This research paper presents a detailed review of the recent advances concerned with carrying out efficient solar chemical reactions by reviewing most reactors available in literature that use solid-gas or pyrolysis processes. Major groups chemistry design and manufacture wide range reactor configurations, widths, sizes, including directly radioactive particles. Solar heat up to 1000℃ can be ut...

Polyethylene (PE) and polypropylene (PP) make up for a large part of the total worldwide polymer production. Originally, both polymers were often produced in solution processes. However, fluidized bed reactors for polyethylene and polypropylene production gain increasing industrial interest because of the relatively low production costs, the ability to produce a wide range of polymer grades, an...

In this paper, the effect of fluidized bed temperature on primary fragmentation of Huadian oil shale was investigated experimentally in thermal state using a small-scale fluidized bed with N2 as fluidizing gas. The fluidized-bed temperatures changed from 600 °C to 1000 °C. Experimental results indicate that the fluidized bed temperature is an important factor of primary fragmentation of oil sha...

An accurate prediction of the minimum fluidization velocity is a crucial hydrodynamic aspect of the design of fluidized bed reactors. Common approaches for the prediction of the minimum fluidization velocities of binary-solid fluidized beds are first discussed here. The data of our own careful experimental investigation involving a binary-solid pair fluidized with water is presented. The effect...

Abstract A compartmental one‐dimensional model of a fluidized bed pyrolytic converter biomass is presented. Reference conditions are those non‐catalytic fast pyrolysis in shallow with external regeneration the material. The fate and resulting char has been modelled by considering elutriation particles, attrition as well drain/regeneration. course primary secondary pyrolitic reactions according ...

we evaluated the efficacy of a full-scale combined biophysicochemical system for treatingmolasses-based bioethanol wastewater in terms of organic substances, nutrient, and dark brown color removal. the main organic removal unit, i.e., the upflow anaerobic sludge blanket (uasb) reactor, achieved 80.7% removal and 4.3 nm3 methane production per cubic meter of wastewater with a hydraulic retention...
