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.

Tar Formation in Gasification Systems: A Holistic Review of Remediation Approaches and Removal Methods

ACS Omega, Journal Year: 2024, Volume and Issue: 9(2), P. 2060 - 2079

Published: Jan. 4, 2024

Gasification is an advanced thermochemical process that converts carbonaceous feedstock into syngas, a mixture of hydrogen, carbon monoxide, and other gases. However, the presence tar in which composed higher molecular weight aromatic hydrocarbons, poses significant challenges for downstream utilization syngas. This Review offers comprehensive overview from gasification, encompassing gasifier chemistry configuration notably impact formation during gasification. It explores concentration composition syngas purity required applications. Various removal methods are discussed, including mechanical, chemical/catalytic, plasma technologies. The provides insights strengths, limitations, associated with each method. also highlights importance integrating multiple techniques to enhance efficiency quality. selection appropriate strategy depends on factors such as composition, operating design factors, economic considerations, extent at application. Future research should focus developing cleaning strategies consume less energy cause smaller environmental impact.

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.
