english proofreading project. Content is about chemical "A carbon-based solid acid catalyst was prepared by incomplete carbonization of H3PO4 acacia mangium wood sawdust followed by sulfonation. XRD, FT-IR, BET and TPD-NH3 were used to characterize the structure and performance of the catalyst. Results showed that the catalyst was amorphous carbon composed of aromatic carbon sheets with –COOH, –OH and –SO3H groups. Previous impregnation with H3PO4 could promote formation of mesoporous catalyst. The optimized carbonization temperature and time for the catalyst were 500oC and 30 minutes. The –SO3H density and specific surface area for the catalyst prepared under the optimized conditions were 2.9-3.2 mmol/g and about 740 m2/g. The acacia mangium wood sawdust was also pretreated by alkaline solution for obtaining of pulp, which was saccharificated by Novozymes commercial enzyme and used for conversion into hydroxymethylfurfural by above mentioned solid acid catalyst. The integrated scheme for preparation of solid acid catalyst and hydroxymethylfurfural from acacia mangium wood is efficiency conversion of wood biomass into green catalysts and chemicals. Keywords: biochar, wood sawdust, solid acid catalyst, sulfonated carbon, 5-hydroxymethylfurfural."

Hi, What are you searching for when you need somebody to edit or proofread your work? Affirmation. That is the thing that I give to my customers; an accomplished and gifted proficient essayist with faultless language structure expertise, solid visual mindfulness, and an emphasis on spelling flawlessness. Rest guaranteed that when I alter, edit, and investigate a record of any size it will be returned in free of blunders. You require a "linguistic fussbudget, for example, me in the event that you need confirmation. I will break down, alter, overhaul, and revamp as fundamental so you will be left with a predominant completed item. I alter, edit, and revamp the majority of my content physically without the utilization of internet modifying programs. At the point when quality checks, reach me. Best respects
