The process consists of a mild alkaline extraction, followed by acidification, ozonation, and final bleaching. The ozone stage serves as a chemical depithing stage and permits free-draining pulps to be produced without mechanical depithing. In this paper, preliminary data are shown for trails on US corn stalks. Strength properties of handsheets from corn stalks pulps were compared to those for southern hardwoods.</div> <bR> <div> The PowerPoint presentation of the paper in PDF format can be downloaded at the following link:</div> <bR> <div>  <a href="HTMLobj-996/Corn_Stalks_PAPTAC_2005.pdf"><img align="bottom" border="0" width="153" height="17" alt="Simplified Pulping and Bleaching of Corn Stalks" src="HTMLobj-996/download_pdf_LG_LARGE.gif"></a>  (requires Adobe Reader).</div> <bR> <div> <FONT SIZE="3" COLOR="#000000" FACE="Arial" >Dr. Byrd and Mr. Hurter were granted </FONT><A HREF="us_patent_6_302_997.htm" TARGET="_top" TITLE="United States Patent 6,302,997 Process ">United States Patent 6,302,997 - Process for producing a pulp suitable for papermaking from nonwood fibrous materials</A>  <FONT SIZE="2" COLOR="#111111" FACE="Arial" >(2001) for this process.  Patent protection is being processed for the European Union, Canada, Mexico, India, China and other countries.</FONT></div> <bR> <bR> <div> <TABLE BORDER="0" CELLPADDING="2" CELLSPACING="3" WIDTH="98%" BORDERCOLORLIGHT="#C0C0C0" BORDERCOLORDARK="#808080" FRAME="BOX" RULES="ALL" ALIGN="LEFT" HSPACE="0" VSPACE="0" > <tR> <tD VALIGN=TOP HEIGHT= 2 WIDTH="100%"><div> <A HREF="index.htm" TARGET="_top" TITLE="HurterConsult Incorporated">Home</A> / <A HREF="philosophy.htm" TARGET="_top" TITLE="Our Process Technology Design Philosoph">Process Technology & Design Philosophy</A> /<B> </B><A HREF="expertise.htm" TARGET="_top" TITLE="Our Areas of Expertise">Areas of Expertise</A><B> </B>/<B> </B><A HREF="services.htm" TARGET="_top" TITLE="Our Scope of Services">Scope of Services</A> / <A HREF="cellulosic_biofuels.htm" TARGET="_top" TITLE="Cellulosic Biofuel">Cellulosic Biofuel</A></div> <div> <A HREF="references.htm" TARGET="_top" TITLE="HurterConsult Project References">Project References</A> / <A HREF="info.htm" TARGET="_top" TITLE="HurterConsult News Info"><B>News & Info</B></A> / <A HREF="links.htm" TARGET="_top" TITLE="HurterConsult Favorite Links">Links</A> / <A HREF="contact.htm" TARGET="_top" TITLE="Contact HurterConsult">Contact Us</A> / <A HREF="legal_notice.htm" TARGET="_top" TITLE="Legal Notice About This Web Site">Legal Notice</A></div> <bR> <div> <A HREF="tappi_2005_paper.htm" TARGET="_top" TITLE="Simplified Pulping and Bleaching of Pith"><B>Up</B></A><B> </B><B> /  </B><A HREF="aafc_pulp_paper.htm" TARGET="_top" TITLE="Strategic Market Management System Pulp"><B>Down</B></A><B>  /  </B><A HREF="contact.htm" TARGET="_top" TITLE="Contact HurterConsult"><B>Contact Us</B></A></div> <div> <B>  <center> <FORM method=GET action="http://www.google.com/search" TARGET=_blank> <input type=hidden name=ie value=UTF-8> <input type=hidden name=oe value=UTF-8> <TABLE bgcolor="#FFFFFF"><tr><td> <A HREF="http://www.google.com/" TARGET=_blank> <IMG SRC=http://www.google.com/logos/Logo_40wht.gif border="0" ALT="Google" align="middle"></A> </td> <td> <INPUT TYPE=text name=q size=31 maxlength=255 value=""> <INPUT type=submit name=btnG VALUE="Google Search"> <input type=hidden name=domains value="www.HurterConsult.com"><br><input type=radio name=sitesearch value=""> Search WWW <input type=radio name=sitesearch value="www.HurterConsult.com" checked> Search www.HurterConsult.com <br> </font> </td></tr></TABLE> </FORM>   </B></div> <bR> <div> <B>Copyright © 2000-2010 HurterConsult Incorporated.  All rights reserved.</B></div> <bR> </tD> </tR> </TABLE></div> <bR> <bR> <bR> </td> </tr></table></body>
