Evaluating technical parameters for microalgae immobilization to optimize green hydrogen photoproduction: A comparative review

International Journal of Hydrogen Energy, Journal Year: 2024, Volume and Issue: 67, P. 925 - 932

Published: Feb. 4, 2024

Microalgae are photosynthetic microorganisms that have been extensively studied for their ability to produce biofuels, including hydrogen (H2). While microalgae immobilization techniques researched wastewater treatment, application H2 photoproduction is a relatively new area of study. In this review, we evaluate as promising technology improve the commercial maturity green production by microalgae, it offers multiple advantages over traditional suspended growth systems. It facilitates cell harvesting, reduces contamination risk, and improves control cultivation conditions, biomass retention, efficiency production. However, effectiveness largely depends on technical parameters, type method used, choice materials, operational conditions. Here provide comparative review different parameters conditions suggested in literature immobilization, propose protocol optimized achieve an efficient

Using NaOH@Graphene oxide-Fe3O4 as a magnetic heterogeneous catalyst for ultrasonic transesterification; experimental and modelling

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: June 22, 2024

Abstract Burning fossil fuels causes toxic gas emissions to increase, therefore, scientists are trying find alternative green fuels. One of the important is biodiesel. However, using eco-friendly primary materials a main factor. Sustainable catalysts should have high performance, good activity, easy separation from reaction cells, and regenerability. In this study, solve mentioned problem NaOH@Graphene oxide-Fe 3 O 4 as magnetic catalyst was used for first time generate biodiesel waste cooking oil. The crystal structure, functional groups, surface area morphology were studied by XRD, FTIR, BET, FESEM techniques. response methodology based central composite design (RSM-CCD) production via ultrasonic technique. maximum yield 95.88% in following operation: 10.52:1 molar ratio methanol oil, weight 3.76 wt%, voltage 49.58 kHz, 33.29 min. physiochemical characterization ASTM standard. standstill free fatty acid due five cycle’s regeneration. kinetic study results possess agreement with first-order kinetics well activation energy Arrhenius constant 49.2 kJ/min 16.47 * 10 min −1 , respectively.

Bio-Nanoparticles Mediated Transesterification of Algal Biomass for Biodiesel Production

Sustainability, Journal Year: 2023, Volume and Issue: 16(1), P. 295 - 295

Published: Dec. 28, 2023

Immense use of fossil fuels leads to various environmental issues, including greenhouse gas emissions, reduced oil reserves, increased energy costs, global climate changes, etc. These challenges can be tackled by using alternative renewable such as biodiesel. Many studies reported that biodiesel production from microalgae biomass is an environment-friendly and energy-efficient approach, with significantly improved fuel quality in terms density, calorific value viscosity. Biodiesel produced the transesterification process most sustainable method utilizing enzymes for transesterification. Lipase enzyme excellent catalytic activity, specificity, enantio-selectivity, compatibility stability hence it applied production. But, difficulty enzymatic recovery, high cost minimal reaction rate are some its drawbacks have addressed. In this aspect, nanotechnological approach lipase immobilization producing a promising way increase yield due adsorption efficiency, economic benefit, recyclability, crystallinity, durability, stability, friendliness performance bio-nanoparticles used. Through increasing post-harvest yield, absorption CO2 photosynthesis photobioreactor, nanoparticle immobilized during generation has potential also remove feedstock availability constraints. This review article discusses biodiesel, effect nanoparticles on The advantages introducing large-scale discussed. Reducing water land use, nutrient footprints integrated algae-based operations must main goal larger-scale experiments well ongoing research development order expedite adoption microalgae-based Also, cost-effectiveness impact engine should analyzed commercialization

Development of Biocatalysts Based on Candida Antarctica B Lipase Immobilized Onto Crosslinked Porous Polymers Containing Varied Monomeric Compositions

Journal of Applied Polymer Science, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 13, 2025

ABSTRACT Crosslinked polymer particles can be used successfully as support for enzyme immobilization. For this reason, the relationship between particle morphology and immobilization parameters is investigated in present manuscript. Particularly, study focuses on preparation of biocatalysts using lipase from Candida antarctica B (Cal‐B) crosslinked polymers made divinylbenzene (DVB) ethylene glycol dimethacrylate (EGDMA). Several monomers were utilized process, including methyl methacrylate (MMA), styrene (Sty), glycidyl (GMA), methacrylic acid (MA), vinylbenzyl chloride (VBC), 2‐vinylpyridine (Vpy). Many these to synthesize first time. The highest yields achieved Sty‐DVB, MA‐DVB, DVB supports, which presented high surface areas pore diameters. Among developed biocatalysts, CalB‐MMA‐DVB, a specific area 320.9 m 2 /g, esterification activity 1410 ± 176 U/g bio −1 . In contrast, manufactured with smaller but containing polar monomers, such Cal‐B‐MA‐EDGMA, Cal‐B‐GMA‐EDGMA, Cal‐B‐Vpy‐DVB, Cal‐B‐VBC‐EDGMA, higher hydrolytic activities (HA).
