With the growing human demand for energy and fossil fuels are dwindling , looking for the sustainable use of new energy has become an urgent task . Biomass as a renewable energy source , has been subject to the attention of the world , research and development and utilization of biomass has become an important task of the world . Biomass energy conversion of biomass pyrolysis is a promising technology . Microns pine sawdust , as the raw materials, the use of Ni -based catalysts , pyrolytic and catalytic cracking experiment is carried out in a fixed bed apparatus , and the composition of the product was analyzed , preliminary study the influence of the catalyst , temperature, and water vapor on the experiment . Experimental results show that : the Ni catalyst to promote the cracking of the tar , can increase gas production and to improve the gas quality , catalytic performance is superior to the calcined dolomite ; With the rise of the catalyst temperature , the decrease in the content of tar and coke , gas production is greatly improved , H 2 and CO content increased significantly help to generate more combustible gas ; biomass catalytic cracking pass into water vapor , tar and coke decreased , H 2 content and a significant increase in gas production . Meanwhile, this paper studied the characteristics of activation after pyrolysis coke and its adsorption properties of the copper ion in wastewater , investigate the adsorption time , the adsorption of carbon residue particle size , pH value and other factors . The results show that the activated coke copper ion adsorption conditions : particle size 0.3 - 0.45mm , adsorption time 120min, the pH value of 6.2 , corresponding to the adsorption rate can reach 85% or more .
