In order to promote the yield and calorific value of combustible gas products in the pyrolysis, a CaO-based biochar (CSC) derived from waste crab shell was used as a low-cost sorption-enhanced catalyst to enhance oil-fried sludge (OS) pyrolysis. The effects of CSC addition and pyrolysis temperature on OS pyrolysis characteristics were analyzed in detail. The […]

Pyrolysis of oil palm biomass residue can convert the rich organic matter in biomass into sustainable green energy, thereby addressing the challenge of surplus oil palm biomass residue generated during cultivation. Nonetheless, the pyrolysis of oil palm leaves (OPLs) has received limited attention. In this study, design of experiment-response surface methodology (DoE-RSM) was employed to […]

In the context of sustainable solutions, this study examines the pyrolysis process applied to corn cobs, with the aim of producing biochar and assessing its effectiveness in combating air pollution. In particular, it examines the influence of different pyrolysis temperatures on biochar properties. The results reveal a temperature-dependent trend in biochar yield, which peaks at […]

We reviewed the potential of silicon (Si)-rich biochars (sichars) as crop amendments for pest and pathogen control. The main pathosystems that emerged from our systematic literature search were bacterial wilt on solanaceous crops (mainly tomato, pepper, tobacco and eggplant), piercing-sucking hemipteran pests and soilborne fungi on gramineous crops (mainly rice and wheat), and parasitic nematodes […]

Three different waste streams from olive oil production from Montenegro are utilized energetically by hydrothermal carbonization (HTC – hydrochar) and pyrolysis (biochar). Pyrolysis experiments of three-phase olive mill solid waste (3POMSW) were conducted for different pyrolysis temperatures of 450, 550, and 700 degrees C and a residence of 60 min for each experiment. HTC experiments […]

The higher heating value of biochar is an important parameter for the utilization of biomass energy. In this work, extreme gradient boosting regression and artificial neural network were used to predict it based on the characteristics of biomass and pyrolysis conditions. Besides, empirical correlations were developed for comparison. Results showed that the extreme gradient boosting […]

Abstract The current research focuses on assessing the potential of municipal solid waste (MSW) conversion into biofuel using pyrolysis process. The MSW samples were taken from Zaatari Syrian Refugee Camp. The physical and chemical characteristics of MSW were studied using proximate and elemental analysis. The results showed that moisture content of MSW is 32.3%, volatile […]

Abstract: Biochar, a product of pyrolysis, has been recognized for its capability to enhance soil structure and carbon sequestration. However, its potential is significantly magnified when charged with beneficial soil microorganisms. This article elaborates on the benefits of integrating microorganisms into biochar, which include improved soil fertility, disease suppression, and augmented plant growth. Detailed methods […]

Abstract Ammonia (NH3) is a potential carbon-free energy carrier. This study proposed a green route for NH3 production via microalgae steam catalytic gasification process over LaFeO3 perovskite. The experiments of pyrolysis, catalytic pyrolysis, steam gasification, and steam catalytic gasification were compared in a fixed bed reactor. Compared with pyrolysis, steam is introduced as the gasifying agent for […]
