a review

Environmental Chemistry Letters, Journal Year: 2024, Volume and Issue: 22(3), P. 1005 - 1071

Published: Feb. 13, 2024

Abstract The excessive reliance on fossil fuels has resulted in an energy crisis, environmental pollution, and health problems, calling for alternative such as biodiesel. Here, we review computational chemistry machine learning optimizing biodiesel production from waste. This article presents techniques, characteristics, transesterification, waste materials, policies encouraging Computational techniques are applied to catalyst design deactivation, reaction reactor optimization, stability assessment, feedstock analysis, process scale-up, mechanims, molecular dynamics simulation. Waste comprise cooking oil, animal fat, vegetable algae, fish waste, municipal solid sewage sludge. oil represents about 10% of global production, restaurants alone produce over 1,000,000 m 3 annual. Microalgae produces 250 times more per acre than soybeans 7–31 palm oil. Transesterification food lipids can with a 100% yield. Sewage sludge significant biomass that contribute renewable production.

Waste Gasification Technologies: A Brief Overview

Waste, Journal Year: 2022, Volume and Issue: 1(1), P. 140 - 165

Published: Dec. 17, 2022

This paper aims to briefly overview gasification technologies of biomass and heterogeneous wastes as a means for syngas production. For this purpose, an the existing technologies, their main advantages, limitations, costs, well commercial plants projects (lower TRL) operating with these applications is presented. The type technology parameters should be selected considering quality it will dictate its end use. Syngas determined by combination feedstock properties, process conditions, scale operation. smaller capacity up 10 MWth, fixed-bed have been recurring choice, while fluidized bed reactors can installed above 100 MWth are, therefore, more suitable medium- large-scale projects. Fluidized supports flexibility, has scale-up potential, presents relatively low cost, making solution frequent choice waste in or Commercializing already reality. However, efforts need made so that pilot demonstration overcome technological economic problems move towards commercialization.

An analysis of waste/biomass gasification producing hydrogen-rich syngas: A review

International Journal of Thermofluids, Journal Year: 2023, Volume and Issue: 20, P. 100492 - 100492

Published: Oct. 18, 2023

In the last few decades, population growth level has increased exponentially so waste disposal gradually. Wastes like biodegradable wastes, kitchen hotel and other agro wastes can be processed through bio methanation composting technology but non-biodegradable materials plastics, rubber, industrial sludge, cannot in simple ways or technologies. These are critical to handle need robust technology. Gasification incinerators a utilize these convert them into useful energy. However, incinerator drawback of control over emissions generated by material combustion. is best-suited which gaseous form this gas provides heat prime movers generate energy/power. Carbon monoxide, hydrogen, methane, carbon dioxide, oxygen, nitrogen main components synthetic (syngas), low calorific value. Increased hydrogen monoxide concentrations improve gas's Different gasification methods using agent as steam, catalytic gasification, different combination fuels (waste-coal/biomass) used enrich content syngas. This paper reviewed theory waste-to-energy technologies, incineration technology, for increasing syngas, also methods. review discusses enrichment.
