Proton conductors capable of operating in a high temperature range (over 200°C) have received great interest for proton exchange membrane fuel cells (PEMFCs). Here, we report promising candidates for inorganic composite membranes for PEMFCs using solid CeP2O7/BPO4 and CeP2O7/BPO4/GO (without a liquid phase) at temperatures between 200°C and 300°C. BPO4 is prepared by combining a B3PO4 solution with...
Suitable supports for NiO species and NiO-support synthesis are important in CO methanation. We have used expanded multilayered vermiculite (VMT) as catalyst support and synthesized NiO/VMT composite by microwave irradiation-assisted synthesis (MIAS). Compared with conversional heat treatment (i.e., 550°C for 4h), the MIAS method provides rapid heating of the Ni/VMT precursor (i.e., 700W for 4min),...
Thermochemical conversion of crops straw is receiving renewed attention, due to the energy and material recovery that can be achieved. However, it still lacks the kinetic background which is of great importance for a successful design of thermochemical process. In this work, pyrolysis test for soybean straw was performed in a non-isothermal thermogravimetric analysis (TGA) in order to determine the...
Catalytic gasification of a pig compost (PC) was investigated over transition metal catalysts (TMCs, including limonite, CoMo/Al2O3, Ni/Al2O3, and nickel loaded on lignite char) and Ca-based catalysts (dolomite and CaO) in a two-stage fixed-bed reactor to understand the effects of catalyst, temperature, and steam on nitrogen distributions. Non-catalytic thermal decomposition (TD) of PC volatiles below...
